Step 3: Position lifting device and attach sling

Position the lifting device above the motor and attach the sling to each lifting lug.

Step 4: Lift motor out of the crate

Lift the motor vertically and keep the shaft unloaded.

Step 5: Position motor and lower motor onto cart

Slowly move the lifting device horizontally until it is positioned over a support cart. Lower the motor onto the support cart so it is resting on the C-face and not the shaft.

CAUTION!

Do not lift or rest the motor on the shaft.

Do not slide, spin, or roll the motor onto the drive without a rubber mat or other protective material placed under the drive to protect the light pipes and finish.

 

4.3 Transport motor

When transporting a motor within the production facility, follow the instructions outlined below.

DO		x DO NOT
• Transport motors shaft down only if they are fully supported (C-face through cart opening or supported by 2x4s).	• Secure motors to prevent shifting during transportation.	Allow the motor’s weight to rest on the shaft. Let motors contact hard surfaces without protection.

4.4 Support and flip assembly

 

Before working on the motor and assembly, make sure the assembly is properly supported using a fixture or stand.

DO		x DO NOT
Support assemblies during flips so no weight is carried by the shaft or equipment coupled to and supported by the motor shaft. Use fixtures or stands whenever possible.		Rest the full motor or assembly weight on the wheel or shaft. Step on the wheel or fan for balance when entering/exiting the unit.

4.5 Compare nameplate data

 

Verify receipt of the proper motor:

• Compare data on the nameplate (Figure 3) with the purchase order. Labels are on the motor shroud.
• Compare data on the nameplate for the desired power supply and control equipment requirements.

4.6 Confirm catalog number

 

Infinitum Aircore EC+ motors are ordered with catalog numbers using a decoder scheme (Figure 4).

Figure 4: Catalog number decoder

4.7 Rotate motor output shaft

WARNING: The rotor in this motor incorporates a Permanent Magnet (PM) design. When the rotor is rotated, a voltage is produced in the stator even when the motor is disconnected from a power source. Do not open electrical compartments or touch unprotected terminals while the rotor is turning.

Disconnect motor supply power and allow one minute for capacitors to discharge before servicing or replacing. Failure to comply with rotor safety procedures can cause serious injury or death and equipment damage.

Make sure all motor wire connections are properly terminated and insulated. Turn motor rotor (output shaft) by hand. It should turn freely with some drag from the bearing seals.

4.8 Ready spare storage

Motors purchased for ready spares are not placed into service immediately. These motors should be stored in a clean, dry space. Avoid spaces with large temperature swings to reduce condensation. Storage temperature is -40 to 185 °F (-40 to 85 °C).

Cover motors to prevent airborne dust and dirt particles. If the storage area location is prone to vibration, place vibration dampers under the motor base to prevent premature wear and damage to the bearings.

4.8.1     Motor bearings

The bearings used in this motor are lubricated and sealed at the factory. The motor does not require bearing lubrication in the field or during storage.

4.8.2    Scheduled output shaft rotation

WARNING: The rotor in this motor incorporates a Permanent Magnet (PM) design. When the rotor is rotated a voltage is produced in the stator even when the motor is disconnected from a power source. Do not open electrical compartments or touch unprotected terminals while the rotor is turning.

Disconnect motor supply power and allow one minute for capacitors to discharge before servicing or replacing. Failure to comply with rotor safety procedures can cause serious injury or death and equipment damage.

It is recommended that the rotor (output shaft) be rotated five to ten times every quarter (three months). This distributes grease in the bearings and reduces the chance of corrosion on bearing rolling elements and raceways. Bearing seals can add some resistance to turning the rotor.

 

5     Motor installation

5.1     Preparation

Review this entire manual prior to scheduling the motor installation. All equipment related to systems operation must be secured and have an active LOTO (Lock Out Tag Out) procedure in accordance with application specific safety policies. All users should be notified of the equipment outage.

5.1.1      Operating ambient temperature

The ambient temperature of the air supplied to the motor cooling inlet should not exceed 40° C (104° F) or be less than -25° C (-13° F). Power can be derated at higher temperatures by 2% per degree C up to 50° C. Use the Infinitum Motor Selection Tool to confirm derating details. Consult Infinitum for ambient temperatures not within these requirements.

Occasional start-up at temperatures below -25°C is permitted under certain conditions. For continuous operation at ambient temperatures below -25°C, special low-temperature bearings are required. Contact Infinitum for any application below -25°C ambient.

5.1.2     Ingress protection

Infinitum motor Ingress Protection (IP) ratings are identified by their respective nameplates. To maintain this IP rating, cable glands or seals must be used at all wiring ports and all gaskets in place with covers.

5.2 Mechanical installation

This section covers location, orientation, alignment, and mounting options for the Aircore EC+ motor. Dimensions for each frame size are included in the Appendix: Motor dimensions.

