Abstract: <P>PROBLEM TO BE SOLVED: To control torque-rotation speed characteristics of a motor to achieve an optimum operational efficiency.  <P>SOLUTION: Current is inputted from the rotating motor 14 to a current detection section 34. The voltage of a rechargeable battery 12 is inputted to a voltage control section 36. The voltage control section 36 outputs a drive voltage corresponding to the optimum rotational frequency of the motor 14 to a motor driver 13 based on the inputted voltage and the current inputted to the current detection section 34. That is, it corresponds to the optimum rotation speed irrespective of the charged condition or load torque of the rechargeable battery, and therefore an impact screwdriver fastens different types of screws as well most efficiently. Accordingly, the motor is controlled based on a load current proportionally related to the load torque and the voltage of the rechargeable battery 12. Hence the motor drive voltage can be suitably varied depending on the load torque, namely, the optimum rotation speed corresponding to a screw load, and the torque-rotation speed characteristics of the motor in response to the power tool can be controlled to achieve the optimum operational efficiency.  <P>COPYRIGHT: (C)2010,JPO&INPIT
