Motor stator and motor

Abstract

The invention provides a motor stator and a motor. The motor stator comprises a stator winding, wherein each phase winding at least comprises a conductor group, each conductor group comprises a long cross-layer conductor which radially crosses a G layer in two grooves, G / 2 consequent adjacent cross-layer conductors in the same radial cross-layer direction as the long cross-layer conductors and G / 2-1 inverse adjacent cross-layer conductors in the opposite radial cross-layer direction as the long cross-layer conductors are arranged between the radial cross-layers of the long cross-layer conductors, and G is larger than or equal to 4 and smaller than or equal to M; and the interiors of the two grooves of the rest conductors except the long cross-layer conductor in each phase winding are positioned on two adjacent layers in the circumferential direction of a stator core. By adopting the motor stator, a gap bridge line is omitted, heat dissipation is uniform, power and torque are improved, the wiring mode is simplified, the process is simplified, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor stator and a motor. Background technique [0002] The stator winding includes a plurality of hairpin coils, and the multiple hairpin coils are inserted into the slots of the stator core according to a certain arrangement to form the single-phase winding or multi-phase winding of the required motor. The hairpin coils used in the prior art There are many types, so the stator winding needs to use a large number of bridge wires to connect the branches of each phase winding, the arrangement of the stator winding is complicated, the forming is difficult, the production cost is high, and the processing efficiency is low. Contents of the invention [0003] The main purpose of the present invention is to provide a motor stator and motor, eliminating bridge wires, uniform heat dissipation, increased power and torque, simplified wiring methods, further simplified processes, and improved proc...
