Abstract: A number of embodiments of rotating electrical machines and methods for winding them that provides a high space utilization and very effective winding with less likelihood of damage to the insulation of the wire of the winding during the winding process. The arrangement basically does not require the winding needle to be moved back and forth in the slot between the poles but rather employs insulating inserts that are positioned on the axial faces of the poles outside of the gaps for guiding the wire from one end to the other so as to provide the high space utilization. In one embodiment the insulating insert effectively changes the circumferential length of the coil winding that decreases in an axial direction along their length.

The large current terminal unit and a magnetic pole position detector are located on opposite sides of the stator, with the former mounted on one end of the shaft of a cooperating rotor and with the other on the other end of the rotor shaft, and they are fixed in solidified molding resin to form a single body.

Abstract: A rotating electrical machine such as electrical starter motor and more particularly to an improved method and apparatus for winding the armature coils of a rotating electrical machine. The winding apparatus and method is particularly adapted for use with large diameter wires and permits winding without a winding needle having to pass into the slot between the pole teeth. This is accomplished by introducing some slack in the wire by moving the wire in a circumferential direction when the winding needle is not disposed in proximity to the slot and then returning the winding needle to registry with the slot.

Abstract: An ignition control circuit and method of operation provides a very simple but highly effective prevention of engine reverse rotation upon starting by prohibiting ignition when a reverse rotation situation arises.

Abstract: Two embodiments of winding methods and apparatus for winding coils of a rotating electrical machine where the armature teeth are skewed. The winding mechanism and method operates so that the winding needle does not have to enter to the bottom of the slots between the pole teeth but the wire is wound around the pole teeth from one end thereof with an arrangement for causing the windings to progressively move down the pole teeth as the winding continues.

Abstract: An apparatus and method for forming cylindrical magnetic assemblies for rotating electrical machines. The apparatus and method pre-bends and finally bends a flange of the supporting shell to lock the permanent magnets in place. This is done in a single station and in two steps by way of an apparatus that permits handling of cylindrical bodies of considerably different diameters and lengths.

Abstract: Several embodiments of laminated cores for coil winding in rotating electric machines. In each embodiment, the laminations are formed with indented portions in an area where the flux pattern will not be disturbed with the indentation serving the purpose of aligning the sheets of the laminations with each other. In preferred embodiments, the indentations are formed in the peripheral edge of the circular core portion from which the pole teeth extend.
