MOTOR STATOR ASSEMBLY AND METHOD FOR ITS MANUFACTURE (MODIFICATIONS) Russian patent published in 2006 - IPC H02K1/14 H02K1/08 H02K15/85 

FIELD: electrical engineering and specific features of the design of the motor stators and their manufacturing process.

SUBSTANCE: the motor stator assembly has a great number of yokes manufactured by superposition of a great number of steel plates having a preliminarily enclosed between the yokes and manufactured by molding of a magnetic material with the use of a mould, and a great number of frame bodies with a winding wound on them for generation of induced magnetism, and which are fitted on the outer parts of the poles, the mentioned poles contain: the guide section in the form of a round curve for accumulation of the magnetic flow, the neck section installed on which is the frame body connected to the rear surface of the guide section, and the connecting section formed on the rear surface of the neck section and joined to the yoke. The frame body has an inner wing attached to the outer part of the pole guide section, body connected to the inner wing and installed on the pole neck section for winding of the winding, and an outer wing projecting from each side of the body and covering the winding. Three modifications of the method for manufacture of the given stator of the electric motor are offered, they characterize both different features of manufacture of separate parts of the stator, in particular, with the use of the methods of the powder metallurgy, and the sequence of their assembly.

EFFECT: reduced expenditures connected with manufacture of the motor stator, and improved serviceability of the latter.
