Abstract:
A DC brushless motor structure comprising:a base comprising a through-hole and a wall, at least two sets of windings being mounted to the wall of the base, an IC control means being mounted on the base and electrically connected to said at least two sets of windings; and a rotor comprising a shaft and a permanent magnet having a north pole and a south pole, the shaft being rotatably received in the through-hole of the base, the permanent magnet surrounding the base, a repulsive magnetic force is directly created between the permanent magnet and said at least two sets of windings, thereby driving the rotor to turn, wherein the through-hole of the base has an inner diameter greater than an outer diameter of the shaft of the rotor, the through-hole has a first end and a second end, a support member being mounted in the first end of the through-hole, a lid being engaged with the second end of the through-hole and having an axle hole through which an end of the shaft extends, the supporting member supporting another end of the shaft.
