摘要： The present invention is directed to a movable body driving mechanism including a first frame and a second frame that is capable of moving relative to the first frame. The movable body driving mechanism includes a cam groove that is formed in the first frame, and a cam follower that is formed in the second frame and inserted movably in the cam groove. The cam groove includes a plurality of regions having different widths. The cam follower is formed to have a shape with a plurality of outer diameters, and different parts of the cam follower contact an inner lateral surface of the cam groove in each of the plurality of regions. With this configuration, the lateral surface of the cam follower can be made to contact the lateral surface of the cam groove constantly, thus achieving the cam driving without looseness. Also, since the biasing means or the like is not needed, it is possible both to simplify the configuration and to reduce the number of manufacturing steps.

摘要： A motor generating cogging torque has one-quarter the cycle of basic cogging torque and an extremely small absolute value. First, in order to reduce the cycle of the cogging torque to one-half the cycle of the basic cogging torque, a basic configuration of the core is determined by setting opening angles of its slots to an appropriate electrical angle ranging from 80° to 95° and from 20° to 35°. Next, to produce the above-mentioned effects, an angular displacement of one-quarter the cycle of the basic cogging torque is provided in the motor. Furthermore, polarizing the core with a skew angle equal to one-half or less the cycle of the basic cogging torque at the same time allows the cogging torque to be reduced effectively while decrease in efficiency is minimized.

摘要： In a conventional blowing apparatus, vibration is increased depending upon a combination of rotor magnetic poles, the number of stator salient poles and blades of a fan. In a blowing apparatus comprising a stator having a core including a M-number of salient poles, and a rotor having permanent magnets having a P-number of magnetic poles rotatably disposed such as to be opposed to magnetic pole surfaces of the stator, the stator and the rotor, in combination, forming a motor for rotating a fan having a N-number of blades, mN≠nM or mN≠nP is satisfied. With this feature, a synergism between vibration generated by cogging torque of the motor and vibration generated by rotation of the fan is moderated, and vibration and noise are reduced.

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.
