摘要: A motor suited for use in a direct drive laundry machine. The described motor has a stator core including an annular ring with an inner diameter between 120 mm and 250 mm, a radial width between 5 mm and 15 mm, and 24 or 27 stator poles projecting outward from the annular ring a distance of between 15 mm and 40 mm. Each stator pole is associated with one of three phase windings. A rotor for the motor has inwardly facing permanent magnet poles whereby the ratio of rotor poles to stator poles is 4:3.

摘要: A BLDC motor for driving a cross flow fan in an air-conditioning application has an external rotor and an internal stator. The stator is a salient pole stator with insulated pole teeth and conductor coils. The inner diameter of the stator supports a single bearing. An electronic PCBA for control of the BLDC motor is optionally attached to the stator, all of which is encapsulated in a thermoset resin. The rotor comprises permanent magnet component(s) and a rotor frame. The rotor frame includes a stub axle that engages with the bearing element and features to provide torsional or rotational compliance between the rotor magnets and the fan. A level of compliance is provided between the bearing element and the stator to allow for angular misalignment between the rotational axis of the fan and the stator.
