Abstract: A power tool includes a main body and a working portion. The working portion is rotatably coupled to the main body. A single phase brushless motor is mounted in the main body to drive the working portion to rotate bidirectionally. In comparison with a traditional motor, the single phase brushless motor make the power tool has a reduced size and reduced cost while ensuring the stable performance.
