摘要： PROBLEM TO BE SOLVED: To provide a motor having a structure capable of arranging sufficient number of turns without adverse effects of magnetic saturation and avoiding upsizing thereof. SOLUTION: Respective steel sheets, forming a laminated body 10b for a stator core 10, of which outer-periphery edge section is bent aslant in an axial direction, so the radial length of the stator core 10 can be reduced while maintaining its quality. Thus, a motor can be downsized while maintaining its output quality by decreasing the outside diameter of the stator core 10. Where the outside diameter of the stator core 10 is provided with a fixed value, the outside diameter of a rotor core 50 can be increased by the amount of increase in the inside diameter of the stator core 10 as compared with the conventional cases, thereby improving the output torque quality of the motor without causing upsizing.

摘要： PROBLEM TO BE SOLVED: To effectively reduce leakage magnetic flux between stator teeth by inserting a nonmagnetic conductor to the aperture of a slot in the stator of motor, where a coil is inserted to a stator core with the slot. SOLUTION: A motor has a frame as a cylindrical casing, and a stator 10 is mounted to the internal circumference surface of the frame. The frame mounts a rotor via a bearing freely rotatably. The stator 10 has a stator core 11 and a coil wound around the stator core 11. The stator core 11 is formed, by laminating stator core single materials consisting of teeth 14 to form a magnetic circuit and a rear part of a core 15. The stator 10 inserts a nonmagnetic conductor 17 into an aperture 16 of the slot 13 of the stator core 11. Thereby, the leakage magnetic flux between the stator teeth 14 can be reduced effectively.

摘要： PROBLEM TO BE SOLVED: To increase the total torque of magnet torque and reactance torque by simple rotor structure by arranging a plurality of permanent magnets at regular intervals so that an angle formed between a (d) axis as the center of the magnetic force of the magnets and a (q) axis as the center of a core is less than 90 deg. at an electrical angle. SOLUTION: Four pairs of rmanent magnets 13 arranged in a fan shape towards the center of a rotor core 11 and flux barriers (flux interrupting sections) 14 are disposed. According to such arrangement, an angle formed between a (d) axis (the center of the magnetic force of magnets) and a (q) axis (the center of a core) is less than 90 deg. at an electrical angle. That is, the permanent magnets 13 are arranged near the (q) axis in the direction that the (d) axis is advanced in the rotor rotational direction R. Accordingly, since current phase in which magnet torque is maximized is shifted in the direction of current phase in which reluctance torque is maximized and the maximum point of magnet torque and the maximum point of reluctance torque are brought near, total torque is increased.
