Abstract
The utility model relates to an equal turn type single-phase winding of an intermediate frequency permanent-magnet electric generator. The single-phase winding is characterized in that when being provided with 36 grooves and 14 poles, the single-phase winding is formed by connecting 12 equal turn coils in series, the coil pitch is in two types, 8 coils have the pitch Y of 1-3, and 4 coils have the pitch Y of 1-2; when being provided with 36 grooves and 10 poles, the single-phase winding is also formed by connecting 12 equal turn coils in series, but the coil pitch is in only one type, namely, Y is equal to 1-4. The equal turn type single-phase winding has the advantages that in a multipolar permanent magnet single-phase electric generator, the difficulty of arrangement in traditional concentric and equal turn form when the pole number is large and the groove number is small is solved, the single-phase winding is formed with the form of unequal or equal space and equal turn, thereby the aim of small harmonic wave of the magnetic potential of a concentric unequal turn single-phase winding can be achieved, the processing is simpler, and the implementation is more convenient.
Description
Technical field
The utility model relates to a kind of intermediate frequency permanent magnet AC motor winding, relates in particular to the single-phase winding of a kind of intermediate frequency permanent magnet generator equal-turn type.
Background technology
The intermediate frequency magneto has become the developing direction of energy-saving electric machine, and the groove number is few but the general number of poles of intermediate frequency magneto is many, and therefore the single-phase winding of this motor can't not wait circle concentric type structural configuration by the traditional single phase winding, can only be by general equal-turn type structural configuration.But this layout motor windings the harmonics of magnetic force content is many, and for example noise is big, efficient is low for the performance of monophase machine, voltage-form distortion rate is big, often can not reach the requirement of technical standard.Seek a kind of circle winding that waits, make that technology is simple, it is convenient to implement and harmonic content in its motor windings magnetic potential is few, make voltage-form distortion rate little, noise is little, the efficient height, this has actual realistic meaning to the new product development that promotes the intermediate frequency permanent-magnet single-phase generator.
Summary of the invention
The purpose of this utility model provides the single-phase winding of a kind of intermediate frequency permanent magnet generator equal-turn type, reaches the purpose that reduces the harmonics of magnetic force.
The utility model is achieved like this is characterized in that working as winding is several 36 grooves of groove, and when number of poles was 14 utmost points, the number of phases was single-phase, 12 of the winding wire number of turns, and wherein the coil number of pitch Y=1-3 has 8, and the coil of pitch Y=1-2 has 4.Under 8 coils of pitch Y=1-3 at groove 2,4; 7,9; 12,14; 15,17; 25,27; 30,32; In 35,1 ten six grooves, under 4 coils of pitch Y=1-2 at groove 18,19; 23,24; 28,29; In 33,34 eight grooves, all coils number of turn equates that all whole 12 coils are connected into single-phase winding.
Another implementation method of the present utility model is, it is characterized in that when winding be several 36 grooves of groove, during number of poles 10 utmost points, the number of phases is single-phase, 12 of the winding wire number of turns, each coil span all are Y=1-4, the number of turn of each coil all equates, under 12 coils 1,2,3,4,5,6; 9,10,12,13; 16,17,19,20; 23,24,26,27; 30,31,32,33,34,35 in totally 24 grooves, all are connected into single-phase winding.
The utility model has the advantages that: in multipole permanent-magnet single-phase generator, overcome because of number of poles multiple-grooved number and can't make the difficulty of single-phase winding after a little while by traditional concentric type unequal-turn arranged in form, and with equidistant or equidistant but etc. the form of circle constitute single-phase winding, this single-phase winding the harmonics of magnetic force is little, can reach the single-phase positive chorded winding performance level that traditional concentric type unequal-turn is arranged, technology is simpler, enforcement is more convenient.
