A driving tool comprising: a plunger; a motor configured to move the plunger from a bottom dead center to a top dead center; a driving unit configured to use the plunger to drive a fastener by moving the plunger from the top dead center to the bottom dead center; a voltage fluctuation information acquisition unit configured to acquire voltage fluctuation information indicating a fluctuation amount of a voltage applied to the motor during movement of the plunger; and a control unit configured to control the motor based on the voltage fluctuation information.

Driving tool

A striking tool includes: a motor including a rotor; a plunger configured to be movable from a bottom dead point to a top dead point by the motor; a moving unit configured to move the plunger from the top dead point toward the bottom dead point; a speed variation acquiring unit configured to acquire an amount of variation in rotating speed of the rotor; and a control unit configured to control the motor, based on the amount of variation acquired by the speed variation acquiring unit.

Striking tool

An air compressor includes a motor, a compression mechanism configured to be driven by the motor to generate compressed air, a tank configured to store the compressed air, a controller configured to control driving of the motor, an air extraction port configured to extract compressed air from the tank, and an extraction pressure sensor configured to measure an extraction pressure that is a pressure of compressed air extracted from the air extraction port. The controller is configured to control the driving of the motor by referring to the extraction pressure.
