| description | PROBLEM TO BE SOLVED: To provide a power tool capable of controlling load current conforming to actual temperature of an electric motor, and having excellent assembling workability since conventionally there are provided constitutions reducing load current according to supplied load current and reducing load current according to temperature of the motor detected by a temperature sensor imbedded in a stator in order to prevent burnout caused by overheat of the built-in electric motor and there are such problems as not always to control load current conforming to temperature of the electric motor in the former constitution and to become worse in assembling workability in the latter constitution in the power tool. SOLUTION: This power tool 1 is provided with a baffle plate 8 for controlling an air flowing passage for motor cooling air on the leeward side of a rotor 4, mounts a sensor 10 for detecting temperature of the motor cooling air on the baffle plate 8, and controls load current of the electric motor 3 according to the temperature of motor cooling air detected by the sensor 10. |
