Patent ID: 7825550

Claim:
A brushless motor comprising: an armature comprising a core back, a plurality of teeth extended from the core back, said plurality of teeth being arranged in a radial manner centering about a central axis, a coil formed by winding a magnet wire around each of the plurality of teeth, and a spacer connecting at least the circuit board and the core back, or the circuit board and the plurality of teeth in the axial direction; a rotor portion including a rotor magnet generating between the armature a torque centering about a central axis, the rotor portion rotates relatively with respect to the armature centering about the central axis; a base portion supporting the armature in a fixed manner; and a circuit board arranged between the armature and the base portion, and configured thereon a circuit controlling a rotation of the rotor portion, wherein the spacer includes a hook portion; the magnet wire extracted from the coil is hooked on the hook portion and is further extended and electrically connected to the circuit board at the end of the magnet wire, the magnet wire being bent at the hook portion toward a direction different from a direction in which the magnet wire extends off the coil; and a tension applied to a portion of the magnet wire between the hook portion and the end is smaller than that applied to a portion of the magnet wire between the coil and the hook portion.
