Abstract: A bearing lock is provided that improves upon existing methods of stabilizing a bearing in an electric motor. The bearing is fit between a rotatable shaft and a nonrotating annular support. The bearing has an inner race surrounding the rotatable shaft and has an outer race surrounded by the annular support. The bearing lock has an annular body with a midportion, an inner wall, and an outer wall. Both the inner wall and the outer wall extend generally in a first direction from the midportion and are spaced from one another to define an annular cavity therebetween. The outer wall has circumferentially-spaced integral tabs that extend at least partially toward the inner wall to provide a biasing force to lock the body to the annular support when the annular support is placed in the annular cavity.

Abstract: A motor includes a stator including windings and leads extending from the windings. A rotor is in magnetic coupling relation with the stator and electronic components are electrically connected to the leads. An actively cooled shield separates the electronic components from the rotor and stator. The winding leads are thermally connected with the shield for transferring heat from the winding leads through the shield so that heat transferred from the winding leads to the electronic components is reduced.

Abstract: An electric motor assembly includes a motor shaft rotatable about a longitudinal axis, an angular position sensor, and a deformable pin. The motor shaft has an axial keyway formed therein, and the axial keyway has a nominal keyway dimension. The angular position is coupled to the motor shaft to rotate with the motor shaft. The angular position sensor has an axial key to fit within the axial keyway of the motor shaft, and the axial key has a nominal key dimension that is less than the nominal keyway dimension. The deformable pin is located in the axial keyway under compression between the axial key and the motor shaft to inhibit rotational shifting of the angular position sensor relative to the motor shaft.

Abstract: The present invention comprehends a gerotor or gear pump driven by a permanent magnet motor which exhibits cogging torque, i.e., resistance to rotation when de-energized caused by interaction between permanent magnets in the rotor and teeth on the stator. Such interaction causes the rotor to come to rest in one of many defined rotational positions and resist rotation when electrical power to the motor has been terminated. The permanent magnet motor is coupled, preferably directly, to a gerotor pump having meshing rotors or a gear pump having meshing gears. When the motor is de-energized, the pump rotors or gears come to rest and their rotation is resisted by the cogging torque of the motor. The invention finds particular application in automotive transmissions and systems with parallel pumps.
