 |
|
Can any one tell if the duty cycle on a PWM will equate at least roughly
with motor speed? ie will a 20% duty cycle slow the motor down to
approximately %20 or does it not work that way? I have a linear actuator for
pitch trim that that travels 2"/sec, I need about .5"/sec.
Thanks, Tim Andres

MPJA sells a motor control unit that does exactly that and at just over

$12, I don't think you can beat the price.
