What is meant by brushless DC motor?
A brushless DC motor is essentially flipped inside out, eliminating the need for brushes to flip the electromagnetic field. In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator.
A brushless DC (BLDC) motor, also known as an electronically commutated motor (ECM), is a type of electric motor that uses electronic commutation instead of mechanical commutation to control the speed and direction of the motor.
In a brushless DC motor, the rotor consists of permanent magnets, while the stator has the windings. The windings are energized in a specific sequence by the motor controller, which determines the direction and speed of the motor. The motor controller uses feedback from sensors, such as hall effect sensors or encoders, to accurately control the position and speed of the rotor.
Compared to brushed DC motors, brushless DC motors offer several advantages, including higher efficiency, higher power density, longer lifespan, and less maintenance. They are commonly used in various applications, including drones, electric vehicles, robotics, and industrial machinery.
