ELECTRIC POWER TOOL
First Claim
1. An electric power tool comprising:
- a power supply;
a motor including a drive shaft;
a tool output shaft configured to be driven based on a torque of the drive shaft of the motor;
a voltage step-up condition setting operation unit that serves as a human machine interface;
a voltage converter capable of performing a voltage step-up operation to raise a voltage supplied from the power supply and supply a raised voltage to the motor, the voltage converter being capable of changing a voltage step-up level in the voltage step-up operation in accordance with the operation of the voltage step-up condition setting operation unit;
a driving state detection unit configured to generate a driving state signal corresponding to a driving state of the electric power tool; and
a control unit configured to control a stop timing of the motor in accordance with the driving state signal.

Abstract
An electric power tool includes a voltage step-up condition setting operation unit that serves as a human machine interface and a voltage converter capable of performing a voltage step-up operation to raise a voltage supplied from a power supply and supply a raised voltage to a motor. The voltage converter is further capable of changing a voltage step-up level in the voltage step-up operation in accordance with the operation of the voltage step-up condition setting operation unit. A driving state detection unit generates a driving state signal corresponding to a driving state of the electric power tool. A control unit controls a stop timing of the motor in accordance with the driving state signal.
