摘要： A small motor for use in an information-communication appratus, an audio-visual apparatus or the like, and a motor for use in a portable pager and a portable telephone or the like for generating vibrations to be transmitted to a human body, the motors being efficient, small and thin in size, and having a high degree of freedom when mounted on an apparatus. To realize the motor as described above, K pieces of (K indicating any integer greater than one) magnetic units (4a, 4b, 4c) having N and S poles magnetized alternately are mounted on a rotor in a circumferential direction, and K magnetic units are axially stacked in K stages and integrally retained on a shaft (6), and this rotor is rotatably supported on a pair of bearings (9a, 9b). Cores (1a, 1b, 1c) each have a salient pole (7a, 7b, 7c) wound around with coils (3a, 3b, 3c) in K stages so as to correspond to each of the magnetic units. The magnetized position of the N and S poles of the magnetic unit at each stage deviates relative to one another in a circumferential direction so as to set the phase of induced voltage generated on the salient pole wound around with the coil in each stage to a phase suitable for rotating a magnet unit corresponding to a coil in that stage.

摘要： In manufacturing of the stator unit 2 according to one preferred embodiment of the present invention, a plurality of terminal pins are arranged in an axially spaced manner from a plurality of the coils during a twining process of the wires from the coils 232 to the terminal pins 241. Then, after the wire is twined to the terminal pins, the terminal pins connected to the coils are moved along the outer side face of the sleeve housing, functioning to as a guide portion for the terminal pins. By virtue of the configuration, the terminal pins 241 may be approximated to the coils without applying the tension on wire, and the stator unit may be made thin with preventing the open circuit of the wires.

摘要： A spindle motor has a tapped hole formed in the end surface of a rotor hub at the center of rotation of the rotor hub. A clamping member presses a disk against a disk holding surface of the rotor hub by a clamp screw threaded in the tapped hole. Since the disk is clamped through a clamping member by threading and tightening one clamp screw, the clamping operation is efficiently carried out and disk imbalance due to the clamping clamp screw is decreased.
