Problems solved by technology

Among them, there are more connections between poles and phases in the form of stacked windings, and the embedding process is troublesome; while wave windings have fewer connections between poles and phases than stacked windings, but there are still connections between poles and phases
Moreover, when the winding form has the problem of connecting wires between poles and phases, not only long copper wires are required for connecting wires between poles and phases, but also the reliability of the joint connection is poor; therefore, for small and medium-sized motors, the armature current is relatively low. At present, it is a technical problem to be solved urgently to propose a new wire embedding method with high reliability and no need for inter-pole and phase-to-phase connections.

Embodiment 1

[0031] like Figure 1-6 As shown, the motor has 48 slots, the pitch is 1 to 7, the short pitch is 1 to 6, and the number of slots per pole and phase is 2. figure 1 Indicates the embedded line of the U phase, the other two phases are the same as the U phase, but the slot number is different.

[0032] like figure 1 As shown in the wiring diagram, the embedding steps are as follows:

[0033] S1: use first figure 2 The shown pitch coil 1 moves from the first slot to the left and starts to insert the wire for one week, and the order of the insertion is as follows: 1-43'-37-31'-25-19'-13-7' (the ones with 'indicate the lower layer coils edge); when the ruled line returns to the lower edge of the lower layer short-distance half-coil 3, use Figure 4 The short-distance half-coil 3 of the lower layer shown is moved to the right by 1 slot;

[0034] S2: continue to use figure 2 The shown pitch coil 1 moves to the left and inserts the wire again for one week, and the order of the ...

Abstract

The invention discloses a double-layer winding wire embedding method, wherein a double-layer winding comprises a pitch coil, an upper-layer short-distance half coil, a lower-layer short-distance halfcoil and a layer changing coil. According to the invention, armature wire embedding can be completed without interpolar wire connecting, the structure is simple, the operation is convenient, materialsand working hours are saved, reliability of the whole armature coil is improved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of wire embedding of motors, in particular to a method for embedding wires of double-layer windings. Background technique [0002] In the field of AC motor manufacturing, the winding form generally adopts lap winding or wave winding. Among them, there are more connections between poles and phases in the form of stacked windings, and the wire embedding process is troublesome; while wave windings have fewer connections between poles and phases than stacked windings, but there are still connections between poles and phases. Moreover, when the winding form has the problem of connecting wires between poles and phases, not only long copper wires are required for connecting wires between poles and phases, but also the reliability of the joint connection is poor; therefore, for small and medium-sized motors, the armature current is relatively low. At present, it is a technical problem to be solved urgently to propo...
