The insulator has an outer wall surrounding a central axis and erected to upwardly extend from the end surface, a plurality of teeth cover portions radially inwardly extending from the outer wall, and a plurality of inner walls erected at an end portions of the teeth cover portions. The coil windings are placed between the outer wall and corresponding inner walls. A passage portion radially extends and is formed in at least one of the teeth cover portions to pass the yarn, and the passage portion is spaced from the coil windings.

摘要： The present disclosure generally relates to a rotary electric machine having a stator winding in which bobbins forming a coil are arranged in a circumferential direction. The bobbin includes plate-like flanges on an inner and outer circumferential side. Each flange has edges corresponding to a circumferential and an axial direction. One or more plate-like members form two or more groove portions in a radial direction in parallel with the flanges between the flanges provided on the inner and outer circumferential sides. The coil includes an electric wire wound around the groove portion between the flange and the plate-like member and the groove portion between adjacent plate-like members. As such, the electric wires can be wound in an aligned manner between the plate-like members. Also, slot space factor is improved, coil end is reduced, and output and efficiency of the rotary electric machine is improved.

摘要： An electrical machine, in particular an electric motor of a motor vehicle, having a stator and having a rotor which has a rotation axis. An electrical machine can be a brushless electric motor (DC motor) or a synchronous machine, but also a generator. The stator or the rotor has an electromagnet structure, and the other has a permanent-magnet structure which comprises a first quantity of permanent magnets and a second quantity of permanent magnets. At at least the operating temperature (T), the magnetic coercive field strength (Hcji) of the first quantity is greater than the magnetic coercive field strength (Hcj2) of the second quantity. Further, two methods for producing hybrid magnets are provided.

摘要： A generator rotor system having various features is disclosed. The generator rotor system has at least one main stage generator rotor with winding-pole sets spaced annularly about the rotor. The tendency of the windings to distort and or displace under the centrifugal force of the spinning rotor is ameliorated by a winding retention member disposed axially outboard of the winding-pole sets. The winding retention member may also have a one or more cooling oil routing hole to enhance the flow of cooling oil among the windings.

摘要： The present invention provides an axial air-gap rotary electric machine that is provided with: a stator in which a plurality of core members, which have an iron core, a coil that is wound around the outer periphery of the iron core, and a bobbin that is disposed between the iron core and the coil, are arranged in a circular shape centred around a rotational axis; and at least one rotor that faces an end surface of the iron core with a prescribed air gap therebetween in the radial direction of the rotational axis. Therein, the bobbin has a cylinder portion into which the iron core is inserted, and a flange portion that extends for a prescribed length around the outer periphery of the cylinder portion and in a vertical direction, and the coil is wound around the outer periphery of the cylinder portion by regular winding, and is formed by a sequence of layers wherein the number of turns for each layer wound further to the outside than the layer that is wound so as to be in contact with the flange portion is at least one less than the number of turns in the adjoining inner layer.

摘要： A chip-scale vibrational energy harvester circuit may include magnets and coils with magnetic cores provided in proximity thereto. Either the magnets or the coils may be mounted on a micro-electromechanical spring system (MEMS) that is coupled to a stationary frame. The counterpart component may be mounted on the stationary frame. When the stationary frame experiences vibrational activity, the magnets and the coils may move with respect to each other, causing variations in the flux passing through the coils. The variations in the flux may induce voltages across the coils. The induced voltages may be rectified and stored as energy for later use.

摘要： In a mechanically and electrically integrated driving apparatus, a common coolant flow channel for cooling a motor unit and an inverter unit is disposed inside a wall portion of a frame unit. Power modules are placed in close contact with an inner wall surface of the frame unit. A bracket that is separate from the frame unit is fitted into the frame unit. A space inside the frame unit is divided by the bracket into: a space in which the motor unit is housed; and a space in which the inverter unit is housed.
