Big wire casing C, the B of two inclinations, and angle is Ω=10.5 ° between the stator center radial transmission line, ω=11 °;

External diameter b=128 ± the 5mm of stator, external diameter width a=123 ± 5mm, internal diameter c=76 ± 3mm, wire casing B top diagonal distance e=105 ± 5mm, wire casing C top diagonal distance f=103 ± 5mm, wire casing D top diagonal distance d=93.5 ± 5mm, wire casing A top diagonal distance g=104 ± 5mm;

The widest part h=6.8 ∽ 7.6mm of wire casing A, the narrowest L=3.6 ∽ 4.3mm of place, A/F K=1.9 ∽ 2.5mm, bore degree of depth i=1.3 ∽ 1.8mm, j=0.8 ∽ 1.2mm;

The widest part m=6.2 ∽ 7.0mm of wire casing B, the narrowest place is n=3.2 ∽ 3.9mm, A/F O=1.9 ∽ 2.5mm;

The widest part p=5.1 ∽ 5.9mm of wire casing C, the narrowest r=4.7 ∽ 5.3mm of place, A/F are 1.9 ∽ 2.5mm;

The widest part q=3.2 ∽ 3.9mm of wire casing D, A/F u=1.9 ∽ 2.5mm, bore degree of depth t=1.3 ∽ 1.8mm, s=0.8 ∽ 1.2mm.

The utility model has the advantages that, reach equal motor power output, both saved copper material, alleviated the weight of motor again, and reduced this cost, killing three birds with one stone.
