Abstract: An armature which radially faces a magnetic field-producing unit equipped with a magnet unit having a plurality of magnetic poles includes a housing, an armature core, a multi-phase armature winding, and bus bars. The housing includes a cylinder and a disc-shaped end plate placed in contact with one of axially opposed ends of the cylinder. The armature core is disposed on a portion of the cylinder which radially faces the magnet unit. The armature winding is disposed on a portion of the armature core which radially faces the magnet unit. The bus bars electrically connect phase windings of the armature winding together. The armature also includes a bus bar module which is of a circular or C-shape extending along the circumference of the armature core. The bus bar module is secured to the cylinder, the end plate, or one of axially opposed ends of the armature core.

Abstract: In a rotating electrical machine, a holder member is disposed to be radially closer to an armature coil than to a magnetic field generator. The holder member is configured to hold the armature coil. The holder member has a first portion that faces a first end portion of the armature coil, and a second portion that faces a second end portion of the armature coil. The first portion of the holder member is thermally coupled to the first end portion of the armature coil. The second portion of the holder member is thermally coupled to the second end portion of the armature coil.

Abstract: 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. This minimizes adverse effects of magnetic flux, as generated by the rotating electrical machine, on operation of the angle position sensing device, thereby enhancing a measurement accuracy of the angle positon sensing device.

Abstract: A controller integrated rotating electrical machine is designed to minimize adverse thermal effects on a control device. The controller device includes switching modules, a control circuit, and a casing. The switching modules are disposed inside the casing at a distance from a rear housing. The control circuit is disposed in the casing and located in front of the switching modules at a distance from the rear housing and the switching modules. In other words, the control circuit is arranged away from the switching modules which are a heat source when operating, thereby eliminating adverse thermal effects on the control circuit.
