Patent ID: 8333259

Claim:
A motor comprising: a stator that includes a plurality of winding wires wound thereon; a rotor rotatably disposed within an inner radius of the stator; a shaft coaxially disposed to be rotatable with the rotor; a magnet disposed on one end of the shaft to be rotatable with the rotor and the shaft; a magnetic sensor disposed in an axial direction of the shaft for detecting a rotation angle of the rotor by sensing the magnetism generated by the magnet; a control unit for controlling an electric power supplied to each of the plurality of the winding wires based on the rotation angle of the rotor detected by the magnetic sensor; and a first conducting wire and a second conducting wire (a) respectively intersecting with a virtual circle that centers around an axis of the shaft and (b) respectively extending in parallel with the axis of the shaft, for connecting the control unit to each of the plurality of winding wires, wherein the electric current flowing in each of the first conducting wire and the second conducting wire has a same magnitude and a same flow direction with each other at any point of time, and a position of the first conducting wire and a position of the second conducting wire satisfy a relationship α=180, when (a) an intersection of the first conducting wire with the virtual circle is designated as a point p 1 , and an intersection of the second conducting wire with the virtual circle is designated as a point p 2 , and (b) a central angle of an arc between the point p 1 and the point p 2 on the virtual circle is designated as α degree.
