Description

technical field [0001] The invention relates to an electric tool, in particular to an electric tool with an electronic module. Background technique [0002] The tool industry offers a wide variety of hand-operated power tools to perform operations on various workpieces. Such power tools include, for example, circular saws, jigsaws, routers, drills, and the like. These power tools generally include a frame and a drive motor mounted in the frame. The driving motor is configured to drive the working parts (such as the saw blade in the circular saw, the planer in the router, etc.) to process the workpiece (such as a piece of wood, etc.). [0003] In order to control the operation of the driving motor and provide protection for electric tools, many electric tools have electronic modules integrated inside them, which can provide various functions, such as speed control, overload protection, charge and discharge protection, thermal protection and so on. The cost of an electronic...
