摘要： An electric power tool includes: a motor; an operation unit; a control parameter setting unit; and a control unit. The control parameter setting unit sets, as a control parameter of the motor, an optimum maximum rotational speed of the motor corresponding to a predetermined set torque or a control amount corresponding to the optimum maximum rotational speed. The control unit is configured to drive the motor in response to an operation amount of the operation unit and to control a rotational speed of the motor at or smaller than the optimum maximum rotational speed based upon the control parameter. The control parameter setting unit determines, as the optimum maximum rotational speed, a rotational speed of the motor that rotates with a rotational energy required to rotate the output shaft at the set torque and sets the optimum maximum rotational speed as the control parameter.

摘要： An electric power tool includes a motor, a current detection unit, an operating portion, a current threshold setting unit and a control unit. The current threshold setting unit sets a current threshold so as to change in accordance with changes in a motor current which flows when the motor is started as usual until a predetermined period of time elapses since the control unit has started driving of the motor. When the predetermined period of time has elapsed, the current threshold setting unit fixes the current threshold to a constant value which corresponds to a set torque.
