Abstract
An electric work machine in one aspect of the present disclosure includes an output shaft, a brushless DC motor, a first positive-side conduction path, a first negative-side conduction path, a first switch device, a manual switch, a rotation sensor, and a controller. The first switch device is on the first positive-side conduction path or the first negative-side conduction path. The controller controls a magnitude of a conduction angle based on an actual rotational frequency and a target rotational frequency of the brushless DC motor.
