FAQ

How does a brushless motor work?

A brushless DC motor uses electronic commutation instead of brushes.
Hall sensors detect the rotor position, and the controller switches current
through the stator windings to generate a rotating magnetic field that drives
the rotor.

Brushless DC motor vs brushed DC motor

Compared with brushed motors, BLDC motors provide higher efficiency, longer life,
lower maintenance, and reduced electrical noise due to the absence of brushes.

Brushless DC motor and controller

A BLDC motor requires a dedicated brushless DC motor driver or controller
to manage commutation, speed control, and torque regulation.

Brushless motor speed controller

A brushless motor speed controller regulates the voltage and commutation sequence
of the motor phases to precisely control the rotational speed and torque output.
