摘要： A driving apparatus for a washing machine includes a single-phase outer rotor brushless motor and a driving wheel. The motor drives the driving wheel and includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The rotor includes a rotor yoke, and a permanent magnet. An inner surface of the permanent magnet and an outer surface of a tooth tip are opposed to each other and define an uneven gap there between for allowing the rotor to rotate relative to the stator. A radial width of the gap associated with each magnetic pole progressively increases from a center portion toward circumferential ends of the magnetic pole, and a radial width of the gap associated with each magnetic pole is symmetrical with respect to a center axis of the magnetic pole along the circumferential direction.

摘要： An actuator for a vehicle door lock mechanism has a motor, a first gear, a second gear and a third gear. The motor has a shaft to which the first gear is connected. The motor rotates the first gear, which in turn drives the second gear and the third gear. A non-tooth part is formed on the second gear. A projection is formed on the third gear. Stops are arranged for stopping rotation of the third gear. When the second gear rotates to a position where the non-tooth part corresponds to the third gear, the projection is spaced from one stop by an angle. When the second gear rotates further, the gears re-mesh and the third gear rotates till the projection contacts the stop.

摘要： A driving device includes a motor and a gearbox. The gearbox includes a sun gear, planetary gears surrounding and meshing with the sun gear, and an internal ring gear surrounding and meshing with the planetary gears. The motor is a single phase motor. The sun gear is integrally formed with a rotary shaft of the motor. A power tool is also disclosed which includes the driving device, a rotatable working head driven by the driving device, and a striking unit disposed between the driving device and the working head. By integrating the sun gear and the motor rotary shaft to form an integral gear shaft, the number of the teeth of the sun gear can be reduced to five or less. Therefore, the transmission ratio of the gearbox can be effectively increased without changing the maximum geometric outer diameter.

摘要： A driving device includes a motor and a gearbox. The gearbox includes a first sun gear, first planetary gears surrounding and engaged with the first sun gear, and a first internal gear ring surrounding and engaged with the first planetary gears. The first sun gear is coaxially fixed to a rotary shaft of the motor. Meshing planes of the first sun gear and the first planetary gears are slanted with respect to the rotary shaft. Each of the first planetary gears is subjected to an externally-exerted first force and exerts a transverse component of force toward the rotary shaft on the first sun gear. The motor structure of the driving device is simplified, which makes the driving device have a more compact structure, lighter weight and lower cost.
