Abstract

Line motors are playing a more and more important role in all kinds of trade, especially in machine tool feed system. We carry out our study in motor , software and hardware servo system based on flat AC permanent magnet synchronous linear motor(PMSLM).

First introduce the design method of armature ,core of al and magnet which can minish the thrust ripples, then introduce the means of assembly base on high thrust permanent magnet synchronous motors.

To ensure the accuracy to a high requirements and get a wide speed range, we choose the dsp of Texas Instruments named TMS320F2812 which is the core of the servo system .In the paper we set up mathematical model of PMSLM, then analyse the current control strategies and choose the vector control method which is realized by the method of

id?0.The three phase sine wave is compounded by space

voltage pulse width modulation(SVPWM).The arithmetic realized by C language and assembly language in DSP. Intelligent Power Model (IPM) is the core of the power amplification circuit system which also contains current sampling circuit, photoelectric-isolation circuits, over-voltage protection circuits, under-voltage protection circuits and power supply.

As a result of the knowledge and ability limit, this topic only does a fundamental research to the linear motor.

Key words: permanent magnet synchronous linear motor(PMSLM), DSP, SVPWM, vector control
