Abstract
This invention provides a SRM which can increase the efficiencies of motor and torque, reduce vibrations/noises and make the winding operations easily. The said SRM is composed of pole projections and retention structures among poles of stators-rotors, phase coils winded on each pole of the stator and secondary coil winded on each pole of the stator connected with each other.
Description
Technical field
The present invention relates to motor, particularly relate to switch-type magnetic resistance motor (Switched ReluctanceMotor:SRM).
Background technology
In general, that SRM can divide into is single-phase, two-phase, three equates, be by the rotor-position sensor of a drive circuit that drives described SRM, detection rotor position and according to the control assembly of the described drive circuit of control of this position of stator transducer output with by stator and rotor and be used to form stator system structure that phase coil mutually constitutes and link mutually and constitute.
Be added in the structural mode of such stator system with the instantaneous voltage of rectangular pulse and drive SRM, exist variation to make vibration and noise increase such problem owing to the instantaneous electric power that causes in the stator system structure the direct current form.For by absorbing the instantaneous electric power variation of such stator system structure, address the above problem for the scheme of the stator phase coil of connecting, and constitute the SRM that except that phase coil, also appends ancillary coil energy delivery.
Like this, the SRM relevant with the prior art of having appended ancillary coil as shown in Figure 1, in order to drive SRM11, and the drive circuit 12 that the switching device of IGBT (insulated gate bipolar transistor) etc. is constituted, be used to detect the rotor-position sensor 13 of SRM rotor-position and link formation according to the control assembly 14 that described drive circuit 12 is controlled in the output of rotor-position sensor 14.
Only show the drive circuit in 3 the situations of a phase in mutually of SRM among Fig. 1.
And, appended ancillary coil the SRM coil form as shown in Figure 2, phase coil 23 is concentrated on each magnetic pole in 6 magnetic poles of stator 21, on ancillary coil 24 two groups of (every group each 3) magnetic poles in 6 magnetic poles that spread all over stator 21.Thereby the magnetic pole that is wound the line together by phase coil 23 and ancillary coil 24 is many because of its coil amount, and compares with other magnetic pole, has just become to have the asymmetric structure of subsideing.
Also there is following problem in the SRM relevant with above-mentioned prior art:
At first, because the winding mode of phase coil and ancillary coil is different, and make the winding operation difficulty.
Secondly, owing to have dissymmetrical structure because of ancillary coil makes magnetic pole, and produced weak position, magnetic field, thus make the decreased performance of efficient, torque and the reduction vibration/noise of motor.
The 3rd, owing to compare with phase coil, (End-Turn) is elongated for the bond terminal of ancillary coil, has increased coil resistance, and institute is so that the efficient reduction of motor.
Summary of the invention
Therefore, in order to solve the problem of above-mentioned prior art, the purpose of this invention is to provide and carry out winding operation easily and improve moyor and the SRM of the property of torque and reduction vibration/noise.
The SRM relevant with for achieving the above object the present invention is characterised in that and comprises: pole parts outstanding and have between each magnetic pole the stator of subsideing structure, rotor, respectively the phase coil on each magnetic pole of stator, respectively on each magnetic pole of stator and interconnective ancillary coil.
SRM related to the present invention has following effect:
At first, because for all magnetic poles of stator, phase coil and ancillary coil wind the line equably, whole magnetic poles are become have symmetrical structure, can be prevented the reducing of moyor and torque, prevent to vibrate/effects such as increase of noise.
Secondly, twine because each magnetic pole of ancillary coil relative stator is concentrated, and end winding is shortened, wire resistor reduces, and thus, can prevent that moyor from descending.
The 3rd, because the coiling homomorphosis of ancillary coil and phase coil, and make the winding operation transfiguration easy, can make make efficiency improve.

Specifically execute mode
Below, with reference to accompanying drawing, describe the better embodiment of SRM related to the present invention in detail.
Fig. 3 is the figure that is used to illustrate according to SRM coil form of the present invention, Fig. 4 be expression according to the inductance of SRM of the present invention and the curve of torque characteristics, Fig. 5 is the curve of expressing according to the induced voltage of the ancillary coil of SRM of the present invention.
SRM related to the present invention, as shown in Figure 3, at first, phase coil 33 is kept the form on each magnetic pole of concentrating 6 magnetic poles that are wrapped in stator 31.And ancillary coil 34 is different with prior art, same with phase coil 33, each magnetic pole in 6 magnetic poles of stator 31 is concentrated coiling, but make the ancillary coil 34 of every group of 3 magnetic poles of two opposite groups in 6 magnetic poles connection this point of contact respectively different with phase coil 33.
Like this, because SRM related to the present invention is in the effect that keeps ancillary coil in the past, 6 magnetic poles of 34 pairs of stators 31 of ancillary coil are concentrated coiling, so all magnetic poles are symmetry all, and identical sectional area is arranged, the end circle shortens equally with phase coil 33, thus, can solve the structure problem of ancillary coil in the past.
Fig. 4 shows inductance and the torque characteristics of SRM related to the present invention, and the inductance that shows phase coil 33 changes La, Lb, the Lc along with phase place resembles, ancillary coil 34 inductance own resemble the characteristic that changes the Lf.
At this moment, the induced voltage that causes in ancillary coil 34 because the voltage and current of phase coil 33 changes as shown in Figure 5.
Therefore can think: resembled by the inductance of ancillary coil 34 of the inductance variable effect of phase coil 33 and change Maf, Mbf, the Mcf, chain effect along with phase coil 33 and ancillary coil 34, the electric current of ancillary coil 34 (If) is certain and phase change is irrelevant, and whole torque (T) also is constant.
Here, torque (T) produces with the electric current and the variation inductance of phase coil 33 and ancillary coil 34.
The result, SRM related to the present invention, the coil form by changing ancillary coil and the structure of magnetic pole, and can be desirably in when solving existing problem can also keep and the effect (promptly reducing the effect of the vibration/noise of SRM) of the same or better ancillary coil always.
And have following effect at the relevant SRM of the present invention described above:
At first, owing to all magnetic poles for stator, phase coil and ancillary coil wind the line equably, make All magnetic poles become and have symmetrical structure, can be prevented reducing, preventing of moyor and torque The increase texts of vibration/noise.
Secondly, twine because each magnetic pole of ancillary coil relative stator is concentrated, and end-coil shortened, Wire resistor reduces, and thus, can prevent that moyor from descending.
The 3rd, because the coiling homomorphosis of ancillary coil and phase coil, and make the winding operation transfiguration easy, Make efficiency is improved.
