{{id}} {{{paragraph}}}
2010 Microchip Technology 1AN905 INTRODUCTIONB rushed DC motors are widely used in applicationsranging from toys to push-button adjustable car DC (BDC) motors are inexpensive, easy todrive, and are readily available in all sizes and application note will discuss how a BDC motorworks, how to drive a BDC Motor , and how a drivecircuit can be interfaced to a PIC OF OPERATIONThe construction of a simple BDC Motor is shown inFigure 1. All BDC motors are made of the same basiccomponents: a stator, rotor, brushes and a following paragraphs will explain each componentin greater stator generates a stationary magnetic field thatsurrounds the rotor.
Brushed DC (BDC) motors are inexpensive, easy to drive, and are readily available in all sizes and shapes. ... Brushed DC Motor Fundamentals. AN905 DS00905B-page 2 2010 Microchip Technology Inc. Brushes and Commutator Unlike other electric motor types (i.e., brushless DC,
