In a dc motor the commutator is used to:
WebDevice used to change the DC into multiphase AC to produce a rotating magnetic field in the stationary armature of the brushless DC motor. Counter Electromotive Force (CEMF) (back-EMF) Voltage induced in the armature when the windings of the armature spin through the magnetic field produced by the pole pieces. WebSep 13, 2024 · An electronic controller replaces the commutator assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controllers used maybe MOSFET or IGBT and ESC. The controller performs similar timed power distribution by using a solid-state circuit rather than the commutator system.
