Technical field
The present invention relates to a kind of intermediate frequency permanent magnet AC motor winding, especially a kind of intermediate frequency magneto Three-phase Single-layer Windings.
Background technology
The intermediate frequency magneto has become the developing direction of energy-saving electric machine, but the general number of poles of intermediate frequency magneto is many, and the groove number is few.And every extremely every phase groove number mostly is fractional-slot, when the three-phase design of Windings is double-deck short distance winding in this motor, because that the double hyer insulation material accounts for groove area is many, makes the winding copper factor little.Motor is uneconomical, and when being designed to traditional single layer winding because of mostly being the range winding, the harmonic content that contains in the magnetic potential of winding is big, motor performance such as efficient, noise, vibration, waveform etc. all are adversely affected.Seek a kind of novel winding, make the copper factor height, winding overhang is short, mmf wave is tending towards sine-shaped Three-phase Single-layer Windings with short pitch, make it can obtain the good characteristic of double-deck short distance winding, can obtain the high usage of groove volume again, this has very realistic meanings in multipole mid-frequency motor.
Summary of the invention
The purpose of this invention is to provide a kind of intermediate frequency magneto Three-phase Single-layer Windings with short pitch.
The present invention is achieved like this, and it is characterized in that working as the groove number is 36 grooves, when number of poles is 14 utmost points, the number of phases is 3 phases, every is that the series connection of 3 circle coils such as standard-sized sheet mouth forms three symmetrical short pitch single layer winding by 6 coil Y=1-4 pitches, and wherein A is arranged in groove 14,17 mutually; 20,23; 24,27; 30,33; 34,1; Spider lable A in 4,7 ten two grooves, X; B is arranged in groove 26,29 mutually; 13,35; 36,3; 6,9; 10,13; Spider lable B in 16,19 ten two grooves, Y, C are arranged in groove 2,5 mutually; 8,11; 12,15; 18,21; 22,25; Spider lable CZ in 28,31 ten two grooves, three phase windings can be connected into Y, Δ; When the groove number is 36 grooves, when number of poles was 10 utmost points, the number of phases was 3 phases, and every is that 3 circle coils such as standard-sized sheet mouth series connection forms three symmetrical short pitch single layer winding by 6 coil Y=1-4 pitches, and wherein A is arranged in 1,4 mutually; 3,6; 9,12; 17,20; 23,26; Spider lable AX in 31,34 ten two grooves, B is arranged in groove 25,28 mutually; 27,30; 33,36; 5,8; 11,14; Spider lable BY in 19,22 ten two grooves, C is arranged in groove 13,16 mutually; 15,18; 21,24; 19,32; 35,2; Spider lable CZ in 7,10 ten two grooves; Three phase windings can be connected into Y, Δ.
Advantage of the present invention is: 1, three phase windings are the three-phase single layer structure of symmetry, copper factor height.Electromagnetic material utilance height, good economy performance.2, single layer winding has short pitch, the end is short, leakage reactance is little, few, the sinusoidal property of the harmonics of magnetic force content is good.3, this winding can be done the generator armature winding and also can do the motor winding, and Δ connects but can Y connect also, and harmonic ratio tradition range formula single layer winding reduces 68%, so the magnetic potential sine is good.
