Abstract
A control device-integrated rotary electric machine that has a light weight and a small radial-direction dimension. A cylindrical member is provided between a stator formed by stacking electromagnetic steel sheets and a frame retaining the stator, such that the cylindrical member is in a press-fitted state against the stator and the frame. The cylindrical member has a flange portion at one end thereof, and the flange portion is fixed by being held between the frame and a heat sink which is a member composing a control device.
Claims6
A control device-integrated rotary electric machine comprising:
- a rotor fixed to a rotor shaft;
- a stator formed by stacking electromagnetic steel sheets, and provided so as to be separated from the rotor and surround the rotor;
- a stator winding wound on the stator;
- a cylindrical member provided in contact with the stator;
- a frame provided in contact with the cylindrical member and retaining the stator;
- and
- a control device having a heat sink in contact with an inner side of the frame, and configured to supply power to the stator winding, wherein
- the cylindrical member has a flange portion at an end thereof,
- the flange portion is held between the frame and the heat sink so as to be fixed in an axial direction, and
- the flange portion is formed over an entire circumference at the end of the cylindrical member.
