Patent ID: 7511398

Claim:
A motor comprising: a rotor section rotatable about a center axis and including a rotor magnet; a stationary section including a stator and a base portion which is disposed axially below the stator, wherein the stator is opposed to the rotor magnet in a radial direction substantially perpendicular to the center axis and includes a supporting ring fixed to the base portion, a plurality of teeth extending from the supporting ring toward the rotor magnet and each having a radial end facing the rotor magnet, and a coil formed by a wire wound around a portion of each tooth, wherein the portion of each tooth having the wire wound there around defines a wire wound portion of each tooth; and a bearing section operable to support the rotor section in a rotatable manner relative to the stationary section, wherein the supporting ring and the teeth are integral with each other, and the wire-wound portion of each tooth is axially depressed in a direction towards the base portion between the supporting ring and the radial end of the tooth such that an axially lower surface of the entire wire-wound portion of each tooth is lower than an axially lower surface of the supporting ring and an axially lower surface of the radial end of the teeth, the base portion has a receiving portion which receives a portion of the stator therein such that an axially lower end of the coil and the axially lower surface of the wire-wound portion of each tooth are located between an axially upper surface and an axially lower surface of the base portion.
