Abstract
An electric motor includes a stator and a rotor assembly received in the stator. The rotor assembly includes a rotor body having a lamination stack, and an integral fan and magnet retention formed by molding an insulative material to the lamination stack. The rotor assembly also includes a shaft pressed into the rotor body. The shaft is pressed into the rotor body after the insulative material is molded to the lamination stack to form the integral fan and magnet retention.
