Document Type and Number:
Japanese Patent JP7038026
Kind Code:
B2
Abstract:
Rotating machinery includes a 2n-pole rotor (100), a stator core (10) with 72n slots (50), and three-phase armature windings (n is integer and ≥1). Each of the armature windings has 2n phase belts (60) per phase. Each of the phase belts (60) includes a first parallel winding and a second parallel winding. The first and second parallel windings are arranged in the stator slots (50) as top coils (20) and bottom coils (30). Assuming that a circumferential mean position of all top coils (20) and bottom coils (30) included in each of the phase belts (60) is defined as a phase belt center (60a), an arrangement of the first and second parallel windings in at least one phase belt (60), as viewed in an order of proximity to the phase belt center (60a), is such that the first and second parallel windings are arranged in an order of the second, first, second, first, first, second, first, second, first, second, second, and first parallel windings as the top coils (20), and the first and second parallel windings are arranged in an order of the first, second, second, first, second, first, first, second, first, second, second, and first parallel windings as the bottom coils (30) connected to the top coils (20).
