How to contol speed of DC motor with PWM
How to contol speed of DC motor with PWM
(OP)
I have project to build centrifuge with motor dc, but i have problem with speed control with PWM. I need max 3000 rpm and i use encoder for to know how many rotation and position. But i don't how to integrated with microcontroller. Can I use PWM chip?
Please reply to me dee2jee@yahoo.com

has an app. note on motor control. Pick a micro that your
comfortable with. I like TI or Microchip.Most have built in
PWM's.

What is the RPM accuracy you need to attain ?.
Question what is the power of the motor and the voltage.
How many are you going to build ?.
If you need more info let me know.
