ELECTRIC MOTOR AND ELECTRIC TOOL EQUIPPED WITH THIS MOTOR Russian patent published in 2010 - IPC H02K15/12 H02K3/44 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering, in particular to electric motors intended for use for instance in electric tools and comprising anchor (rotor) with winding installed in slots and coated by shaped polymer. In proposed electric motor for efficient compensation of heat produced by anchor (2a) with shaped polymer, in particular for efficient compensation of heat produced by winding (2e), for each of slots (2g) on external peripheral surface of filling layer (9a) of shaped polymer, which fills slot (2g) of core (21) with wound winding (2e), there are open grooves (2j) provided. Shape used for moulding of filling layer (9a) of shaped polymer consists of four elements, which may be separated along four directions of shift (in radial direction of core).

EFFECT: provides for efficient compensation of heat produced by such anchor with shaped polymer, in particular provision of efficient compensation of heat produced by winding in electric motor, comprising anchor with shaped polymer, and in electric tools comprising such electric motor.
