Study On Accquisition For Fault Symptoms Of Permanent Magnet Linear Synchronous Motor Vertical Transportation System

Permanent magnet linear synchronous motor and servo system with high efficiency, energy-saving and other significant advantages, it has made a successful development and application in our country ,and gets more and more attention. the"sectional permanent magnet linear motor drive for mine transportation system"is a new research project, so many issues is still to be resolved, in which the operation stability is the key issues. Some signs will be shown before failure of the motor, its direct and indirect parameters would have some tendency, we can restrain failures by parameters detecting.In this paper, sub-type permanent magnet linear motor lift system as the research object, through analysis of its structure and operation principle, researching these parameters'changes when the system occurs failures.Based on the TMS320F2812 and sensor technology established the test monitoring system. The system not only can complete the on-site real-time monitoring, but also complete a continuous parameter analysis.The system is constituted by Hardware and software. Hardware is composed by voltage, current, air gap, speed, insulation modules, without position sensor power angle detection module, analog signal conditioning circuits, A/D conversion circuit, the switch volume acquisition module, communication module. Software design includes data acquisition, SCI initialization, monitoring program design. Experimental results show that this design can meet the practical requirements; less error can be applied to practical applications. The monitoring system for the future development of more large-scale management system has taken the foundation and ground-breaking step, the results have advanced and the potential economic benefits.Experimental results show that this design can meet the practical requirements, less errors, it can be applied to practical applications.
