An electric tool includes a motor, an operation part provided to be operable by a user, a motor drive control unit configured to perform control of driving the motor in response to the operation part being operated, a temperature sensor, and a temperature determination unit configured to determine overheating of the motor. The temperature determination unit is configured to estimate a temperature of the motor based on a drive situation of the motor and a detection result of the temperature sensor, and to determine the overheating of the motor based on the estimated temperature.

Electric tool

An air compressor includes a tank unit, a compressed air generating unit, a motor unit, a driving current generating unit, a control unit and a temperature detecting unit. The tank unit stores a compressed air. The compressed air generating unit generates the compressed air to be stored in the tank unit. The motor unit drives the compressed air generating unit. The driving current generating unit generates a driving current of the motor unit. The control unit drives the motor unit by controlling the driving current generating unit. The temperature detecting unit detects a temperature of the driving current generating unit. The control unit changes the driving current of the motor unit by controlling the driving current generating unit based on the temperature detected by the temperature detecting unit.
