Re: Are motor speeds proportional to PWM value?
Just a little correction here... the PWM signal will pulse the voltage.
The voltage does not change it is pulsed to achieve the speed you desire from the motor.
PWM control (Pulse Width Modulation) varies the width of these pulses of voltage (presumably at 12 V) to achieve this control.
The motors see the same voltage at all times...
This is different than a "dimmer" type of motor controller .... which actually varies the voltage in order to speed up or slow down the motor.
This is inherently inefficient because the lower voltage will provide less power along with the slower speed. We want to maintain the power, by using the same voltage at all times.
If you google Pulse Width Modulation it will tell you all about it.
good luck this year!!
