摘要： A pole shoe element for an electrical machine is described. The electrical machine has a stator, a rotor and an air gap between the stator and the rotor. The pole shoe element contains a magnet receiving section which extends in a longitudinal direction of the pole shoe element, in which the pole shoe element in a peripheral direction of the rotor has a first width in a first radial inner position and in the peripheral direction has a second width in a second radial outer position. The second width is smaller than the first width.

摘要： A pole shoe arrangement for a rotor or a stator of an electrical machine having an air gap between the stator and the rotor is disclosed. The pole shoe arrangement has a pole shoe element having an inner end and an outer end opposing the inner end. The inner end lies opposite the air gap when the pole shoe element is in an assembled state. The pole shoe element has a receiving surface for receiving a permanent magnet between the inner end and the outer end. The pole shoe arrangement has a guiding facility to guide the permanent magnet in a radial direction from the outer end to the inner end and to limit a movement of the permanent magnet at right angles to the radial direction.
