Description
Technical field
The invention belongs to machine field, particularly as being a kind of switched reluctance motor of new structure.
Background technology
Switch magnetic-resistance motor system（Switched Reluctance Drive ：SRD）It is the latest generation continuous speed regulation system grown up after frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor, is the light, mechanical, electrical integrated new and high technology for integrating modern microelectronic technology, digital technology, Power Electronic Technique, infrared electro technology and modern electromagnetic, design and manufacturing technology.
SRD is main by switched reluctance motor（SRM）, power inverter, controller, the most of composition of rotor position detector four.Comprising control circuit and power inverter in controller, and rotor position detector is then installed in one end of motor.
Switched reluctance motor used by SRD（SRM）It is the part that energy converting between mechanical is realized in SRD, is also the outstanding feature that SRD is different from other electric motor drive systems.Existing SRM systems double-salient-pole variable reluctance motor, the salient pole of its stator and rotor is overrided to form by common silicon steel sheet.Rotor both without winding or without permanent magnet, was wound with concentratred winding in stator poles, two windings diametrically are linked up, referred to as " phase ", and SR motor can be designed to various different phase table structures, and the number of poles of stator and rotor has various different collocation.The number of phases is more, step angle is small, advantageously reduces torque pulsation, but complex structure, and main switching device is more, high cost, now using it is more be four phases（8/6）Structure and three-phase（12/8）Structure.
Switched reluctance motor transmission system combines the advantage of Induction motor drives and direct current drive electric motor of automobile transmission system, is the contenders of these transmission systems, and its major advantage is as follows：
1st, switched reluctance motor has larger utilization factor of motor, can be 1.2~1.4 times of induction conductivity usage factor.2nd, the simple structure of motor, does not have any type of winding on rotor；There was only simple concentratred winding on stator, end is shorter, does not have alternate jumper.Therefore, with manufacturing process is few, low cost, reliable operation, a little repair the features such as.3rd, the torque of switched reluctance motor is unrelated with current polarity, only need to unidirectional current excitation, ideally in common ratio translation circuit per mutually can only with a switch element, and with motor windings in series, will not there is the straight-through danger of two switch elements as PWM inverter power supply.So, Switch reluctance motor driving system SED circuits are simple, and reliability is high, and cost is less than PWM Alternating Current Governor Systems.4th, the structure type of switched reluctance motor rotor limits small to rotating speed, can be made into pot-motor, and the rotary inertia of rotor is small, can at any time change the size and Orientation of phase circle torque again in each commutation of electric current, thus system has good dynamic response.5th, the control that SRD systems can be by the conducting to electric current, disconnection and to amplitude, is met the mechanical property of different loads requirement, it is easy to accomplish the function such as soft start and four quadrant running of system, and control is flexible.Again because SRD systems are self-synchronizing system operations, will not occur unstable and oscillation problem in low frequency as the induction conductivity of conversion power supply.6th, because SR switched reluctance motors employ the structure and method for designing of uniqueness and control skill accordingly, its processed in units can compare favourably with induction conductivity, or even also hold advantage slightly.The efficiency and power density of SRD systems can maintain teaching level in broad speed and loading range.
The major defect of Switch reluctance motor driving system is：
1st, there is torque pulsation.Knowable to operation principle, the torque produced on S switched reluctance motor rotors is formed by stacking by some row pulse torques, due to the influence of double-salient-pole structure and magnetic circuit saturation nonlinearity, synthesis torque is not a constant torque, and having certain harmonic component, this have impact on SR motor low cruise performances.2nd, the noise of SR motor transmission agents is bigger than general motor with vibrations.
Disadvantages mentioned above, is substantially that the structure of the Switch reluctance motor driving system i.e. switched reluctance motor SRM of SRD systems is caused, and wants to reduce torque pulsation and its noise that causes and vibrations it is necessary to change the structure of switched reluctance motor SRM.
