The electronic commutated motor is which type?

The electronic commutated motor is which type?

• A. Alternating current (AC) motor
• B. Direct current (DC) motor
• C. Synchronous motor
• D. Stepper motor

Answer: (B)

Electronic commutation means switching the motor windings with electronics rather than with brushes and a mechanical commutator. That’s the defining feature of brushless DC motors. So an electronically commutated motor is a DC motor that is energized by an electronic controller, which sequences the windings to create a rotating magnetic field while the input remains DC. This contrasts with AC motors, which run directly from alternating current, and with other motor types that don’t rely on electronic commutation. The term essentially points to a brushless DC motor.
