STATOR OF ELECTRIC MOTOR WITH OUTSIDE ROTOR FOR DRUM-TYPE WASHING MACHINE Russian patent published in 2008 - IPC D06F37/30 H02K3/34 

FIELD: household appliances.

SUBSTANCE: stator of electric motor with outside rotor for a drum-type washing machine contains a core ring of multilayer structure formed by steel plate folding. The stator has a ribbon-like base and the core ring teeth protruding from the base during spiralling of the steel plate starting from the lower layer to the upper layer as well as the upper and the lower insulators made of electric insulating material covering the upper and the lower sides of the spiral core ring and interadding its shape. Each upper and lower insulator contains three or more fixing details formed as the whole entity with the body and protruding from the inside of the core ring to the centre of the stator for stator fixation on the fixing side of the tub. The fixing detail has a fixing hole for fixation of the stator on the fixing side of the tub by the fixing detail. Each bulge of the upper and lower insulators contains the elevated part protruding from the side facing the other insulator in the opposite to the insulator direction for placing of insulators in full contact all together to improve insulator assembly.

EFFECT: improvement of technical and operation characteristics.
