Re: Are motor speeds proportional to PWM value?
In general, no. The PWM value is proportional to the (average) voltage coming out of the speed controller. The motors voltage/RPM curve is not very linear and it depends on the torque on the motor, amperage it can draw and perhaps other factors. If you put an encoder on your motor, you could plot this PWM/RPM graph and see what the curve looks like.
