Patent ID: 8154162

Claim:
A motor for holding a disk with a mounting opening in place, comprising: a rotor unit including a rotor magnet rotatable about a central axis; and a stator unit including a stator arranged opposite to the rotor magnet and a circuit board electrically connected to the stator, wherein the stator includes a plurality of coils made of a conductive wire and arranged to generate magnetic fields, said plurality of coils creating a neutral point and end portions, wherein the circuit board is provided with wiring lines electrically connected to the coils, wherein the wiring lines comprise: output-side land portions, each electrically connected to one of the end portions; a connection-side land portion electrically connected to the neutral point; first connection portions and a second connection portion, each electrically connected to an external power source or an external circuit board; output-side wiring portions, each arranged to electrically interconnect each of the output-side land portions and each of the first connection portions, and a connection-side wiring portion arranged to electrically interconnect the connection-side land portion and the second connection portion, and wherein each of the output-side wiring portions has a width greater than a width of the connection-side wiring portion, wherein the connection-side wiring portion is extended from the second connection portion at a direction opposite to the direction at which the output-side wiring portions are extended from the first connection portions.
