摘要： An electric machine that allows a reduction in number of winding portions and a reduction in amount of permanent magnets used is provided. An electric machine includes a magnetic pole piece array including a plurality of magnetic pole pieces spaced along a permanent magnet array. The permanent magnet array is in immovable relation with winding portions. The pitch of a plurality of permanent magnets and the pitch of a plurality of magnetic pole pieces are determined such that magnetic flux flows through two of the permanent magnets magnetized in the same direction and located in the permanent magnet array with one permanent magnet interposed between the two permanent magnets, and also flows through one or two of the magnetic pole pieces facing the one permanent magnet interposed between the two permanent magnets and magnetized in a direction of magnetization different from the direction of magnetization of the two permanent magnets.

摘要： An electromagnetic actuator (100) comprises magnets (109, 111, 113, 115, 11), and a ferromagnetic structure (103) accommodating control conductors (118, 121, 123, 125). The magnets and the structure can move with respect to one another under control of control currents in the control conductors. The magnetic field in a gap (107) between the magnets and the ferromagnetic structure is oriented perpendicular to the direction of relative movement. The structure (103) accommodates damping conductors (127) that form closed loops of an electrically conductive material, different from the ferromagnetic material. The damping conductors (127) provide a damping force induced by the relative movement.

摘要： The invention relates to a claw-pole machine comprising a stator, a rotor and an excitation coil wound around a solid core in the rotor. The solid core extends in the radial direction in the form of two claw magnet wheels which alternately terminate in pole fingers extending axially from two sides. U-shaped metal sheets are placed on the solid parts of the claw pole fingers facing outwards radially. Said metal sheets are stratified on top of each other in the axial direction in order to prevent eddy currents.

摘要： The dynamics of a magnetic gear mechanism are intended to be improved. For this purpose, a magnetic gear mechanism with a stator, a first rotor, which has permanently excited magnet poles (2, 3), and a second rotor, which likewise has permanently excited magnet poles, is proposed. The rotors are magnetically coupled to the stator. In each case one coil (5) is wound around each of the magnet poles (2, 3) of the first rotor. The coils (5) of the magnet poles (2, 3) are connected in series. The series circuit of the coils (5) can be supplied direct current in order to alter the magnetic flux through the magnet poles (2, 3) in comparison with the de-energized state.

The stator (3) has an armature coil (302) configured to form a magnetic circuit for driving. The magnetizing coil (504) is configured to form a magnetic circuit for magnetizing. The rotor (2) has a constant magnetized magnet (2031), a rotor core (203) and a variable magnetized magnet (2022). The rotor core (203) holds the constant magnetized magnet (2031). The constant magnetized magnet (2031) is arranged closer to the magnetic circuit for driving than the variable magnetized magnet (2022). The variable magnetized magnet (2022) is arranged closer to the magnetic circuit for magnetizing than the constant magnetized magnet (2031).
