Outer Rotor Brushless DC Motor 90mm

Product Description

Compared with the inner rotor motor, the flat outer rotor brushless motor has a more compact structure and lower torque ripple.
Under the same volume, the outer rotor brushless motor will output a greater torque than the inner rotor motor.The 42mm outer rotor brushless DC motor can be applied to robot, AGV, turnstile, coffee maker and so on.

Ability

What is the outrunner BLDC motor?

The internal rotor motor is the motor that the rotor rotates with a motor spindle. The motor frame is fixed, the shell is as the stator, and the internal and spindle as the rotor. The external rotor motor is that the rotor rotates with housing, the motor spindle is fixed, the internal and spindle are as the stator.
