摘要： Provided is a motor including a shaft; two rotors attached to the shaft and spaced from each other in an axial direction by a predetermined distance; a stator arranged between the two rotors; a busbar unit arranged on one axial side of at least one of the two rotors, and arranged to hold a busbar; and a housing arranged to hold the stator and house the two rotors therein. The stator includes a plurality of cores arranged in a circumferential direction, and coils wound around the cores. A lead wire drawn out from the coils is arranged to extend, radially outside of the one of the rotors, from the corresponding core to a position on the one axial side of the one of the rotors, and is connected to the busbar at the position. The busbar unit is housed in the housing.

摘要： A motor may include a stator having coil groups of plural phases and a connector, the stator comprising a plurality of split stators. Each of the split stators may include a split core having an arc-shaped core back section and a tooth section, an insulator, a coil which has a lead-out line that is connected to the connector. The insulator may have a first void extending between a first inner wall and a first outer wall. The first inner wall may have a lead-in groove. The stator may have a support ring disposed on the upper side of the first void. The support ring may have a second void extending between a second inner wall and a second outer wall. A plurality of lead-out lines of different phases may respectively accommodated in the first void and the second void.
