    • 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 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.
    • 一种电动工具控制电路,包括中央控制模块,电机驱动模块,电机以及工作参数检测模块。 工作参数检测模块分别与电机和中央控制模块电连接,工作参数检测模块可以将电机工作时检测到的参数返回中央控制模块。 电机驱动模块通过使用第一和第二开关模块分别电连接到电机,并且电机驱动模块控制第一和第二模块不连续地打开和关闭。 第一开关模块和第二开关模块的通断特性总是相反的,即当第一开关接通时,第二开关断开,并且当第一开关断开时,第二开关接通。
