Sensless position control FRDM-KV31F

andreaswickstrom — Sun, 08 Jul 2018 20:58:47 GMT

Is there any example where i can use a pmsm motor and position control with the FRDM-KV31F board?

I can run the sensless velocity but i cant find any example with go to angle.

I use a motor with a gearbox connected to it.

Best regards

Andreas

Andreas,

Kinetis Motor Suite includes a sensored position control reference project. This project requires the use of an encoder attached to the motor. Sensorless control isn't good enough at low speeds to support sensorless position control.
