Abstract
This invention relates to a three-phase ac electric motor, particularly for double three-phase permanent-magnet synchromotor, and its winding. This invention double three phase permanent-magnet synchromotor is composed of: a stator, a rotor and accessories. On the stator, two windings are placed with an electric angle. This invention can eliminate sequence 5, sequence 7 harmonic wave obviously, lower temp.-rise and noise, lower loss, increase electric motor efficiency. This invention motor combined with fequency-transformer can be used for electric automobile, electricity propulsion ship and others.
Description
Invention field
The present invention relates to three phase alternating current motor, more particularly, relate to the coil windings of three-phase permanent magnet synchronous motor.
Background technology
During the work of public three-phase permanent magnet synchronous motor, there is the 6K+1 subharmonic in magnetic potential of air gap, and especially 5 times, 7 subharmonic are comparatively serious, and the harmonic wave that magnetic potential of air gap exists has had a strong impact on the raising of three-phase permanent magnet synchronous motor performance.In order to reduce or the harmonic wave of the three-phase permanent magnet synchronous motor performance of eliminating the effects of the act, existing technical scheme is to take some measures on motor material and manufacturing process, but DeGrain.
Summary of the invention
The purpose of this invention is to provide a kind of double three-phase permanent-magnetic synchronous machine, the harmonic wave that it has eliminated the some effects motor performances has obviously improved efficiency of motor.
The object of the present invention is achieved like this: a kind of double three-phase permanent-magnetic synchronous machine is made of rotor, stator and annex, and stator is provided with the winding of the electrical degree that staggers on the 2 cover spaces.
Stagger on the spaces windings of electrical degree of 2 covers constitute the phase difference winding, 2 cover windings connect respectively 2 groups time phase different three-phase alternating-current supplies.The rotating magnetic field direction that is produced during 2 cover winding work is identical; 5 times of the time being produced of two cover windings work, 7 subharmonic directions are opposite.
On the basis of technique scheme, the present invention also has following further scheme:
Variable-frequency governor is set on motor.
Advantage of the present invention is as follows:
Because the present invention uses the phase difference winding, and 2 in phase difference winding cover winding connect respectively 2 time phase different power supplys.So the fractional harmonic that is produced during the work of phase difference winding can be cancelled out each other.The present invention has tangible elimination effect to 5 subharmonic, 7 subharmonic, effectively reduces electric machine temperature rise and noise of motor, has reduced supplementary load loss, has improved electric efficiency.
After being provided with variable-frequency governor on the motor, not only increased the function of motor, and also relative compact of the structure of motor.
Description of drawings
Fig. 1 is a structural representation of the present invention.Among the figure: the 1-A winding; The 2-B winding; 3-space electrical degree.
Embodiment
A kind of double three-phase permanent-magnetic synchronous machine, rotor, stator, annex are identical with common alternating current machine, be a cover winding on the stator of common three phase alternating current motor, and winding are connected with one group of three phase mains.The notion of " two three-phase " is 2 cover windings, and 2 cover windings connect corresponding three-phase alternating-current supply respectively.2 cover windings of present embodiment are A winding (1) and B winding (2).A winding (1) is identical with B winding (2) structure, and 30 degree space electrical degrees (3) just stagger.Be noted that A winding (1) and B winding (2) the just embodiment of 30 degree space electrical degrees (3) that staggers, in case of necessity other angle can also be arranged.A winding (1) is connected the three-phase alternating-current supply that two groups of time phase differences 30 are spent (the space electrical degree of corresponding winding) respectively with B winding (2).
The three-phase alternating-current supply of two groups of time phase difference 30 degree can produce by frequency converter, also can produce by phase shifter.
Stagger one of ways of 30 degree space electrical degrees (3) of A winding (1) and B winding (2) are to split winding.Such as, stator (4 utmost points, 48 grooves) is gone up every utmost point phase winding be split as A winding (1) and B winding (2), arranging is A winding (1) the preceding, after being arranged in is B winding (2).
A kind of double three-phase permanent-magnetic synchronous machine that the present invention proposes is not limited to " two three-phase ", can also be many three-phases in order to eliminate more harmful harmonic wave.Such as, also every phase winding (phase winding of common three phase electric machine) can be split as A, B, C...... winding.Realize many used power supplys of three phase times, the space electrical degree that the time phase difference angle equals to stagger between winding.
In sum, " two three-phase " notion of the present invention's proposition comprises many three-phase structures.
In order to strengthen function of the present invention, the terminal box of motor is amplified, and variable-frequency governor is installed in terminal box.Frequency conversion transfers device also can be installed in other position of motor.Such as, at the blower fan case of motor afterbody the radiator mount pad being set, frequency conversion transfers the heating part in the device to be installed on the mount pad of blower fan case.For better radiating effect is arranged, radiator mount pad and blower fan case should be used aluminum alloy materials.
In order to simplify the supply power mode of motor, be provided with phase shifter between A winding (1) and the B winding (2).Execution mode is that the input of three terminals of A winding (1) as three phase mains, three terminals that B winding (2) connects power supply are attempted by on three terminals of A winding (1) by phase shifter.After the present invention installs phase shifter, only need the frequency converter motor of general function just can normally move.
