Abstract: An electric motor having low vibration and/or noise comprises a rotor or stator comprising permanent magnets each comprising at least two pole pairs, with an internal flux gap within the permanent magnets between adjacent internal pole pairs. The internal flux gap between the internal pole pairs may be similar to an external pole to pole physical spacing between adjacent poles of adjacent magnets. The motor is suitable for use in for example a laundry washing machine or dryer or washer-dryer.

Abstract: An electric motor assembly suitable for use in a laundry washing machine or dryer or washer-dryer, is of the axial flux permanent magnet synchronous motor direct-drive type, with the stator coils carried by a rotor bearing housing component to provide a primary heat conduction pathway from the stator coils to the bearing housing 5 component, and to a drum of the machine. The motor may be positioned between axially spaced bearings mounting the rotor.

Abstract: A laundry appliance is provided, comprising a motor and a controller connected to the motor. The controller determines at least one characteristic of the motor, identifies the motor from a plurality of possible known motors based on the at least one characteristic, identifies the rotor from a plurality of possible known rotors based on the at least one characteristic, and configures at least one motor operation parameter based on the identity of the motor and/or rotor. The at least one characteristic may include the resistance of a stator coil and/or a magnetic flux constant.
