Integrated Permanent Magnet Synchronous Motor (PMSM)

This is a tiny but powerful permanent magnet synchronous motor. It fits into very tight spaces. On the back, a single PCB combines the driver and the encoder. This means you don’t need a separate drive board or extra wiring. A simple connector makes installation quick and easy. This motor is a great choice for robot joints, grippers, medical devices, and lab equipment. Anywhere you need small size and smooth, precise motion, this motor can help.

Direct drives need high-quality position signals to ensure optimal performance. Perfect measuring signals can enhance the surface quality of machined workpieces, reduce the machine frame's vibrations, minimize velocity-dependent motor noise, and prevent excessive heat generation in the motor.

Mosrac recommends using a magnetic encoder to enhance the accuracy, speed stability, and thermal behavior of direct drive axes. Because there is no mechanical transmission between the encoder and the feed unit, the position signals are not susceptible to inaccuracies or delays.

Custom combinations are available on request and contact us.
