An insertion groove is disposed on a tubular portion overlapping portion that is overlapped with an inner circumferential surface of a tubular portion of the stator core. Inter-coil insulating bodies that are disposed between a plurality of stator coils include a groove inserted portion. The groove inserted portion includes: a first inserted portion that can be inserted inside the insertion groove when the insulating film is in a bent and folded state; and a second inserted portion that is contiguous to the first inserted portion, a shape of a visible outline of a cross section of the second inserted portion being different than that of the first inserted portion. The second inserted portion generates a stronger elastic force of recovery than the first inserted portion when the groove inserted portion is inserted into the insertion groove.

In a motor, a magnet is configured so that four pairs of S-poles and N-poles are formed at equal angular intervals, and a stator core has six salient poles formed thereon. Of the plurality of salient poles, when the first salient pole or the second salient pole faces a position between an S-pole and an N-pole, the other salient pole faces the center of an S-pole or the center of an N-pole. The radial-direction lengths of the first salient pole and the second salient pole among the plurality of salient poles are longer than the other salient poles, and the radial-direction length of the portion of the first coil wound around the first salient pole and the radial-direction length of the portion of the second coil wound around the second salient pole are longer than the radial-direction lengths of the other salient poles.

A drive assembly having an electric motor, having a stator housing, a stator accommodated therein and having at least one winding, a stator insulation which has a lower part and an upper part, wherein the lower part rests against at least one bearing surface in the stator housing, terminal contacts for the winding, wherein the terminal contacts are held in a contact carrier, which is provided on the lower part of the stator insulation, and a printed circuit board, which rests on at least one supporting surface in the stator housing, wherein the terminal contacts are in contact with associated conductor tracks of the printed circuit board.

A rotor for a rotating electric machine includes a field core having a plurality of claw-shaped magnetic pole portions, a field coil wound on the field core, and a hollow cylindrical core member disposed to cover radially outer peripheries of the claw-shaped magnetic pole portions of the field core. The core member has a plurality of first electrically-insulating portions that are spaced at first intervals in an axial direction of the core member. Each of the claw-shaped magnetic pole portions of the field core has a radially outer peripheral surface abutting the core member and a plurality of second electrically-insulating portions provided on the radially outer peripheral surface. The second electrically-insulating portions are spaced at second intervals in the axial direction of the core member.

A stator includes layers of coated conductor. The coating is insulative and provides electrical isolation of adjacent conductor layers. The multiple layers of coated conductor form a stator core, and the stator includes magnet assemblies that sandwich the stator core. The conductor layers stack in a direction orthogonal to a plane of the magnet assemblies. The conductor layers have a rectangular cross section.

A coil bobbin for a brushless alternator includes an integrally formed one piece bobbin body that has a first end, a second end and a central passage that extends from the first end to the second end. A coil support portion of the body is positioned at the first end and has a first cylinder of a first diameter bordered by flanges which extend past the first cylinder. A base portion of the body is positioned at the second end. A bobbin extension portion is positioned between the coil support portion and the base portion. The bobbin extension portion includes a second cylinder of a second diameter which is smaller than the first diameter.

In the electric machine according to the present invention, conductor wires are housed inside slots so as to be arranged into multiple layers in one column so as to contact each other in a slot depth direction in each column such that a longitudinal direction of a long side of an oblong cross section of a conductor portion faces in the slot depth direction, and a thickness of a portion of an insulating coating that is formed on a surface of the conductor portion that faces in the slot depth direction is thinner than a thickness of a portion of the insulating coating that is formed on a surface of the conductor portion that faces in a direction of slot arrangement.

A drive device has a transmission housing with an external rotor-type electric motor. The electric motor is coupled to the transmission and is actuated by a motor electronic unit. The electric motor has a stator and a rotor which circulates about the stator and is connected to a drive shaft that is guided through a stator bushing with a first sleeve section for holding the stator bushing in the transmission housing in a rotationally fixed manner and with a second sleeve section. A groove frame insulation which surrounds the stator teeth in the axial direction is placed on the second sleeve section. An annular element which is arranged between the first sleeve section and the groove frame insulation and which has a joint element is placed on the second sleeve section of the stator bushing. The joint element engages into a joint contour of the first sleeve section.
