FIELD: electricity.
SUBSTANCE: invention relates to manual power tools. Electric hand tool includes an electric motor, device for determination of rotation rate for the electric motor, braking device to brake the electric motor and an actuator to brake the electric motor. The actuator is designed to actuate the braking device when rotation rate defined by the device for determination of rotation rate for the electric motor is equal or less to the preset value, which is set upon issue of instruction to cut off electric current from the electric motor.
EFFECT: improved comfort of use at operation of the hand tool due to optimisation of braking operation for the electric motor.
