The same PWM control used on charge controllers is also used on electric
vehicles for DC motors. We've done many different ones and different
voltages and sizes.
Something like this might work:

Hey Folks....we have a customer with a 24VDC fan for venting a
green house and we would like to be able to control speed on it
instead of just on/off...The fan draws 22 Amps at 24VDC....Any
suggestions on how to regulate speed? The idea is to have the fan
pull less than the 22 amps............
rheostat? potentiometer....
I think essentially what i am looking for is a dimmer switch for a
24VDC motor.....
Thank you!!
