Abstract
A power tool includes a brushless motor having a stator and a rotor. The stator includes a stator core having teeth, first and second insulators fixed to the stator core, and coils respectively wound around the teeth, all of the coils being wound around the first and second insulators. The rotor includes a rotor core disposed in the interior of the stator, a rotary shaft fixed to the rotor core, and one or more permanent magnets fixed to the rotor core. Power supply lines are configured to respectively supply current to the coils. Fusing terminals are fixed to the first insulator members. The fusing members respectively pinch the power supply lines and are thereby respectively electrically connected to the power supply lines.
