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.
