Title:
THREE-PHASE MOTOR WINDING PATTERN STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/231002
Kind Code:
A1
Abstract:
The present invention relates to a three-phase motor winding pattern structure comprising: a stator core having multiple slots; and a stator coil wound around the stator core by using multiple conductor segments. Each of the multiple conductor segments may be formed in a hairpin type so as to have a quadrangular sectional shape and to have a U-shape that is open in one direction. In connection with the stator coil, on the nth layer positioned on the outermost part along the radial direction of each of the multiple slots, a short-pitch conductor segment, both sides of which are spaced apart by an interval of (reference slot pitch – one slot pitch), and a long-pitch conductor segment, both sides of which are spaced apart by an interval of (reference slot pitch + one slot pitch), may be arranged in a row. On the second to (n-1)th layers positioned between the outermost part and the innermost part of the slots, (n-2)/2 pairs of normal-pitch conductor segments, both sides of which are spaced apart by the reference slot pitch interval, may be arranged on different layers. On the first layer positioned on the innermost part of the slots, a pair of normal-pitch conductor segments, both sides of which are spaced apart by the reference slot pitch, may be arranged in a row.
