摘要： A handheld grinder includes an elongated housing, an electric motor, an output shaft, a wall, a planar circuit board, and a motor drive circuit. The elongated housing defines a cavity therein and includes a motor case disposed at a front end and a handle portion to a rear end. The electric motor has a drive shaft that is mounted within the motor case. The output shaft is drivably coupled to the drive shaft of the electric motor. The wall separates the cavity between the motor case and the handle portion of the housing. The planar circuit board disposed in the handle portion of the housing. The motor drive circuit is accommodated entirely within the handle portion of the housing on the planar circuit board.

摘要： A fastening power tool such as a nailer is provided including a tool housing, an input unit actuated in response to an operator input, and a motor assembly including a motor housed within the tool housing. A control unit is provided including a controller programmable to control an operation of the motor and a decoder circuit configured to control a supply of power from a power source to the controller based on a status of the power source and a status of the input unit. The decoder circuit is configured to connect supply of power from the power source to the controller when the power tool is coupled to the power source prior to an engagement of the input unit, but disconnect the supply of power when the power tool is coupled to the power source after the engagement of the input unit.

摘要： A power tool is provided including a motor case and a handle portion. An electric motor having a drive shaft is mounted within the motor case. A circuit board is disposed in the handle portion to accommodate a motor drive circuit. The motor drive circuit includes a rectifier configured to receive an alternating current from an alternating current (AC) power source and convert it to a direct current supplied to a DC power bus, and a bridge circuit having motor switches connected between the rectifier and the electric motor. A bus capacitor is mounted on the circuit board and coupled across the DC power bus. An auxiliary capacitor having higher capacitance than the bus capacitor is switchably coupled across the DC power bus. The handle portion includes a support member protruding radially outwardly to accommodate the auxiliary capacitor.