5.2.1      Location

WARNING: This motor is not certified to operate in any hazardous environments. Operating a motor in areas contaminated with explosive gases can cause explosions, resulting in serious injury or death and equipment damage.

• Electric motors have guidelines for their location and operating environment. These guidelines are listed below:
• The motor should be located in a ventilated enclosure and should be in an area that allows air circulation.
• Air cooling inlets and outlets must not be obstructed.
• The enclosure cannot be located in an area with harmful or explosive gases.
• The area should be free from dust and metallic particles.
• The motor should be easily accessed for cleaning and maintenance.

5.2.2     Orientation

Gen4 Aircore EC+ motors can be used in any orientation: horizontal, shaft up, or shaft down.

5.2.3     Mounting

The Aircore EC+ motor system is supplied with an integrated VFD.

The motor and drive are the major components of the assembly. Refer to Appendix: Technical specifications for a motor component drawing.

5.2.3.1      Mounting options

Driven equipment (for example, a fan wheel) should be mounted to the shaft using as much of the available shaft length as possible. A shaft key-way and shaft key are provided for secure coupling of hubs to the shaft.

There are two mounting options for the motor: peripheral mounting or C-face mounting.

a. Peripheral mounting block

There are four mounting blocks (if ordered) on the surface of the motor, spaced at 90º intervals (Figure 5). Each block has provisions for a lifting lug (eye-bolt) that can be used to lift the motor, and mounting holes at the drive end (DE) face and transverse surface.

The transverse face of the mounting block has threaded holes for four mounting bolts (M8X1.25). All four mounting bolts should be installed for secure motor mounting.

b. C-face mounting

Infinitum Aircore EC+ motors are not a NEMA standard frame size but utilize a NEMA 182TC faceplate mounting configuration.

The DE face of the mounting block has threaded holes for four bolts (M12X1.25). All bolts should be used for secure mounting of the motor to the equipment (Figure 6).

CAUTION: Use care when installing the driven equipment onto the rotor shaft. Do not force the hub or coupling onto the shaft, as this may damage the motor bearings. If the hub or coupling does not slide without resistance, check the alignment of the equipment with the rotor shaft.

Maintain adequate clearance between the front of the motor body and the equipment to prevent mechanical obstruction that may cause damage or injury.

The motor and stator assembly must be mounted on a structure that will support the operational weight of the motor and drive. Using vibration dampers at motor assembly mounts to reduce motor vibration is recommended. Align the motor output shaft centerline with the driven component and install mounting hardware, but do not tighten. This is completed by the alignment process.

5.2.4    Alignment

The motor may be directly mounted to equipment such as fan wheels or may be connected through a belt or pulley system. It may also be attached through a shaft coupling, e.g., to an independently mounted pump or to a torque meter in a laboratory setting. Ensure proper alignment is maintained in all arrangements.

Use the driven equipment manufacturer’s recommendations for aligning the motor with the fan drive or coupling. Tighten all bolts and nuts on the motor mount.

Motor rotation must be verified after electrical connection. Incorrect rotation can damage equipment.

5.3 Electrical installation

 

This section covers connection requirements, grounding, wiring guidelines, and control options for the Aircore EC+ motor.

5.3.1     Motor connection requirements

WARNING: Always disconnect power to the motor and practice all application specific safety procedures when installing, troubleshooting, or repairing a motor. Always verify power is secured with a multimeter prior to work. Failure to disconnect power from motors can result in serious personal injury or death and equipment damage.

WARNING: The rotor in this motor incorporates a Permanent Magnet (PM) design. When the rotor is rotated in a disconnected motor, voltage is produced. Do not touch unprotected terminals while the rotor is turning. Disconnect motor supply power and allow one minute for capacitors to discharge before servicing or replacing. Failure to comply with rotor safety procedures can cause serious injury or death and equipment damage.

WARNING: To reduce the possibility of personal injury or death and equipment damage, always make sure wire connections are secure and wires are in the correct location.

CAUTION: To prevent the possibility of motor damage, always use terminating ferrules for all supply wires. Terminating ferrules create a single connection point that is more secure than stranded wire.

Wire tensile forces can affect the point of termination during installation and motor operation. Terminal blocks with the correct wiring installed ensure safe motor operation. Using the correct wire gauge and amount of exposed conductor length with ferrules installed on each wire satisfies the requirements.

Make sure the source of power to the motor has been disconnected.

Strip wires and crimp on wire ferrules. Install each wire into the appropriate terminal block as provided in the wiring instructions. Verify all connections are tight and installed to specifications.

NEC 70 and NEMA MG2 standards should be followed for proper motor power wiring.

5.3.2    Motor control connections

Infinitum Aircore EC+ motors support the following standard industry control methods:

• Analog
• Modbus RTU
• BACnet MS/TP

5.4 Motor testing

This section covers testing the motor’s rotation and system operation when the motor is under load.

