摘要： In order to provide a tool in which a motor is assuredly prevented from being restarted when power is turned on again after a power supply interruption due to a contingency, a disk grinder 1 includes a motor 2 and a switch 12 switchable between an ON position at which the motor is driven by an operator and an OFF position at which the motor is stopped. Furthermore, first and second restart prevention means 60, 90 are provided to disable driving of the motor until the switch is turned again to the ON position when power supplied to the motor 2 falls below or under a predetermined value.

摘要： In order to provide an electric tool such that the capacitances of noise-suppressing film capacitors can be increased without increasing the diameter of a handle section, the housing of the electric tool comprises: a body section that stores a brushless motor, a striking mechanism part, and a portion of an output part; a handle section, whose one end is connected to the body section; and a storage section that is formed on the other end of the handle section. A pair of film capacitors for removing noise generated from an inverter circuit are mounted on a capacitor substrate and stored side by side inside the handle section. The film capacitors are connected in parallel with each other, thereby providing a capacitor having a larger total capacitance than before.

摘要： A power tool includes: a brushless motor; a rectifier circuit; a smoothing circuit; an inverter; a controller; an operating part; and a switch. The switch is rendered ON in accordance with an operation performed in the operating part by a user to allow power to be supplied to the inverter circuit by the rectifier circuit through the smoothing circuit and rendered OFF in accordance with release of the operation by the user to interrupt the inverter circuit from the rectifier circuit to halt supplying the power to the inverter circuit. The smoothing circuit includes a first capacitor and a second capacitor connected in parallel. The controller is configured to control the switching operations of the inverter circuit to drive the brushless motor in accordance with a signal inputted in accordance with the operation performed in the operating part by the user.
