とするクラツチ式電動回転工具の制御装置。 A motor includes a cylindrical casing closed at one end, an output shaft pivotally supported by the casing and extending outward, a drive shaft mounted within the casing, and the drive shaft and the output shaft The planetary gear mechanism includes an internal gear rotatably provided within the casing and a plurality of planetary gears meshing with the internal gear, and the planetary gear mechanism A through hole is provided in the closed end of the casing, which is supported by the disk support of the output shaft and meshes with the pinion gear of the drive shaft, and which faces the outer surface of the closed end of the internal gear, and the through hole serves as a fixed stage for the clutch. A flanged sleeve is brought into contact with the outside of the closed end of the casing, this sleeve is surrounded by a sleeve cover, and a cap is screwed onto the sleeve cover so as to be movable forward and backward. A coil spring is installed to elastically press the flanged sleeve to elastically engage the steel ball with the internal gear, and an auxiliary switch is installed on the flange portion of the flanged sleeve so as to respond to the displacement of the clutch operation. The operation of this auxiliary switch energizes the switching circuit to cut off the power to the electric motor, and at the same time, the switching circuit is self-maintained and the armature of the electric motor is short-circuited by the switching circuit to stop the electric motor from running. A control device for a clutch-type electric rotary tool, characterized in that it is provided with a control circuit for dynamic braking.
