An Inexpensive Imbedded Motor Controller Using a Tachometer Feedback

摘要

This paper describes a DC motor drive using a pulse width modulated (PWM) signal and tachometer feedback. The PWM and analog-to-digital capabilities of a microcontroller are used to realize a very inexpensive and efficient controller. The design of the entire system, as well as PCB layout are explored. Manufacturing considerations for the entire system are also presented.
