ELECTRIC MOTOR Russian patent published in 2009 - IPC H02K11/00 

FIELD: electricity.

SUBSTANCE: present invention relates to electrical engineering and can be used in electric motors, used in home appliances, such as laundry and dish-washing machines. The electic motor (1) contains a stator (2), winding (3), with more than one restrictor (4), which allows for fitting into the stator (2) and a restricting winding. The thermoswitch (6) switches off electrical current when there is overheating at a defined temperature. It contains an adapter (7), providing for connecting the thermoswitch (6) in series with winding (3). The adapter is fitted on the electric motor (1) with possibility of attaching/removing, has two contacts (8) for connecting to a power supply. The contacts of the winding (18) are joined to the initial and terminal ends of winding (3). Holders (9) support the thermoswitch (6) and provide for contact of the thermoswitch (6) on a certain area of the surface and conduct electric current from the contacts of the winding (18) and winding (3). The mounting seat (10) of the thermoswitch (6) is situated between holders (9), providing for its mounting with possibility of removal. Thermoswitch (6) stops operation of the electric motor (1) by switching off electric current to the electric motor (1), when the electric motor (1) overheats due to overloading, resulting from presence of foreign objects in water, or due to blocking of the rotor, giving rise to fire hazards.

EFFECT: increased security due to easier connection and disconnection of the thermoswitch.
