Abstract

The invention discloses control equipment of an electric tool, and an electric tool system. The control equipment of the electric tool comprises a shell and a control module contained in the shell, the control module is used for being electrically connected with the brushless motor of the electric tool and controlling working parameters of the brushless motor, and the control equipment of the electric tool is further provided with a cooling system used for reducing the temperature of the control module. The cooling problem of electronic components in the control equipment of the electric toolis effectively solved, the appearance structure is small, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric tool control device and an electric tool system. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] As far as the electric tool is concerned, it is generally equipped with a motor for providing a power source. Wherein, the motor can be a brushed motor or a brushless motor. Among them, the brushless motor has the characteristics of long service life, simple structure, safety and high efficiency, so it has a broad application prospect in high-power electric tool systems. For brushless motors, electronic control equipment needs to be configured to control the working parameters of the brushless motors. The control device is generally integrated with the brushless motor. [0004] The electronic control equipment is equipped with some high-p...
