ELECTRIC TOOL Russian patent published in 2016 - IPC B25F5/00 H02P6/14 H02P6/18 H02K7/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and may be used for control of the working tool connected with engine. Proposed electric tool comprises a brushless motor with several stator windings, made with option for its rotor to rotate in accordance with the voltage supplied to the stator windings formed in accordance with the rotor rotation; rectifier circuit to rectify AC voltage; a smoothing capacitor for smoothing the AC voltage rectified by the rectification circuit to obtain a pulsating voltage, maximum value of which exceeds the induced voltage, and the minimum value is less than the induced voltage; inverter circuit configured to perform switching operations for alternate switching of output pulse voltage to the stator windings.

EFFECT: technical result is increased power rate.
