回転電機ステータ
Document Type and Number:
Japanese Patent JP7000170
Kind Code:
B2
Abstract:
To reduce the number of welding points required for connection between in-phase coil groups and power lines when a stator coil includes two sets of Y-connected three-phase coil groups in a rotary electric machine stator.SOLUTION: A rotary electric machine stator includes: a stator core having a plurality of teeth; a stator coil which includes two sets of Y-connected three-phase coil groups, where each coil group has a plurality of coils wound around and connected in parallel with the plurality of teeth; and power lines on a power supply side connected with connection ends of drawing lines provided at ends of the coil group of each phase in each set, and drawn to extend radially outside on the outside in an axial direction of the stator core. At least one drawing line of the two drawing lines which are drawn from the in-phase coil groups is bent to approach the connection end of the other drawing line at an end of the outside in a radial direction, and the connection ends of the two drawing lines are directly welded to the power lines.SELECTED DRAWING: Figure 4
