Abstract
An electric motor includes a stator, a rotor, and weights removably attached to the rotor shell for use in balancing the rotor. The removable weights may be integrally formed with a rotor shell such that the weights and the rotor shell form a unitary, one-piece construction. The removable weights may be substantially uniformly spaced apart around an entirety of the outer perimeter of the rotor shell. In a method of making an electric motor, the stator is coupled to the rotor such that the weights are accessible for selective removal during balancing of the rotor.
