Electric tool and electric tool control method

The embodiments of the invention disclose an electric tool and an electric tool control method. The electric tool comprises a motor used for driving a functional part in the electric tool to rotate, a driving circuit connected with the motor and used for switching the power-on state of a phase winding in the motor, and a controller connected with the driving circuit, and used for outputting a control signal to the driving circuit to control the motor to work and adjusting the lead angle of the motor according to the preset type of load working parameters of the motor in the electric tool. According to the electric tool provided by the embodiment of the invention, the controller determines the load state of the electric tool by acquiring the load working parameters of the motor, and further adjusts the lead angle of the motor according to the load working parameters of the electric tool so as to adjust the rotating speed of the motor; and therefore, the rotating speed of the motor is matched with the load stat
