The first control strategy has the disadvantages such as a large amount of computations, inherent pull-out torque, difficulties in realizing the adaptive control and so forth. For the rotor flux-oriented control, changing of load or the rotor speed will result in increased or decreased torque winding currents, which will change the magnetic field distribution in the air gap. Assumption that magnetic field is approximately equal to that generated by torque windings will affect the levitation performances.

分析表明：气隙磁场定向控制中存在最大转矩限制、非线性机械特性，难以实现自适应控制等问题；对转子磁场定向控制而言，当负载或转速变化时，由于转矩控制绕组转矩电流变化将导致气隙磁场发生改变，如果仍以转子磁场近似替代气隙磁场作为悬浮依据，必然影响到悬浮控制性能。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。
