pwm dc drive
Hello,
I am driving a 24VDC permanent magnet DC motor with a PWM drive. Maximum current is around 2 Amps
However I am not sure how to arrive at the frequency of the PWM pulses. I am sure that the frequency does have a effect on the torque characteristics - I am currently using around 1Khz.
Is there any empirical formula or guideline for this ?
Thanks
Raghu
