Appliance having an a.c. series motor and having switching means for switching this motor to different speeds

摘要

In an appliance having an a.c. series motor, which comprises a rotor coil configuration and two stator coils, switching means are provided for switching the a.c. series motor to different speeds or speed characteristics. Both coil ends of each of the two stator coils are accessible from outside of the a.c. series motor and are connected to the switching means. The switching means connects either one stator coil or both stator coils in series or both stator coils in parallel and in series with the rotor coil configuration.
