Stator winding structure of low-speed oil submersible motor

The invention relates to a stator winding structure of a low-speed oil submersible motor, which is characterized in that beginning end stator grooves arrayed according to phase sequences A, B and C of three phases of windings and corresponding tail end stator grooves X, Z and Y sequentially have a difference of a space angle of 60 degrees, and each unit winding from the beginning end of an inlet groove to the tail end of an outlet groove of each phase of the windings has the following trend, the connection and the distribution of upper layers and lower layers that a lower inlet line of a 0 degree groove of the beginning end, a lower outlet line of a -140 degree groove, a connecting line, a lower inlet line of a -40 degree groove, a lower outlet line of the -140 degree groove, a connecting line, a lower inlet line of a +40 degree groove, an upper outlet line of a -120 groove, a connecting line, a lower inlet line of a -60 degree groove and an upper outlet line of a -120 degree groove.
