摘要： This invention is to provide a low-cost structure that a cogging torque and a torque ripple are small and a stable rotation is provided in a radial gap type motor.A portion that stator pole teeth 37 to become interpoles are provided between stator poles 38 and a plurality of stator pole teeth 37 are not continuously provided between the partial stator poles 38 is provided. As a result, in this invention, a magnetic attraction force between the stator pole teeth 38 and the rotating pole 9 of a rotor 6 is stronger in the case that the pole teeth 37 are provided than in the case that the pole teeth 37 are not provided.Accordingly, the rotational shaft 12 of the rotor 6 is supported at three points of points P, Q and R of the bearing cylinder 4, and a rotary force is received at the point P as a center. As a consequence, the rotational shaft 12 is rotated with less contact friction with the bearing cylinder 4.

摘要： There is provided a storage device whose cost is greatly reduced by employing a low-cost claw-pole two-phase synchronous motor as a spindle motor in which the rotation nonuniformity and vertical fluctuation of its shaft are suppressed while suppressing the leakage magnetic flux, by employing an open-loop scheme for motor control, and by mounting a drive circuit on the side of a control LSI for controlling the device to omit a motor control drive circuit (driving IC). The number of basic steps of the claw-pole two-phase synchronous motor is set to 48 steps or more. Stator pole teeth between both sub-assemblies are located within the range of 90.degree..+-.5.degree. in electrical angle. One end surface of a rotor having a field magnet is subjected to index magnetization also serving as rotor chuck magnetization. A magnetic shield plate is arranged on the surface of the rotor opposite to the magnetic head. The claw-pole two-phase synchronous motor having the above arrangement is used as a spindle motor, thereby realizing a low-cost storage device having a simple motor drive circuit by open-loop control.
