Brushless DC Motor

A brushless DC motor is a synchronous motor that uses a direct current (DC) power supply. It is also called an electronically commutated motor (ECM or EC motor) or a synchronous DC motor. ‌This motor converts the DC power supply into a three-phase AC power supply through an inverter and is a permanent magnet synchronous motor with position feedback. The brushless DC motor uses an electronic commutator to replace the traditional mechanical commutator, so it has many advantages, such as high efficiency, low noise, long life and no sparks.
