Latest Patents
Ichikawa's latest patents include a manufacturing method of a stator for vehicular rotary electric machines. This innovative method involves forming an indentation in a radial direction in the side face of each electrical conductor by pressing. The electrical conductors are then inserted in a radially side-by-side relationship within the machine's slots. Each conductor is bent in different circumferential directions, allowing the indentations to pass each other in a face-to-face relationship. This method enhances the bonding process between adjacent electrical conductors.
Another significant patent is for an automotive alternator that features a cooling fan coupled to the rotor shaft. This alternator design includes a stator supported between a front and rear housing, with a rotor connected to a rotor shaft. The cooling fan is strategically positioned at the end of the pole core of the rotor and is coupled to the rotor shaft without the need for a jig. This design effectively suppresses noises and vibrations caused by rotational imbalance.
