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
