Abstract: An electric motor includes a stator assembly and a rotor assembly. The rotor assembly includes a rotor shaft that is rotatable relative to the stator assembly about a rotation axis. The motor also includes an endshield, a bearing assembly rotatably supporting the rotor shaft on the endshield, a shaft ground assembly electrically coupled to the rotor shaft, and a bearing lockplate. The bearing lockplate is fixedly coupled to the endshield. The shaft ground assembly is supported by the bearing lockplate on the endshield.
