BRUSHED DC MOTOR CONSTRUCTION AND PERFORMANCE


-
Easy to predict motor performance
-
Simple, inexpensive control electronics
-
Use of a feedback device is optional
-
Difficult to design brush system
-
Limited availability of the brush system components
-
Very difficult to predict brush life
-
Not a motor of choice for high-performance application
-
Manufacturing cost very low for mass production, when fully tooled
