Description
Technical field
The utility model provides a kind of Novel low noise oblique salient pole switched reluctance machines, belongs to switched reluctance machines field.
Background technology
Switched reluctance machines is a kind of novel buncher, and governing system has direct current concurrently, exchanges the advantage of two class governing systems, is the latest generation stepless time adjustment system of frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor of continuing.Its structure simple rigid, speed-regulating range width, speed adjusting performance is excellent, and all has greater efficiency in whole speed adjustable range, and system reliability is high.Mainly contain switched reluctance machines, power inverter, controller and position detector four part form.
Prior art problem is: one, and rotor, when rotating, when the position of the salient pole on it corresponding to the salient pole of on stator turns to the position corresponding to next salient pole, can form a larger torque ripple; Its two, due to pulsation, can in electric machine rotation, form larger vibration and noise; Its three, reduce reliability, make motor component occur fatigue damage, and bring environmental pollution.
Utility model content
The utility model object is to provide a kind of Novel low noise oblique salient pole switched reluctance machines, can reduce the noise and torque ripple that are formed in switched reluctance machines running, substantially can not increase motor manufacturing cost.
The oblique salient pole switched reluctance machines of Novel low noise described in the utility model, comprises rotor and stator, rotor and stator is equipped with salient pole, the salient pole of rotor is made up of oblique salient pole, oblique salient pole is linear pattern, and oblique salient pole tilts relative to the salient pole on stator, and the angle of inclination is 0 degree of-20 degree.
The oblique salient pole switched reluctance machines of described Novel low noise, if the salient pole on switched reluctance machines internal rotor is only made up of an oblique salient pole, the magnetic fields that coil in corresponding stator salient poles then on stator is formed on oblique salient pole after, can outside the acceleration of the forward produced, also can produce a negative torque simultaneously, negative torque can balance out the acceleration of part in the process of rotor accelerated motion, the corresponding salient pole of rotor is made to turn to the stator salient poles brief acceleration of coil electricity retarded, next stator salient poles coil electricity and when rotor is done work, linking that can be good, make its held stationary, eliminate the pulsation that rotor is formed in rotation process greatly, while pulsation reduces, when hot-wire coil because of stator salient poles switches, rotor rotates the steady of change, there is not the great variety of moment of torsion, so noise also can significantly reduce.The utility model does not need to increase any cost, only needs when producing rotor, the shape of salient pole on adjustment mould.Because the normal speed of switched reluctance machines is faster, then its frequency should be larger, torsion should be higher, so carrying out it reducing in the process of pulsation and noise reduction, larger negative torque should be needed to offset acceleration, to be effective, so the utility model speed is faster, the angle of the salient pole of oblique salient pole and stator is larger; Otherwise the utility model speed is slower, the angle of the salient pole of oblique salient pole and stator is less; According to suitable speed, the angle of the salient pole of the adjustment oblique salient pole of the utility model and stator, better can reduce pulsation, reduces noise.
The oblique salient pole switched reluctance machines of described Novel low noise, the length of two adjacent oblique salient poles is identical, but angle of inclination is contrary, and former and later two oblique salient pole tail prime ministers connect.Broken line type structure can effectively eliminate rotor axial power.
The oblique salient pole switched reluctance machines of described Novel low noise, the salient pole of rotor is broken line type salient pole.
The oblique salient pole switched reluctance machines of described Novel low noise, rotor with salient pole is " V " type salient pole.
The oblique salient pole switched reluctance machines of described Novel low noise, when switched reluctance machines because operating mode needs, when its rotor is shorter, the front and back tail prime minister that two incline directions are contrary connects length i.e. enough uses of oblique salient pole, constitute " V " type salient pole, when rotor is longer, when " V " type salient pole cannot reach the whole length of rotor, need to arrange multiple connected " V " type structure, and it is stable in order to ensure that switched reluctance machines torsion exports, need the various piece stress equalization ensureing salient pole on rotor, so corresponding shape " V " type structure can effectively ensure stability of the present utility model.
The utility model compared with prior art beneficial effect is:
The oblique salient pole switched reluctance machines of described Novel low noise, if the salient pole on switched reluctance machines internal rotor is only made up of an oblique salient pole, the magnetic fields that coil in corresponding stator salient poles then on stator is formed on oblique salient pole after, can outside the acceleration of the forward produced, also can produce a negative torque simultaneously, negative torque can balance out the acceleration of part in the process of rotor accelerated motion, the corresponding salient pole of rotor is made to turn to the stator salient poles brief acceleration of coil electricity retarded, next stator salient poles coil electricity and when rotor is done work, linking that can be good, make its held stationary, eliminate the pulsation that rotor is formed in rotation process greatly, while pulsation reduces, when hot-wire coil because of stator salient poles switches, rotor rotates the steady of change, the change of moment of torsion is little, so noise also can significantly reduce, and the utility model does not need to increase any cost, only need when producing rotor, the shape of salient pole on adjustment mould, because the normal speed of switched reluctance machines is faster, then its frequency should be larger, torsion should be higher, so in the process it being subtracted to pulsation and noise reduction, larger negative torque should be needed to offset acceleration, to be effective, so the utility model speed is faster, the angle of the salient pole of oblique salient pole and stator is larger, otherwise the utility model speed is slower, the angle of the salient pole of oblique salient pole and stator is less, according to suitable speed, the angle of the salient pole of the adjustment oblique salient pole of the utility model and stator, better can reduce pulsation, reduces noise.
The oblique salient pole switched reluctance machines of described Novel low noise, broken line type structure greatly reducing the part that rotor produces negative torque, while not affecting noise reduction, avoids the increase of negative torque, greatly reduces the loss of electric energy.
The oblique salient pole switched reluctance machines of described Novel low noise, when switched reluctance machines because scene needs, when its rotor is shorter, the front and back tail prime minister that two incline directions are contrary connects length i.e. enough uses of oblique salient pole, constitute " V " type salient pole, when rotor is longer, when " V " type salient pole cannot reach the whole length of rotor, need to arrange multiple connected " V " type structure, and it is stable in order to ensure that switched reluctance machines torsion exports, need the various piece stress equalization ensureing salient pole on rotor, so corresponding shape " V " type structure can effectively ensure stability of the present utility model.
