DC motor Torque

Postby tjanggut » Wed Apr 13, 2011 1:43 pm

Hi there,
I was assigned to make a project that can variable a DC motor torque using micro-controller (whatever type).
my question is:

1- Is it possible we can variable a DC motor torque? or we need a AC motor?
2- Is it PWM can variable DC motor torque? because before this i just use the PWM to control speed of DC motor.

I hope somebody can help me. :D

It's possible. PWM duty cycle is controlling speed, PWM frequency is controlling torque. You may test it.
