Document Type and Number:
WIPO Patent Application WO/2014/115650
Kind Code:
A1
Abstract:
A coil winding structure wherein: a U-phase coil (U1 - U6) is formed on each tooth corresponding to a U phase so as to be formed in a series so as to form a U-phase coil group (UC); a V-phase coil (V1 - V6) is formed on each tooth corresponding to a V phase so as to be formed in a series so as to form a V-phase coil group (VC); a W-phase coil (W1 - W6) is formed on each tooth corresponding to a W phase so as to be formed in a series so as to form a W-phase coil group (WC); the U-phase coil group (UC), V-phase coil group (VC), and W-phase coil group (WC) are connected in series; and input/output units (31a, 31b, 31c) are disposed in each phase coil group (UC, VC, WC) in a manner such that between two input/output units two phases of coils of differing quantity are present.
