Lenze MF Motors: The Hybrid Power Solution for High-Speed Industrial Applications

Introducing the Lenze MF Motor


In today’s manufacturing environment, engineers need solutions that balance performance, efficiency, and flexibility. The Lenze MF motor delivers exactly that—a motor designed as a hybrid between a traditional 60 Hz induction motor and a servo motor.


This inverter-duty motor operates at frequencies up to 120 Hz, providing constant torque from 5 Hz to 120 Hz. The result is high-speed capability without torque loss, making it ideal for applications where speed and precision go hand in hand.

 

Performance Highlights

  • Constant torque from 5 Hz to 120 Hz
  • Horsepower range: 3⁄4 HP to 30 HP
  • Encoder feedback options: resolver, absolute, incremental
  • Scalable braking and thermal sensors
  • Compact design: about one-third the size and weight of a standard motor
  • Efficiency: between IE2 and IE3 classifications
    Because of its 24:1 speed range without field weakening, a single Lenze MF motor can
    replace multiple conventional motor sizes. This reduces SKUs, inventory costs, and
    engineering complexity—while increasing design flexibility.

 

Engineered for Modern Automation

The MF motor represents Lenze’s commitment to smarter motion control. By combining servo-like responsiveness with the simplicity of an AC induction motor, it achieves a rare balance between dynamic performance and straightforward operation.

 

Every component—windings, shaft seals, and bearings—has been optimized for higher frequencies and longer service life. The result is a motor that keeps pace with today’s high-speed conveyors, packaging equipment, and material-handling systems while minimizing maintenance needs.

 

Applications That Benefit from MF Motors

Lenze MF motors shine in industries where precise speed control and compact design is
essential:

  • Turntables and rotary indexers
  • Automated storage and retrieval systems
  • Conveyors and packaging lines
  • Rapid-action doors
  • Sanding, polishing, or deburring machines
  • Pumps and fans
    For any system operating above 1800 RPM, upgrading to an MF motor can reduce the required horsepower—leading to long-term energy and cost savings.

 

Pair the MF Motor with Lenze Drives and Gearboxes

To maximize performance, the MF motor is designed to pair seamlessly with Lenze i500 series of variable frequency drives and Lenze gearboxes.

 

  • Lenze i500 drives provide smooth speed and torque control, with motor-mounted
    options for streamlined integration.
  • Lenze gearboxes achieve high ratios—up to i = 60—thanks to their direct-mounted
    pinion design, delivering compact and efficient motion systems.
    Together, these products form a complete Lenze motion solution, boosting productivity
    and offering a clear competitive advantage for OEMs and system integrators.
