Abstract: Provided is a motor in which the interference between systems can be suppressed even when the number of pole pairs is odd. The motor according to one embodiment of the present disclosure is a three-phase AC motor provided with two-system stator windings to which voltages are applied by inverters different from each other and each of which has a plurality of coils, wherein said stator windings are ubiquitous in the circumferential direction so that the number of said coils disposed overlapped with said coils of the other system is reduced.

Abstract: A stator of a rotary electric machine comprises: a stator core including multiple slots; multiple coils formed using a winding wound in a distributed fashion so as to pass through the slots; and multiple power lines connected to the coils. The coils have a coil end projecting from an end surface of the stator core. The coils are adjacent to each other in the peripheral direction. A connection between each of the coils and a corresponding one of the power lines is arranged adjacent to a base portion of the coil end on the outer periphery. Each of the power lines starts from the connection to extend along the outer periphery of the coil end to be adjacent to the base portion of the coil end on the outer periphery while extending outwardly in the axis direction from between the coils adjacent to each other in the peripheral direction.

Abstract: A squirrel-cage rotor of an induction motor and a production method thereof, wherein locating of the brazing material is not necessary in order to reduce manhours for brazing, and a bar is easily connected to an end ring. Before assembling a rotor core, a silver plated layer is formed on at least one of an end ring and a conductive bar. In order to melt the silver plated layer, the rotor is heated to a temperature which is equal to or larger than the melting point of the silver plated layer. The melted layer functions as a brazing material, whereby the end ring and the conductive bar are connected.
