Permanent Magnet Synchronous Motor (PMSM) Technology

Each TKH synchronous torque motor is based on a
permanent magnet synchronous motor (PMSM) architecture, ensuring
high torque density, low cogging, and smooth torque output.

The PMSM torque design guarantees constant performance
and superior energy efficiency across a wide speed range.

Thanks to their AC synchronous motor operation, TKH motors deliver
accurate torque control and minimal energy losses, even under dynamic load conditions.
