摘要： 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.

摘要： An electric motor for a blower and the like has a commutator and a brush assembly for making electrical contact with the commutator. The brush assembly includes a brush holder and a brush slidably mounted to the brush holder. The brush holder includes a brush holder plate and a side portion extending from the brush holder plate. The brush is arc-shaped and includes a first surface contacting the brush holder plate and a second surface contacting the side portion of the brush holder. The side portion of the brush holder has a number of ribs contacting the second surface of the brush.

摘要： An actuator for controlling an air damper includes a motor, an output connector for connecting the actuator to the air damper, a transmission mechanism connecting the motor to the output connector, and an energy storage device that drives the output connector to close the air damper when power to the motor is cut off. The motor has a stator and a rotor. The stator has a stator core including a yoke and nine poles extending from the yoke. The rotor has a shaft and an annular permanent magnet. The magnet forms twelve poles with alternate N and S polarities. An inclination angle of boundaries between adjacent poles of the magnet relative to an axis of the motor is in the range of 13 to 17 degrees.
