Publication number: 20170346429Abstract: A controller-integrated rotating electrical machine incudes a rotating electrical machine and a control device. The rotating electrical machine is equipped with a stator and a rotor. The control device is equipped with a control circuit for an inverter circuit and an angle position sensing device which works to measure an angular position of the rotor. The control device has first substrate on which the control circuit is mounted and a second substrate on which the angle position sensing device is mounted. The first substrate is located closer to the rotating electrical machine than the angle position sensing device is in an axial direction of the controller-integrated rotating electrical machine.
