A hollow brushless motor is provided. The hollow brushless motor includes a hollow shape rotor to be rotatable about a rotation axis, a hollow shape stator spaced apart from the rotor by a distance in a direction of the rotation axis and arranged to face the rotor, and a first support to maintain a gap between the rotor and the stator, and arranged between the rotor and the stator to support the rotor and the stator such that the rotor rotates with respect to the stator.
