Abstract
A pump motor having a permanent magnet rotor, a containment shell, a wound stator, a motor housing, a pump head, a shaft, which is secured in the containment shell on the one hand and in the pump head on the other hand, and a fixed bearing, which is pressed or injected into the permanent magnet rotor and rotatably mounts it on the shaft. The pump motor provides a reliable and economically producible bearing of the permanent magnet rotor on the shaft in a generic pump motor, in which the bearing abutting uniformly against the shaft over the entire bearing length and during a complete rotation can be achieved, small angle errors can be compensated, and noises can be reduced.
