What is a BLDC outrunner motor?

The rotor of a bldc outrunner motor is located outside the motor, while the motor stator is fixed inside. The motor is commutated and controlled by an electronic controller.

 

1.Outer rotor design

  • Structural features:  The rotor of bldc outrunner motor surrounds the stator to form a ring structure. The outer rotor design means that the motor can use more magnets, resulting in a greater moment of inertia.

2.Brushless technology

  • Electronic commutation: Same as brushless motors, outer rotor motors use electronic controllers to achieve commutation, providing more precise and efficient current control.
