More Information
Summary:An external rotor motor includes an inner stator and an external rotor. The inner stator includes a stator yoke and stator windings. The stator yoke has a first side and a second side opposite to each other. The first side and the second side are in an axial direction of the inner stator. The stator windings wound round the stator yoke. The external rotor includes a case and a magnet. The magnet is disposed on an inner side of the case, the stator yoke is surrounded by the magnet. The external rotor is rotatable to the inner stator. Two sides of the magnet opposite to each other respectively protrude from the first side and the second side of the stator yoke, and a center of the stator yoke and a center of the magnet are spaced apart by a distance in the axial direction of the inner stator.
