Abstract

The invention relates to an electric tool, which comprises a shell, a motor, a plurality of Hall sensors, a first circuit board and a second circuit board, wherein the Hall sensors sense the positionof the rotor of the motor and generate corresponding position information, the first circuit board is provided with a plurality of phase-change switch assemblies and a first controller, the second circuit board is provided with a second controller, the second controller can transmit corresponding driving information to the first controller according to the operation information of the operation interface, and the first controller can control the plurality of phase-change switch assemblies to change phases according to the driving information and the position information, so that the rotor of the motor rotates. Through the design that the commutation program and the user operation program are respectively processed by two different controllers, the program code of each controller can be effectively simplified, and the maintenance of the controller is facilitated.

Description

technical field [0001] The present invention is related to electric tools; in particular, it refers to the design of an electric tool which is beneficial for writing and maintaining program codes. Background technique [0002] Such as figure 1 and figure 2 As shown, a conventional electric tool 1 includes a housing 10, a motor 12, a Hall sensor 14, a controller 16, and a reversing switch assembly 18, wherein the housing 10 includes a transmission part 101 and a hand-held part 102, and the transmission part 101 A motor 12 and a driving mechanism (not shown) are arranged in the middle, the motor 12 is a three-phase DC brushless motor, and an operation interface 20 is arranged in the handheld part 102, and the operation interface 20 is operated by the user to generate an operation information. [0003] Wherein, the Hall sensor 14 is electrically connected with the controller 16, and the commutation switch assembly 18 is electrically connected with the motor 12 and the contro...
