ABSTRACT:
An apparatus for changing the rotational speed of a mechanism includes an input shaft, several planetary gear units, an output rotor, a rotating disc and a casing. The planetary gear units are connected together. The sun gear of the first unit is connected to the input shaft and the carrier of the last unit is connected to output rotor. An internal gear of one of planetary gear units can rotate in the casing but can be stopped by an internal gear stopping device. The input shaft is connected to the rotating disc. The rotating disc can be brought into contact with the output rotor by a disc-contacting device. The disc-contacting device and the internal gear stopping device are driven in a complementary manner. When the internal gear stopping device is excited and the disc-contacting device is unexcited, the output rotor rotates at a low speed level. When the disc-contacting device is excited and the internal gear stopping device is unexcited, the output rotor rotates at a high speed level. This apparatus can be used as a driving device for a drum type electric washing machine.
