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： An electromagnetic suspension system uses a linear motor having coils disposed around the outer periphery of a stator and permanent magnets disposed along the inner periphery of a mover. Wiring is routed through a gap between a first rod and a second rod. Thus, contact between the wiring and the second rod is avoided, and the wiring is protected. Consequently, it is possible to ensure reliability for the electric system of the electromagnetic suspension system.

摘要： A stator includes an annular stator core having a plurality of slots arranged in the circumferential direction at predetermined intervals and a stator coil formed of a plurality of electric conductor wires mounted on the stator core. Each of the electric conductor wires has a plurality of in-slot portions received in the slots of the stator core and a plurality of turn portions that connect, on the outside of the slots, adjacent pairs of the in-slot portions. The stator coil has first and second coil end parts and that respectively protrude axially outward from a pair of axial end faces of the stator core. At each of the coil end parts, the turn portions of the electric conductor wires are stacked in a radial direction of the stator core, and the axial heights h1 of the turn portions are set so as to gradually increase from the radially inside to the radially outside.
