摘要： A protective cover for a generator in a running state includes a main body, a frame, and a top cover. The main body includes side wings capable of being rolled up and unfolded down. The side wings are enclosed to define an accommodating cavity. The accommodating cavity defines an upper opening and a lower opening and is matched with the generator. The frame is arranged in the accommodating cavity and is fixedly connected with the generator. The frame is fixed with the side wings. The top cover is openable and arranged on a top portion of the main body and covers the upper opening on an upper end of the accommodating cavity. When the generator is in the running state, the protective cover is used through the frame. Especially in a humid environment, the protective cover protects the generator from short circuit and protects an operator from electric shock.

摘要： Selectable current limiting for a power tool. One embodiment provides a method for selectable current limiting for a power tool including determining, using a current sensor, an average current and determining whether the average current exceeds a predetermined current threshold. The method also includes determining a deviation of the average current from the predetermined current threshold and reducing a PWM duty ratio proportional to the deviation of the average current from the predetermined current threshold. The PWM duty ratio corresponds to a PWM signal provided to an inverter bridge.

摘要： The present disclosure describes a drive circuit for an actuator of an actuator device. The drive circuit includes an interference suppression branch for reducing interferences. The interference suppression branch includes two conductor branches extending along a longitudinal axis and each comprising at least one conductor body. The two conductor branches extend through at least two imaginary conductor alignment sections of the interference suppression branch that are lined up in a row in an axial direction of the longitudinal axis. The two conductor branches have a first portion arranged inside a first conductor alignment section that run obliquely towards one another.
