Abstract

An electric tool includes a casing, a motor, multiple hall sensors, a first circuit board and a second circuit board. The plurality of Hall sensors sense the rotor position of the motor and generate corresponding position information; the first circuit board is provided with a plurality of reversing switch assemblies and a first controller; the second circuit board is provided with a second controller, and 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 multiple phase-changing switch assemblies to perform phase-changing according to the driving information and the position information, so that the The rotor of the motor rotates. Through the design of the present invention that the phase change program and the user operation program are processed by two different controllers, the program codes of each controller can be effectively simplified, and the maintenance of the controllers is facilitated.

Description

technical field [0001] The present invention relates to electric tools; in particular, it refers to a design of electric tools which is beneficial to writing and maintaining program codes. Background technique [0002] like figure 1 and figure 2 As shown, the conventional power tool 1 includes a casing 10 , a motor 12 , a Hall sensor 14 , a controller 16 and a commutation switch assembly 18 , wherein the casing 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 motor 12 , the motor 12 is a three-phase DC brushless motor, and an operation interface 20 is arranged in the hand-held part 102 , and the operation interface 20 is operated by the user to generate an operation information. [0003] The Hall sensor 14 is electrically connected to the controller 16 , and the commutation switch assembly 18 is electrically connected to the motor 12 and the controller 16 respect...
