部とからなることを特徴とする電動ドライバー。 In an electric screwdriver that consists of a power supply body and a driver body, the power supply body compares and controls the rotation speed and torque curve recorded in the memory section with the rotation speed and current of the DC motor converted into digital signals by the A/D conversion section. The driver body consists of a calculation section and a motor control section that controls the rotational speed and torque of the DC motor using control signals from the comparison calculation section, and the driver body includes a DC motor section that converts the control signals from the motor control section into rotational force. and a reduction gear section that converts the rotational force of the DC motor section into predetermined rotation and torque;
an electromagnetic clutch section that transmits and interrupts the rotational torque converted by the reduction gear section to the driver bit section; a twist detection section that detects twist of the driver bit section and transmits the detected twist to the A/D conversion section of the power supply section;
An electric screwdriver comprising a rotation detecting section and a current detecting section that detect the rotation speed and current of a DC motor section and transmit the detected values to an A/D converter section of a power supply section.