5.4.1     Check motor rotation

NOTICE: If the motor has been tested, and the technician has verified motor rotation prior to installation, the facility can elect not to perform this test because of redundancy.

Prerequisites: The motor has been installed, aligned, and electrically connected. The fan belt has been removed, or the coupling is disconnected. The motor must be briefly energized to check for proper rotation.

To check the motor rotation:

1. Review all installation instructions and all warnings prior to testing the motor.
2. Connect AC power.
3. Follow all safety precautions and energize the motor briefly to determine rotation. If the motor rotates opposite to the intended direction, switch the direction command utilizing the I-con control software tool.
4. Disconnect AC power.

5.4.2    Connect motor to driven equipment

WARNING: Always disconnect power and practice all safety procedures when installing, troubleshooting, or repairing a motor. Always verify power is secured with a multimeter prior to work. Failure to adhere to industry standard safety practices can result in serious personal injury or death and equipment damage.

Prerequisite: Motor rotation has been verified. The final series of steps will place the load on the motor and test system operation.

To test system operation:

1. Disconnect power from the motor.
2. Attach driven equipment confirming alignment.
3. Install all safety covers and connect power.
4. Start the system and verify that the motor operates properly.

6. Maintenance

WARNING: Always disconnect power and practice all safety procedures when installing, troubleshooting, or repairing a motor. Always verify power is secured with a multimeter prior to work. Failure to adhere to industry standard safety practices can result in serious personal injury or death and equipment damage.

Regular servicing and visual examinations, performed at the suggested intervals, will help maintain the motor’s performance and prevent potential issues.

6.1     Maintenance tasks

 

If the motor is operating in an environment susceptible to dust, dirt, corrosives, abrasive materials, or in an increased ambient temperature, use Table 3 to identify the level of severity and follow the recommended visual inspection frequency.

Maintaining this motor requires completion of both the visual inspection and the corrective maintenance tasks (if required). The basic tasks are outlined below. Visual inspection

1. Examine mounting structure and rotating equipment for loose components or damage.
2. Inspect the motor output shaft for damage. Replace damaged components and tighten any loose set screws.
3. Make sure the cooling fins of the heat sink and the area around the motor are free from dust and debris.
4. Verify that the mounting bolts and hardware are tight and secure.
5. If used, check rubber vibration isolators for cracks and damage.
6. Make sure all external wire connections are tight.
7. Inspect external wires for signs of heat or physical damage.
8. Make sure there are no unusual sounds coming from the rotating parts such as bearings.

Corrective maintenance

Any damage noted must be repaired before placing the motor in service.

1. If the access cover needs to be opened for further inspection, disconnect the motor line power and all associated motor operating equipment, and allow one minute for the motor capacitors to discharge.
2. Contact an authorized Infinitum representative for further investigation.

6.2 Mechanical issues

 

Problems with alignment can cause bearing wear. Lack of maintenance, improper installation, and loose mounting bolts can cause premature bearing wear and motor overload.

6.3 Windmilling

 

Infinitum Aircore EC+ motors can overcome “windmilling” (reverse rotation due to back pressure in HVAC applications) up to 200 RPM. In windmilling conditions under 200 RPM, the motor will stop reverse rotation and resume operations in the required operational direction. If the windmilling speed exceeds 200 RPM, alternative solutions are required, such as anti-windmilling devices like brakes, clutches, or louvers.

No operation via Modbus or Serial	Cable or Board issue	LOTO the motor at the mainline disconnect and follow your company procedure to ensure no power. Check L1, L2, L3 on the motor after LOTO to confirm no power. Are wires stripped properly and inserted into the terminal – Remove wires and re-seat to confirm. Review boards and wiring inside of motor access panel to determine if anything looks burnt, unplugged, or out of place. Contact Infinitum Support with any concerns. Pictures will help. MAKE SURE MOTOR HAS POWER REMOVED AND LOTO – Then physically spin motor to see if it spins freely. If there is resistance record it with a video and send to Infinitum Support. If motor spins freely then remove the CIO 24V DC Comm wires and use a meter to check them. Check all wires in the array of fans that are for the Modbus/ Comm. Confirm shields are terminated where needed, solid connections are made, and wires are not pinched/ nicked anywhere. It may be necessary to remove all connections and reset them back in the terminals/connectors. It is very important to have good connections on the Modbus/ Comm side. Make sure all motors in the array have the end of line jumper or end of line resistor installed per specs and only at the end of line. Confirm all motors that are not end of line motors have the comm dip-switch in the off position. Remove field wires for the Modbus Comm making sure the ends do not touch and are safely covered with tape or connectors. See Modbus RTU Troubleshooting Product Notice. Install wires from USB to RS485 adapter in the Comm ports. See if the motor will run using only the MCS and attached wires. If YES then there is a field wire issue. If NO then contact Infinitum Support for a new CIO board.
