Abstract: A connector for an electric motor including a magnetic ring which is the seat of a magnetic field tied to operating parameters of the motor. A magnetic flux conduction member forms a flux concentrator interposed, when a connector is fixed on the motor, between the magnetic ring and a Hall-effect sensor to measure the magnetic flux conducted by the magnetic flux conduction member. The electric motor can be used with geared motors for window-lifting systems, seat actuation systems or sunroof systems in the automobile field.

Abstract: A system for controlling multiple vehicle includes a twelve volt (12V)/forty-two volt (42V) battery power distribution system that provides direct current. The system converts single phase alternating current to multiple phase alternating current to simultaneously power multiple vehicle systems. A single pulse width modulation generator converts the direct current from the 12V/42V battery power distribution system to alternating current. This provides one power supply path of alternating current, which has a first phase. A splitter device splits the one power supply path of alternating current into three power paths. A lead/lag circuit is used to shift the alternating current of the second path to a second phase different than the first phase of the first power supply path. A second lead/lag circuit for shifts the alternating current of the third path to a third phase different than the first phase or the second phase. This creates a three-phase alternating current power from a single direct current source.

Abstract: An AC motor is utilized to drive a closure on a vehicle. The use of the AC motor provides valuable benefits with regard to cost and size. Further, a three-phase AC motor may be utilized, and the pulses in its power supply monitored to determine an obstruction in the path of the closure. Frequency control may also be utilized to provide optimum control of the drive of the component at both start-up and stop.

Abstract: A plurality of motors for use in driving accessories on a vehicle, are each powered by three-phase current. A single controller controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source. A chopping circuit chops the voltage into a plurality of pulses, and a phase shift circuit then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.

Abstract: In the disclosed embodiment of this invention, sets of straight wire bundles are molded or otherwise encased about a cylindrical rotor casing. The straight wire bundles lie parallel to the axis of the cylindrical rotor casing. This process is an alternative to a traditional type of electric motor armature which uses a wire that is coiled around the cylindrical rotor casing. Since the wire bundles are straight and not pulled from a single wire roll, breaking and stretching of the wire is greatly reduced. The straight wire bundles are connected at their ends using a circuit cap to form a complete electrical circuit.

Abstract: A method of forming a relatively low cost motor provides a motor rotor and/or stator which has a generally solid body. The core of the body is formed of a less conductive material, and a more conductive material is at circumferentially spaced locations on the core. In one embodiment, the conductive material and the less conductive material are co-extruded. In a second embodiment, the core material is formed by powdered metal technology, and the conductive material is deposited onto the core.

Abstract: The process comprises forming a tube (1) of an electrically conductive material having on its inner surface axial grooves (2) and axial projecting portions (3) between the latter, injecting a hardenable insulating material (4) into the tube (1) so as to fill the latter, this material penetrating the grooves and surrounding the projecting portions, and removing the outer portion of the tube (1) after the hardening of the insulating material so as to reveal the insulating material of the grooves (2) and form between the latter commutator segments which are insulated from one another. The tube (1) is formed by the extrusion of two complementary half-tube shells (1a, 1b) and the assembly of the latter one against the other on an axial joint plane (A--A).
