Abstract:
A power tool includes a brushless motor, a supplying circuit, and a controller. The brushless motor is configured to drive and rotate when a voltage applied to the brushless motor is larger than or equal to an induced voltage. The supplying circuit is configured to apply a driving voltage to the brushless motor. The controller is configured to control the supplying circuit. The supplying circuit includes a rectifying circuit, a capacitor, and a switching circuit. The rectifying circuit is configured to rectify an alternating voltage and output a rectified voltage. The capacitor is configured to smooth the voltage inputted via the rectifying circuit. The switching circuit is configured to perform a switching operation based on a PWM signal to adjust a period during which the driving voltage is applied. The controller is configured to set a duty ratio within a prescribed range, and output the PWM signal of the set duty ratio to the switching circuit to control the switching operation. The controller is configured to perform a constant-number-of-rotation control for controlling the brushless motor to rotate at a target rotation number by changing the duty ratio. The capacitor has a capacitance allowing a smoothed voltage to be always larger than or equal to the induced voltage during the constant-number-of-rotation control.

Claim (Index 6):
The power tool according to  claim 5 , further comprising:\n a circuit board to which the switching circuit is mounted; and a board case accommodating the circuit board, wherein the capacitor is positioned at an end of the board case at a side where the opening portion is formed.
