Description
Technical field
The present invention relates to a kind of switched reluctance machines, refer in particular to a kind of switched reluctance machines containing multiple distributed multi-drive.
Background technology
Along with the aggravation of current oil shortage of resources and environmental pollution, the development of electric automobile is subject to people's attention day by day.Electric automobile has the characteristic of high efficiency, low emission.Secondly the torque response of electric automobile rapidly, accelerate fast, motor can decentralized configuration easily as realized four motorized wheels and four-wheel steering, it can also realize regenerative braking and energy regenerating, improves the safety and reliability of electric vehicle brake.
At present, have a lot as the drive system of electric automobile and motor, Switched Reluctance Motor is because its structure is simple, whole system has the features such as efficiency is high, controllable parameter is many, starting current is little, starting torque is large, is one of extremely potential drive system of electric motor vehicle.
Whole Switched Reluctance Motor comprises switched reluctance machines, power inverter, position transducer, controller four part of double-salient-pole, be a kind of novel speed change dragging system, its speed adjusting performance has asynchronous motor frequency-changing speed-regulating and the wide advantage of DC motor speed regulating concurrently.
Although Switched Reluctance Motor has good speed adjusting performance, also there is many problems.With regard to current development level, the major defect that switched reluctance machines exists has: 1, torque pulsation is comparatively large, and the noise problem caused by torque pulsation is comparatively outstanding; 2, system reliability is still not high.Although used switched reluctance machines is respectively on good terms and is worked alone, reliability and safety comparatively common asynchronous moter increases, real once phase-deficient operation, noise then can be caused to surge, torque and rotating speed can sharply decline, and even export without torque, cause whole system to run.
Summary of the invention
The object of the present invention is to provide a kind of torque pulsation little, noise is little, substantially increases the switched reluctance machines of the safety and stability of battery.
The technical solution used in the present invention is: a kind of switched reluctance machines of distributed multi-drive, comprise controller, switched reluctance machines and position detector, it is characterized in that: the stator of described switched reluctance machines contain 2 to or 2 to above magnetoresistive cell diametrically, each magnetoresistive cell and its magnetoresistive cell diametrically form a driver element, each driver element is controlled by different controllers respectively, by different battery-powered, wherein magnetoresistive cell is made up of adjacent not homophase magnetic pole and winding.
Described stator, rotor are along the stator, the rotor core that electrical axis length direction comprise more than 2 or 2.
The stator of the present invention's phase wherein also adds auxiliary winding, and auxiliary winding two ends connect civil power by charge power module.
The present invention utilizes the double-salient-pole multipolar system structure of Stators for Switched Reluctance Motors iron core, utilize the method for axial cutting and radial cutting, by increasing the number of poles of stator, rotor silicon steel sheet, and to length direction, the way of multiple stator core is installed at motor shaft, with the number of the number of magnetic poles and driver element that increase motor.By the magnetoresistive cell of multiple control gas drive circumferencial direction 180 symmetry, each magnetoresistive cell and its magnetoresistive cell diametrically form a driver element, each driver element often both can work independently, also can multiple unit work simultaneously, realize driving the multi-cylinder of electric motor car, which greatly enhances the reliability of SRD.Simultaneously because of the battery pack that each driver element is corresponding different, like this battery pack of motor is broken the whole up into parts, avoid the group effect of battery, substantially increase the safety and stability of battery pack.
In addition, because electric automobile will be set out on a journey, the problem of charging, accumulate must first be solved.Owing to needing instantaneous powerful power power to electric vehicle rapid charging, normal grid facility cannot meet, and must use special charging station, charging pile.And electric automobile charging station net is difficult to short-term construction, main cause to build special charging network, costly, non-ly overnight can realize.Therefore conveniently can not charge, also become electric automobile and enter into other a great problem of common people.The present invention except concentratred winding is housed, is also equipped with auxiliary winding on every phase stator.Auxiliary winding two ends are by charge power module configuration line voltage.Closed by the lotus root of stator concentratred winding and auxiliary winding, produce the function being equivalent to transformer, thus solve the problem of electric motor car charging, do not need to use special charging pile, only need access common domestic power grid just can to vehicle charging.
the present inventionby using above technical scheme, following beneficial effect can be reached:
1. every two magnetoresistive cell diametrically of switched reluctance machines of the present invention form a driver element, and each driver element is controlled by different controllers respectively.Separate work, can realize driving the multi-cylinder of electric motor car.When a unit breaks down, only need stop this cell operation, motor, except gross output declines to some extent, there is no other impact, which greatly enhances the reliability of SRD.And common switched reluctance machines, when one breaks down or phase-deficient operation mutually, then noise can be caused to surge, torque and rotating speed can sharply decline, and even export without torque, cause whole system to run.
2. because the stator of switched reluctance machines, rotor are double-salient-pole multi-polar structure, and a motor can install multiple stator and rotor iron core, can increase the number of magnet poles of motor stator rotor core so easily, utilizes the work of multiple unit drive motors.By changing the work schedule of different driving unit, make different driving unit Driving Torque size complementary thus the torque pulsation of motor is reduced, running noise reduces.The battery pack of electric motor car is divided into multiple unit simultaneously, effectively avoids group effect, greatly improve the safety and stability of battery pack.Do not affecting under power of motor density case, under motor can be operated in safe voltage, even if there is fortuitous event, also can guarantee the safety of passenger.
3. because the stator of switched reluctance machines is except being equipped with concentratred winding, wherein a phase is also equipped with auxiliary winding, and auxiliary winding is powered by charge power module, and module input is civil power.During charging after module access civil power, closed by the lotus root of concentratred winding and auxiliary winding, produce the function of transformer, thus do not need the special charging of charging pile realization to electric motor car, solve the problem that electric motor car charging is difficult well.
