hi folks
just when i was trying to control my dc motor by a pwm signal, i simply couldn't figure out the ideal frequency at which dc motors should be controlled..
and hows the frequency related to the speed of motor b'coz i guess its duty cycle which decides the speed at which the motors is moving.
when i gave 50% 38khz..motor was moving fine at a voltage supply of 10 volts
but when i gave 25khz ...it moved and stopped aftr sometime..
what is the reason?
thanks in advance
