Abstract
An electric tool includes a motor, a drive shaft, a torque sensing module, and a control device. A control method of the electric tool includes: driving the motor to rotate a rotating shaft in a direction of rotation through the control device; driving the motor in a plurality of first start-stop cycles through the control device when the control device determines that an increase in the torque sensed by the torque sensing module; driving the motor in a plurality of second start-stop cycles through the control device when the control device determines that the torque sensed by the torque sensing module has increased to a first predetermined torque and is less than a second predetermined torque. Therefore, in the process of tightening or loosening a workpiece, the discomfort felt by the hands of the user due to reaction forces during increasing the torque could be effectively reduced.
