摘要： PROBLEM TO BE SOLVED: To provide an outer rotor type motor having a structure in which a jumper wire is attached by a simpler structure, and to provide a method with the motor further reduced in thickness.SOLUTION: A wear plate is extended in a center direction and ensures a space for attaching a jumper wire, and the jumper wire is attached to the extended portion, thereby reducing the thickness of the motor. Further, according to such a constitution, grease that leaks from an oil seal can be prevented from permeating the inside of the motor. Still further, the shape of the plate is devised for effective production management, and damages to the jumper wire are prevented.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet motor that has superior productivity and allows the same permanent magnet to be used in different motor outputs.
SOLUTION: A plurality of (here, ten) permanent magnets 3 are circumferentially arranged on the outer periphery of a rotor core 2 of a rotor 1 at equal intervals. Each permanent magnet 3 is formed such that K1 (here, K1=1) permanent magnet 3a with an axial length of L1 and K2 (here, K2=2, permanent magnets 3b
1 , 3b
2 ) permanent magnets 3b each with an axial length of L2 are axially arranged. Here, as the permanent magnet 3, the number (K1, K2) of permanent magnets 3a, 3b to be used is determined according to the motor output. Accordingly, the number of magnets may be only one permanent magnet 3a1, or only one permanent magnet 3b1. In such a manner, only two types of permanent magnets 3a, 3b may be used to obtain permanent magnet motors that have different motor outputs while having the same cross-sectional shape and the same cross-sectional area.

摘要： PROBLEM TO BE SOLVED: To provide a permanent magnet synchronous motor which can reduce torque reduction due to magnetic saturation occurring at a large current and also can reduce a loss and increase in heat generation caused by a current increase, through the application of a stator structure suitable for driving at a low speed, a large torque and a large current.
SOLUTION: The permanent magnet synchronous motor is configured such that the slot width is constant relative to the radial direction, the slot bottom is arc-shaped to have a half length of the slot width as its radius, and a magnetic pole piece extending in the circumferential direction from the teeth inner circumferential end toward the center of the slot width. Thus, the leakage in the magnetic flux of the slot can be reduced to be used as an effective magnetic flux, so that a permanent magnet synchronous motor with a high torque and high performance can be provided.
