WIPO Patent Application WO/2016/082701

Kind Code:

A1

Abstract:

An electric tool control circuit comprises a central control module, a motor drive module, a motor, and a working parameter detection module. The working parameter detection module is separately electrically connected to the motor and the central control module, and the working parameter detection module can return a parameter that is detected when the motor works to the central control module. The motor drive module is separately electrically connected to the motor by using first and second switch modules, and the motor drive module controls the first and second modules to be discontinuously on and off. The features of the first switch module and the second switch module being on and off are always contrary, that is, when a first switch is on, a second switch is off, and when the first switch is off, the second switch is on.
