摘要:
A permanent magnet motor having an axially magnetized pull magnet consisting of a baseplate on which a stator lamination stack having stator windings is disposed, wherein a hub is disposed opposite the baseplate, the hub being connected to a shaft that is supported with respect to a bearing bush via one or more fluid bearings wherein the hub carries at least one annular rotor magnet that lies radially opposite the stator lamination stack, wherein a pulling device acting in an axial direction and operating under the influence of magnetic tensile forces is disposed in the region between the hub and the stationary part of the motor, wherein the pulling device consists of a permanent magnetic pull magnet on the side of the rotor that interacts magnetically with surfaces on the side of the stator.
