ELECTRIC MOTOR, IN PARTICULAR FOR FANS FOR COMBUSTION AIR OR FOR MIXTURE OF AIR AND GASEOUS COMBUSTION PRODUCT, IN GAS BURNERS, STATOR ASSEMBLY FOR SUCH ELECTRIC MOTOR AND ASSEMBLY METHOD FOR SUCH A STATOR ASSEMBLY Russian patent published in 2020 - IPC H02K1/14 H02K5/04 H02K5/16 H02K3/52 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Electric motor (10) comprises stator assembly (11) comprising multilayer stack (12) provided with perimeter frame (13) with at least one pair of pole pieces (14, 15), each of which consists of main part (16, 17) of winding and expanded head (18, 19), frame (20) for supporting multilayer stack (12), coil of current-conducting wire (21, 22) for each pole tip (14, 15), with insert of insulating support (23, 24); means for reducing friction of rotation, for drive shaft (26) of rotor (25), and rotor (25), with drive shaft (26). Perimetric frame (13) and pole tips (14, 15) are mutually separate elements connected by means of fastener (29). Each insulating support (23, 24) consists of ring-shaped main part (30, 31) with through axial hole (32, 33), which has contour, to surround corresponding main part (16, 17) of winding. Bearing frame (20) is interlocked by mutual interlocking between perimeter frame (13) of pack (12) and insulating supports (23, 24).

EFFECT: technical result is improved manufacturability of structure.
