Abstract

See full text

A power tool includes a casing with an inlet and an outlet extending in a radial direction of the casing, a motor installed within the casing between the inlet and the outlet. The motor includes a stator and a rotor with a shaft, an air passage being formed between a radially outer surface of the stator and an inner surface of the casing. The air passage extends in the axial direction of the casing. A heat dissipation device is arranged on the radially outer surface of the stator for absorbing heat from the stator, and is disposed in the air passage. A fan is fixed to the shaft of the rotor. Air flow generated by the fan enters the casing via the inlet and exits the casing via the outlet after passing through the air passage and the heat dissipation device.
