they call me frenchy!
Howdy,
I have an application where I am designing a simple speed controller
for a 12VDC brush motor (pump). The motor draws approx 6 amps
continuous when running, depending on the load. I have the electronic
schematic all nailed down for driving the pump, but I need to set the
optimum PWM frequency for the motor that I am using. Can anyone refer
me to a nice text that discusses optimum PWM frequency choice for
optimum efficiency, etc. I assume that it is dependent on the motor
inductance, etc and I would like to research this matter fully. I've
found a few texts that touch on the topic, but none that delve into
it.
Any suggestions would be appreciated.
Thank you,
frenchy
