摘要： A control device including a first shell; a battery pack mounting part; a first control unit, which is provided in the first shell and is used for cutting off power transmission from a battery pack to an electric power tool when the battery pack is abnormal; a first user operation unit, which is arranged on the first shell and is operated by a user to control the electric power tool; and a first interface, electrically connected to the first user operation unit. An electric power tool system comprises the control device and the electric power tool. The control device can be adapted to different types of electric power tools, and the control device is not provided with a control portion used for adjusting working parameter of the electric power tool, such that the control device can more flexibly match an upgraded new electric power tool.

摘要： A power tool includes a brushless motor, including a stator and a rotor; an inverter circuit, including a plurality of switch components, where the plurality of switch components are configured to perform a switch action to control driving of the brushless motor; and a controller, electrically connected to the inverter circuit and the brushless motor, the controller including a load detection module configured to detect a parameter indicating a workload of the brushless motor. In response to the parameter being less than a set threshold, the controller is configured to control the brushless motor to maintain a first target rotational speed; and in response to the parameter being greater than or equal to a set threshold, the controller controls the brushless motor to maintain a second target rotational speed. The first target rotational speed may be greater than the second target rotational speed.
