ELECTRIC TOOL Russian patent published in 2014 - IPC B25F5/00 B23B45/16 B25D16/00 B25B21/00 B25B23/147 

FIELD: electricity.

SUBSTANCE: invention relates to the manual power tool. The tool consists of a body, electric motor located in the body, clutch, noncontact torque sensor, clutch control system and mechanical torque limiter. The clutch is intended for torque transmission and breaking the torque transmission between the electric motor and working body of the tool. The noncontact torque sensor is intended for determination of the torque effecting the working body of the tool during operation. The clutch control system is intended for controlling the coupling and decoupling of the clutch according to the torque value, determined by the noncontact torque sensor. The mechanical torque limiter is intended for preventing of overload on the working body of the tool and is located on the paths of the torque transmission between the electric motor and working body of the tool.

EFFECT: protection from overload of the tool structure elements performing torque transmission is ensured.
