Abstract

See full text

An electric power tool includes a motor, a lifter, a firing pin, an electromagnet, a driving circuit, a latch, and a controller. The lifter is driven by the motor to drive the firing pin to perform a firing action. The driving circuit provides electric current to excite the electromagnet. The latch is moved by the electromagnet from a blocking position where the latch blocks the firing pin to move in a firing direction to a non-blocking position where the latch does not block the firing pin when the electromagnet is in an excited state. The controller, during an excitement period, controls the driving circuit to provide constant current for a first time period to excite the electromagnet to the excited state, and provide pulsating current for a second time period to keep the electromagnet in the excited state.
