Research About Optimization Method Of Motor Parameter High Frequence Electro-spindle

High frequence electro-spindle is the core component of high frequence MC.It functions as lathe spindle also as motor spindle.It avoids complicated transmission eqippment and has such advantages as wide range of speed modulation,low vibration , quick start and nicety stop.It improved production efficiency and manufacturing quality greatly.This technology is the focus and hot point of technology competition across the world.Stator and rotor of high speed motor is the key component of high frequence electro-spindle. The design method of high frequence electro-spindle was introduced referring to aynchronous motor design theory because there exits no systematic design theory on it in China presently.Of course the speciality of its structure and elelectromagnet was considered.Based on this design treory,a programme of designing high frequence eletro-spindle was realized with the computer language of matlab.An actual example was taken to prove this method.This example is a product of Ibag corporation of Switzerland with the type of HF230.4A20 CFHKP.Then take a comparision between computional parameter and actual product parameter.On the basis of designing method, optimization model was completely built inclding design parameter,target function and constraint condition. The target function was power density of motor.Then its optimization result was presented by means of genetic algorithm because of some discrete parameter , complicated target function and inequation constraint.This algorithm can be contained in matlab,which was downloaded from internet at web site www.fecitcom.cn. If the optimization model was built,the result will be gained easily using GA toolbox.To get a wider range of frequence modulation,driving technology of high frequence electro-spindle uses vector control.This paper has built simulation model of vector control system based on software of Madab/sirnulink After setting inner parameter of it,we can see the simulation plot and understand thatthe technology index of high speed motor designed is right.
