Mechanically and electrically integrated rotary electric machine
First Claim
1. A mechanically and electrically integrated rotary electric machine comprising:
- a cylindrical frame;
a motor portion comprising;
a cylindrical stator core;
a plurality of coils that are disposed around an inner circumference of the stator core; and
a rotor that is rotatably disposed inside the stator core,the motor portion being inserted inside the frame;
an inverter portion comprising a plurality of switching elements, the inverter portion being fixed to an inner circumferential surface of the frame; and
a connector that electrically connects the coils and the switching elements,wherein the connector comprises;
an end portion connector that is disposed on an end portion of the motor portion near an output shaft, and that distributes sinusoidal electric currents from the switching elements to each of the coils; and
a plurality of axial connectors that are disposed so as to pass from the switching elements through a mounted region of the motor portion parallel to an axial direction of the frame, the axial connectors directing the sinusoidal electric currents from the switching elements to the end portion connector.

Abstract
In a mechanically and electrically integrated rotary electric machine, a motor portion and an inverter portion are inserted inside a cylindrical frame. The motor portion has a plurality of coils. The inverter portion has a plurality of switching elements. The coils and the switching elements are electrically connected by a connector. The connector has: an end portion connector that distributes sinusoidal electric currents from the switching elements to the respective coils; and a plurality of axial connectors that direct the sinusoidal electric currents from the switching elements to the end portion connector. The end portion connector is disposed on an end portion of the motor portion near an output shaft. The axial connectors are disposed parallel to an axial direction of the frame so as to pass from the switching elements through a mounted region of the motor portion.