The content of the invention

Specific embodiment
Embodiment 1：Fig. 1 is outer single-screw tooth switched reluctance machines 011 extremely arranged in a straight line, outer single spiral coil 0212 is arranged outside outer single-screw iron core 0211 constitute outer single-screw stator tooth pole component 0219, two outer single-screw stator tooth pole components 0219 outer single-screw tooth stator 021 extremely arranged in a straight line of composition arranged in a straight line vertically, mover tooth pole 031 is arranged in it, along rotation direction of principal axis conveyor screw, pitch is two length of outer single-screw stator tooth pole to mover tooth extremely semicircular ring.
The pitch of spiral iron core 0211 is 1000mm, length is that 460mm inner sides form spiral circle cambered surface, for coordinating with mover, form the magnetic loop of rotation direction of principal axis, the yoke portion of spiral iron core 0211 is the yoke 0213 with two global formations of spiral iron core 0211, if the material of spiral iron core 0211 is silicon steel sheet, it is with the integrally formed spiral iron core 0211 of yoke 0213, with the integrally formed spiral silicon steel sheet of yoke 0213, along the circumferential direction build up one-piece auger monodentate pole iron core 0211 and yoke 0213, it is not shown in figure, the pitch of mover tooth pole is 1000mm, length is 1000mm, be exactly two length be 500mm single-screw tooth pole unit helical arrangement together, it is placed in single-screw tooth stator extremely arranged in a straight line.Because component stator arranged in a straight line in single-screw tooth pole is being two-layer, when ground floor stator tooth pole center line overlaps with corresponding mover tooth pole unit center line, second layer stator tooth pole center line its be in opposite location, so due to rotator inertia in rotation process, mover continues rotation makes another single-screw tooth extremely produce magnetic pull to single-screw tooth pole helical arrangement mover, rotate the mover, it is reciprocal with this, the mover is set persistently to rotate, after stopping operating, the permanent magnet for being positioned away from stator tooth pole position attracts the mover, make its center line with corresponding stator tooth pole center deviation, stator tooth pole rotates mover tooth pole when enabling to enable.
A kind of switched reluctance motor, including stator tooth pole and mover tooth pole, mover tooth pole are rotatably assorted relative to stator tooth pole, and the number of the stator tooth pole is equal with the number of mover tooth pole；Along rotating shaft direction for stratiform is fixedly connected, the thickness range of stator tooth pole thickness correspondence mover tooth pole is referred to as mover tooth pole unit for stator tooth pole（Stator tooth pole, refers to single stator tooth pole；Stator tooth pole thickness is stator tooth pole iron core thickness plus the stator tooth pole coil thickness being arranged outside it；Other mover can be integral forming structure, it is integrated connection, or layered arrangement between every layer, stacking is fixedly connected between every layer, so the thickness range of stator tooth pole thickness correspondence mover tooth pole is referred to as mover tooth extremely unit, mover tooth pole unit includes at least one mover tooth pole）The stator tooth polar curve circle that stator tooth pole is arranged by stator tooth pole iron core and its outside is constituted, the end group that stator tooth pole iron core forms air gap with mover tooth pole is the arc surface of male-female engagement, stator tooth pole is with the matching relationship of mover tooth pole, no matter mover tooth pole rotates to any angle relative to stator tooth pole, at least one of which stator tooth pole center line forms angle α with the mover tooth pole center line of corresponding mover tooth pole unit, 0 ＜ α≤β, β are the angle of stator tooth pole iron core or mover tooth pole along the circular arc correspondence center of circle of the cross section of rotation direction of principal axis.
It is poor that mover tooth polar circle arc angle and stator tooth pole iron core arc angle differ only by the arc angle that air gap therebetween causes, due to air gap very little, the two arc radius difference also very little, the corresponding arc chord angle difference of identical Tooth width also very little, assuming that air gap is infinitely small, then the corresponding angle of concavo-convex arc surface is just equal, so β is to represent stator tooth pole iron core arc chord angle, mover tooth polar circle arc angle is represented again, and stator tooth pole iron core arc chord angle is also referred to as stator tooth polar circle arc angle.
