SOLUTION: A stator group is stator cores whose sectional forms are identical, and has a plurality of kinds of stator heights different in the number of laminated layers. A rotor group has one kind of diameter corresponding to a stator hole, and is provided with first rotor groups R1, R2, R3, R4 which use permanent magnets of residual magnetic flux density B, and second rotor groups R10, R20, R30, R40 which use permanent magnets of residual magnetic flux density 2B. Each stator height and each rotor height are set as integer times. The stator and the rotor which correspond to the respective set specification values of the set output torque specification value and the set rotor inertia specification value are selected and combined. Stators are made common, and cost can be reduced.

摘要： PURPOSE: To provide a cable clamp by which the extracting direction of a cable can be selected and by which the reliability of the extracting operation of the cable is enhanced by a method wherein the cable which has gone out from an opening for cable extraction is passed through a through port in a base part and the cable is extracted through a gap generated by a recessed part and by an upper lid. CONSTITUTION: A cable 4 which is extracted from a motor through an opening 31 for cable extraction is passed through a through port 11, and it is placed on any of four recessed parts 12. The cable 4 is extracted through a gap 22 for cable extraction when an upper lid 2 is slidden, and it is fixed firmly by the recessed part 12 in a base part 1 and the upper lid 2. Since the upper lid 2 can be slidden and inserted from any side of the base part 1, the extracting direction of the cable 4 can be selected easily from a required direction. In addition, even when an external force is applied to the cable 4, an extraction structure of high reliability can be formed because the cable 4 is fixed by the recessed part 12 and the upper lid 2.

摘要： PURPOSE: To ensure the distance of electric insulation between a wiring and an iron core without being an obstacle to the installation work of winding. CONSTITUTION: An insulating material 10, which electrically insulates a stator iron core 16 and a winding 16 from each other, is equipped with a main insulator 30 which directly covers the wall face (that is, the inside periphery 16a of a stator iron core 16, the side face 18a of a tooth 18, and one side face 24a of a hook 24) of a slot 20, and an auxiliary insulator 32 which substantially blocks the opening 26 of the slot 20, being extended in the direction of mutual proximity integrally from the regions of both margins of the main insulator 30 arranged in the opposite hooks 24 of adjacent teeth 18. The auxiliary insulator 32 has flexibility by which it is transformed relatively easily by external force, and also has repulsion to flexure, that is, firmness by which it restores to the original state at relatively slow speed after transformation, so that it may not hinder the installation work of the winding 22 to the slot 20 passed through the opening 26.

摘要： A fixed code plate carrying a light pickup element and a pattern of concentric slits is temporarily attached to the end of a motor housing. The housing is then turned about the motor shaft (14) and eccentricity of the slit pattern is referred to in order to centre the fixed code plate. The fixed code plate is permanently fixed to the housing, a clearance gauge being placed on the fixed code plate, and a sleeve together with a rotary code plate is put on the motor shaft and fixed. Alternatively, the rotary code plate is temporarily attached to the sleeve and is rotated to correct eccentricity before fixing.

CONSTITUTION:A plurality of metal plate discs 14 having spline type holes tightly engagable with the spline section 20 of an output shaft 12 are laminated to constitute a terminal board 13, then the terminal board 13 is fastened to the rotor body section 10 through a bolt 16 and a nut 18. The metal plate member is prepared by punching the profile, bolt holes and spline type holes through a member having punchable thickness in single process. Cutting work at the spline section 20 of the output shaft 12 is performed at the outer circumferential surface of the shaft. Consequently, machining can be facilitated and the number of the metal plate members 14 can be adjusted corresponding to the magnitude of transmission torque.

摘要： PURPOSE: To provide a rotor of synchronous motors that is simply manufactured without impairment of productivity and that effectively reduces slot ripples containing a wide variety of component. CONSTITUTION: A rotor 10 consists of a plurality of permanent magnets 14 that are placed on the circumference of a rotary shaft 12. A plurality of core members 16 that hold the individual permanent magnets 14 between them in the circumferential direction and that are placed on the circumference of the rotary shaft 12. Each of the core members 16 has a pair of sides 24 that extend in parallel with the axis A and are in contact with adjacent permanent magnets 14. A circumferential surface 28 that is opposed to a stator encircling the rotor 10. Each of the circumferential surfaces 28 has a convex curved shape between both sides 24, and the line segment L connecting their apexes extends at an angle α to the axis A in the direction of circumference. Each of the permanent magnets 14 is almost a rectangular parallelepiped that stretches the full length of the core member 16. Since the circumferential surface 28 of the core member 16 is linearly inclined, a wide variety of components in slot ripples that are produces during the rotation of the rotor 10, is effectively reduced.
