ABSTRACT:
A motor, described as a brushless permanent magnet (BPM) motor, has a cup-shaped, open bottomed enclosure having a side wall and a top wall defining a lower interior space. The side wall has a port interrupting a bottom edge. A printed circuit board or other motor electric circuit is positioned above the top wall, below the stator. Electrical conductors electrically connected to the electric motor circuit extend through the top wall and into the interior space. Current supply conductors extend through the side wall port and are electrically connected to the electrical conductors from the circuit. An enclosure cover member has, projecting into the interior space, at least one deflectable prong with an overhanging lip, and a strain relief block positioned adjacent but spaced from the side wall port. The cover has a tool-receiving aperture to permit engagement of a tool with the prong. A ledge, carried by an inner surface of the enclosure, is positioned complementarily to the prong lip to permit the lip to engage a surface of the ledge remote from an inner surface of the cover to hold the cover in position, but to permit the displacement of the prong by a tool inserted through the cover aperture to release the prong and the cover. In the illustrative embodiment, conductor wires from a circuit board mounted above the top wall are mounted in a connector block within the enclosure, and the lip-engaging ledge is part of the connector block. The enclosure and the cover preferably are constructed from electrically insulative material.
