Brushless DC electric motor - Wikipedia
WEBA brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
BLDC Motor Controller: Design Principles & Circuit Examples
WEBFeb 25, 2021 · BLDC Motor Controller Circuit Design. A typical BLDC motor controller has a half-bridge or half-H bridge circuit. Unlike an H bridge, this circuit configuration has only two switches - one high-side and one low-side transistor. Most brushless motors use two or three-phase power systems.
