Abstract
A rotor is provided for an electric motor. The rotor shaft is located within a central opening of the rotor core. The central opening is sized larger than the rotor shaft such that a circumferential gap exists between the rotor core and the rotor shaft while the shaft is located by protrusions in the central opening of the rotor core. The circumferential gap is filled with a resin.
