An endplate for attachment to a stator frame of an electric motor used to drive an air compressor. The air compressor has a crankshaft rotationally supported by at least one rotational bearing, and the electric motor includes the stator frame, a stator element mounted to and within the stator frame, and a rotor element rigidly mounted on a portion of the crankshaft for rotation therewith. The crankshaft projects through the stator element and terminates in a distal end. The endplate is adapted for mounting to the stator frame so as to provide support for mounting an additional rotational bearing for rotationally supporting the distal end of the crankshaft on an opposite side of the rotor from the at least one rotational bearing. The endplate includes a cap member and an attachment mechanism for attaching the cap member to the stator frame, the cap member including a rotational bearing housing for mounting and positioning a rotational bearing thereon and the rotational bearing housing being substantially positioned in juxtaposition to the distal end of the crankshaft when the cap member is attached to the stator frame by the attachment mechanism.Also disclosed is a kit for retrofitting an electric motor driven air compressor so as to provide the electric motor driven air compressor with such an outboard rotational bearing.
