Motor and drive all in one
Integrated variable frequency drive (VFD) facilitates variable speed applications, reducing overall energy usage.
Power more with less
50% lighter, 30% quieter and up to 25% more efficient, averaging $2,300 in energy savings per motor.*
Powerful intelligence
- State-of-the-art VFD for precise speed control which contributes to energy and audible noise reduction.
- I-con motor control software enables users to fine tune operational parameters to their specific applications.
- Maximum power density in a 50% smaller and lighter package.
Optimized efficiency
- Meets highest efficiency standards at a wide range of operating conditions.
- Increased operational efficiency by eliminating torque ripple, cogging, stator hysteresis and eddy current losses.
- Compact form factor reduces wiring and facilitates direct mounting to fan applications, increasing efficiency by up to 25% compared to a traditional motor.
Sustainable solution
- Our PCB stator uses 66% less copper and is 10x more reliable than traditional iron-core, copper-wound stators.
- Enhanced serviceability due to modular design enables the reuse and extended lifespan of components, keeping them out of the landfill.
- Increased efficiency reduces customer’s scope 2 emissions by up to 25%.

Recommended operating range
Note: Infinitum does not recommend using the motor below 60% of rated speed at full torque except when coasting or ramping up. It is also essential to restrict power and FLA within the nameplate rating when operating the motor above 100% of its rated speed. To operate the motor outside the recommended operating range, please contact the factory and our Application Engineers will provide a customized solution.
