ELECTRIC MOTOR DESIGN USING CAD TECHNIQUES SUPPORTED BY EXPERT SYSTEMS

Objective


The combination of computer aided design (CAD) techniques with various analysis subsystems supported by an expert system is quite a new concept in the field of electric motors. This project produced a final, tested prototype of an expert system for the design of electric motors and various analysis subsystems.
It is thought that the analysis subsystems, mechanical, thermal and electromagnetic, can be marketed indepently.
The positive results of this project came only after many technical problems developing the various analysis subsystems, then integrating them into an expert system. However, the potential for both analytic subsystems and expert systems for design on the European market is significant.
THE DESIGN OF ELECTRIC MOTORS HAS EVOLVED ALONG SEVERAL STAGES, SUPPORTED FIRST BY MANUAL CALCULATIONS AND THEN BY COMPUTER AIDED DESIGN (CAD) AND ANALYSIS (CAE) SYSTEMS.
HOWEVER, THESE SYSTEMS STILL REQUIRE THE SUPERVISION BY THE DESIGNER, WHO INTRODUCES ANY DECISION THAT LEADS TO THE PRODUCT. THEREFORE, THE MAIN PURPOSE OF THIS PROJECT IS TO CREATE AN AUTOMATIC AND INTELLIGENT SYSTEM FOR DESIGNING ELECTRIC MOTORS.

THIS IS TO BE ACHIEVED BY
1.- AUTOMATIC GENERATION OF THE MOTOR PRELIMINARY DESIGN FROM ITS SPECIFICATIONS. THE DESIGN METHODOLOGY IS TO BE BASED UPON ESTABLISHED WORKING PRINCIPLES FOR ELECTRIC MOTORS AND ON MANUFACTURER'S EXPERIENCE.
2.- DEVELOPMENT OF A MOTOR ANALYSIS SUBSYSTEM, THROUGH INTEGRATION OF ELECTROMAGNETIC, THERMAL AND MECHANICAL FINITE ELEMENT ANALYSIS.
3.- IMPROVEMENT OF THE DESIGN BY MEANS OF AN ITERATIVE PROCESS OF VALIDATION-REDESIGN VIA THE USE OF AN EXPERT SYSTEM.
4.- DEVELOPMENT OF A SUBSYSTEM FOR DOCUMENT GENERATION, NAMELY: BILL OF MATERIALS, MANUFACTURING DRAWINGS, WINDING DESCRIPTION AND MOTOR CHARACTERISTICS.
