摘要： A stator includes an annular stator core, and a coil formed of a plurality of electric wires having a conductor and an insulating film covering the conductor, and having a conductor exposed portion which protrudes in an axial direction of the stator core and in which the conductor is exposed at an end portion of each of the electric wires, and a coupling portion in which a distal end of the conductor exposed portion in one electric wire and a distal end of the conductor exposed portion in another electric wire are coupled. The conductor exposed portion of the electric wire is formed as a curved portion that is curved as a whole.

摘要： A stator includes a stator core, and a coil mounted on the stator core and having an insulating film, at least a part of the insulating film being coated with a protective paint, wherein the insulating film has a vacancy, and the vacancy is formed by a hollow capsule. In addition, the protective paint has a powder, and an internal form of the vacancy is smaller than an external form of the powder.

摘要： In a stator constituting a rotary electric machine, a U-shaped first and second divided conductors are disposed at slots. The pitch of a pair of straight parts of the first divided conductor is set larger than that of a pair of straight parts of the second divided conductor. The second divided conductor is disposed on the inner side of the first divided conductor, more specifically, on the stator core side.

摘要： A rotary electric machine control system includes a rotary electric machine, a rotation speed sensor, a temperature sensor, and circuitry. The rotary electric machine includes a rotor. The rotation speed sensor is to detect a rotation speed of the rotor. The temperature sensor is to detect a temperature of the rotary electric machine. The circuitry is configured to classify an operation time during which the rotor rotates based on the rotation speed detected by the rotation speed sensor and the temperature detected by the temperature sensor. The circuitry is configured to calculate a fatigue degree of the rotor based on the operation time classified. The circuitry is configured to limit the rotation speed of the rotor or output a signal to a user when the fatigue degree exceeds a threshold value.

摘要： One embodiment provides an electric rotary machine unit including: a first electric rotary machine having a first stator; and a second electric rotary machine having a second stator. A coil configured by plural coil segments is disposed in each of the first and second stators. The first and second stators are disposed so that connecting portions of the coil segments or joint portions of leg portions of the coil segments are positioned between the stator cores thereof. First and second feeding portions are interposed between the first and second stators in the axial direction and spaced apart from each other in the circumferential direction.
