Title:
CONNECTION STRUCTURE OF SINGLE-PHASE FOUR-POLE SERIES MOTOR, AND SINGLE-PHASE FOUR-POLE SERIES MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/051890
Kind Code:
A1
Abstract:
A connection structure (100) of a single-phase four-pole series motor, comprising four excitation windings (11, 12, 13, 14) evenly distributed around a stator, an armature winding (20) sheathed on a rotor, and four brushes (31, 32, 33, 34), the four excitation windings form two N poles and two S poles, and the N poles and the S poles are adjacent to each other in pairs, two left and right diagonal excitation windings are connected in parallel to form a first S-pole excitation winding assembly by means of corresponding brushes, two front and rear diagonal excitation windings are connected in parallel and form a second N-pole excitation winding assembly by means of corresponding brushes, and the first excitation winding assembly and the second excitation winding assembly are both connected to the armature winding in series.
