Abstract
A brushless motor comprises a rotor which is rotatable on an axis of the brushless motor and which include permanent magnets arranged circumferentially thereon, an output member connected to the rotor to rotate with the rotor, and a stator which includes electro-magnetic coils energized in order to rotate the rotor, and has a first space which receives the output member therein and a second space which extends from the first space to the outside of the stator so that an output power of the brushless motor is transmitted from the output member to the outside of the brushless motor through the second space.
