摘要： The rotary machine comprises a rotary shaft (2) supported by first and second radial magnetic bearings (5, 6) that are electrically controlled by a control device (13), said rotary shaft being fitted with an axial abutment device (100) comprising a rotor formed by a disk (101) secured to the rotary shaft (2) and interposed between first and second stators (102, 104) formed annularly around the rotary shaft and each including at least one annular coil (103; 105) controlled electrically by a system for servo-controlling the axial position of the rotary shaft. The stator (104) of the axial abutment device (100) further comprises a secondary induction circuit (106), and the disk (101) secured to the rotary shaft comprises a primary induction circuit (107) so that during rotation of the shaft, electricity is excited in the secondary induction circuit in order to supply energy to the radial magnetic bearings.

摘要： A rotor for a fuel pump motor has a shaft and a rotor core fitted to the shaft. A commutator is located on the shaft adjacent one end of the rotor core. Windings wound around poles of the rotor core are connected to terminals of segments of the commutator. A cover is fitted to the other end of the rotor core covering the ends of the windings protruding from the core. The cover has axially extending legs which are pressed into gaps between adjacent heads of the rotor poles. The commutator has an integral shroud in the form of a radially outer peripheral skirt extending axially from a radial wall of the commutator base towards the rotor core to cover the terminals and the ends of the windings protruding from the commutator end of the rotor core. A gap is left between the rotor core and the skirt and there are holes in the cover and radial wall of the commutator for the passage of fuel to cool the rotor.

摘要： The invention concerns a magnetic guiding device (1) having at least one element (2) to be guided magnetically in the axial direction, e.g. a shaft or an actuation member that is movable in the axial direction, the element (2) having a radial flange (14) made of magnetizable material that is enclosed by an axial yoke (47) made of ferromagnetic material and constituting a stator, forming magnet gaps (51, 52) in which is producible, by means of a combination of permanent magnets and electromagnets (53, 54, 55), an axial magnetic flux with which the axial position of the element (2) can be influenced, which is characterized in that in the axial yoke (47), at least one pair of axially oppositely polarized permanent magnets (53, 54) are arranged axially next to one another, and an electromagnetic coil (55) is moreover arranged radially adjacently as an electromagnet, the magnetic flux in the coil (55) being controllable in such a way that an asymmetrical magnetic flux having an axial resultant force is producible in the magnet gaps (51, 52).
