KMF Frameless Direct Drive Torque Motor

Ref: KMF

KMF high-torque frameless direct drive motors have high torque output and torque density. They also have ultra-low cogging torque, extremely low torque fluctuation at low speed, low noise, and precise rotation movement for efficient and stable solutions required by the mechanical system.

The KMF high-torque frameless direct drive motor adopts high-power-density windings for applications requiring small and compact size, low weight, and low inertia. The high-performance NdFeB rotor and carbon fiber material wrap design provide efficient and stable solutions for the system.

Leaderdrive is a recognized provider of high-precision frameless motors. We provide a range of services to ensure that our products can be applied in any situation. Contact us to discuss frameless motors with custom specifications or to request detailed performance data.
