Design and implementation applying mechatronics system concept for a low-cost high performance wiring machine based on brushless DC motor drives

摘要

A wiring machine, driven by a brushless DC motor (BLDCM), is designed and implemented applying integration considerations of mechatronics system for a successful prototype development and described in this paper. Stable speed response during wiring operation with variations of load conditions could be achieved by making use of the portion shift of the overall system design efforts for this wiring machine. Features of its mechanical structure and mechanism of the developed wiring machine both can obviously lower the firmware requirements and level down sophisticated control algorithms, hence it is applicable to realize design concept and control methodology in two 8-bit data processing chips of PIC18F4431 and PIC18F8720. Description based on design issues of this wiring machine is also arranged for showing feasibility of the presented concept and its realization approach herein. Meanwhile, it demonstrates the effectiveness of the proposed simple control strategy for the low-cost high performance wiring machine system.
