Brushed DC Motor Fundamentals
Brushed DC motors are widely used in applications ranging from toys to push-button
adjustable car seats. Brushed DC (BDC) motors are inexpensive, easy to drive,
and are readily available in all sizes and shapes. This application note will
discuss how a BDC motor works, how to drive a BDC motor, and how a drive circuit
can be interfaced to a PIC® microcontroller.
