Gigi:
I have a question, measured in workbench Motor Electrical parameters Rs and Ls. I see ST data is used RLC meter measurement frequency at 100 Hz, but the motor is running in the PWM 16K frequency, whether I used RLC meter frequency measurement of 10K or 100Hz? Because both the difference between the value of high. And RS is using a multimeter to measure, or with the corresponding RLC frequency? Best Regards Jacky2014-10-22 12:04 AM
Ciao Jacky
The point is that you need to measure the Ls at the electrical frequency of the motor (that usually is in the range of undreds of Hz) and not the Ls at the PWM frequency. Ciao Gigi2014-10-22 09:34 PM
