Hi everyone! I use ST Motor pilot to control the motor. The motor reference is 354 RPM. Quantity of pole pairs is 10. Phase period must be 60 / (354 * 10) = 17 ms. But when I display the electrical phase plot, I see that the period of the phase is 136 units. What do these units mean? ms or us?

Hello,
Samples rate is (PWM Periode)*(execution rate). E.g for a PWM frequency 20kHz and Execution rate 2, sample are at a rate of 100us/units.
Best regards.
