BRUSHLESS WIPER ENGINE Russian patent published in 2017 - IPC B60S1/08 H02K7/116 H02K9/22 

FIELD: engines and pumps.

SUBSTANCE: fixed part, rotary part rotatable mounted in the fixed part, gear that transmits the rotation of the rotary part to the wiper element, and a reducer housing in which the gear is located are fixed in the motor casing. The motor housing in which the fixed part 35 and the gear housing 41 in which the gear SD is mounted are made of aluminium and most of the heat that is generated in the stationary part 35 during the operation of the brushless wiper engine 20 can be dissipated directly to the outside of engine casing 31.

EFFECT: efficient dissipation of heat transmitted to the motor housing outwards can be achieved, size and weight can be reduced, electromagnetic interference can be suppressed and resistance to heat can be increased, which does not require costly components capable of withstanding high temperatures, and manufacturing costs can be reduced.
