摘要: A stator assembly for a BLDC motor includes a stator core, at least one magnet wire wound on poles of the stator core, an end insulator mounted on an end surface of the stator core, a non-conductive mount member mounted on the outer circumferential surface of the stator core, and conductive terminals mounted on the non-conductive mount member. Each conductive terminal includes: a main portion mounted on the non-conductive mount, a tang portion extending from a first longitudinal end adjacent the end insulator and folded over the main portion, and a connection tab extending angularly from a second longitudinal end. A contact portion of the magnet wire is wrapped around the tang portion and fused to make an electric connection to the conductive terminal.

摘要: A vehicle includes a battery, an electric machine, a thermistor, and a controller. The electric machine is configured to draw electrical power from the battery to propel the vehicle. The electric machine has a rotor and a stator. The stator has a core, interconnected hairpins, and a neutral bar. The core defines slots. The interconnected hairpin windings are arranged within the slots and are arranged to form a plurality of electrical phases. The neutral bar is connected to each of the electrical phases and defines an orifice. The thermistor is disposed within the orifice and is configured to sense a temperature of the electric machine. The controller is programmed to control a power output of the electric machine based on the temperature of the electric machine.

摘要: A stator includes insulation including a back insulation portion covering a back stator portion, a first tooth portion covering a first tooth, a second tooth portion covering a second tooth. A first flange portion has a first face that is in facing relationship with the back insulation portion. A second flange portion has a second face that is in facing relationship with the back insulation portion. The first face and the second face together substantially defining a boundary plane, such that a cross-sectional slot area is defined between the back insulation portion, the first tooth portion, the second tooth portion, and the boundary plane. A plurality of conductive wires are arranged in the cross-sectional slot area, the wires defining a cross-sectional winding area within the cross-sectional slot area. A ratio of the cross-sectional winding area to the cross-sectional slot area is greater than or equal to 0.45.

摘要: An axial gap motor having a rotor and a stator core. A plurality of pressed powder teeth extends in a radial direction of the stator core and each has a trapezoidal shape in which a circumferential length of a pressed-powder-tooth-radial-direction-outer-end portion is larger than a circumferential length of a pressed-powder-tooth-radial-direction-inner-end portion. The rotor includes a plurality of field magnets, each configured such that a circumferential length of a magnet-radial-direction-inner-end portion is greater than or equal to a circumferential length of a magnet-radial-direction-outer-end portion. When the rotor and the stator core rotate relative to each other about a rotation axis, a part of the field magnets first overlaps with pressed-powder-tooth-radial-direction-inner portions of pressed powder teeth, and while the field magnets are located at a q-axis position with respect to the pressed powder teeth, adjacent ones of the field magnets individually overlap with one pressed powder tooth.

摘要: The slot liner (13) includes a laminated insulation sheet (131) having a length (L1) longer than a length (L2) of a stator core in an axial direction and a pair of reinforcing sheets (135, 136). The laminated insulation sheet includes an outer insulation sheet (134) in contact with an inner surface (112d) of the slot and an inner insulation sheet (132) in contact with a conductor. Each of reinforcing sheets is folded back in the axial direction in such a way as to cover an end surface (134a, 134b) of the outer insulation sheet and includes a folded portion (135e, 136e) that covers the end surface of the outer insulation sheet, a first end portion (135f1, 136f1) disposed between the inner surface of the slot and the outer insulation sheet, and a second end portion (135g, 136g) disposed between the outer and inner insulation sheets.

摘要: Provided are an insulation shielding member which may insulate a coil and a stator core from each other, and simultaneously, shield an electric field caused by the coil, and a motor using the same. The insulation shielding member of the present disclosure may perform not only an insulation function but also a shielding function simultaneously, and shield the electric field caused by the coil to prevent corrosion from occurring in a bearing, thereby reducing the vibration and noise of the motor.
