Abstract
A pump has a DC pump drive motor with an electrically driven stator winding and a rotor which is mounted such that it can be driven in rotation in the field of the stator winding. The motor also has a motor shaft, a permanent-magnet ring and a holder which is mounted on the motor shaft and on which the permanent-magnet ring is held. The pump has a rotation-prevention device configured to secure the permanent-magnet ring against rotation about the axis of the rotor on the holder. A domestic appliance, in particular a dishwasher or a washing machine, is provided with a pump of this kind.
