翻译部分英文原文Auto-discharging System for Jigging Machine Based on SRMAbstract-This paper introduces an auto-discharging system for jigging machine based on switched reluctance motor (SRM). In this system, SRM is used to replace the traditional asynchronous motor. The hardware system, controller and software design methods are discussed in this paper. AT89C51 is taken as the core component of the speed regulation controller for SMR and works with other peripheral circuits to realize effective control on motor. The experiment shows that auto-discharging system for jigging machine based on SRM is feasible and can play an important role in stabilizing clean coal ash content, reducing clean coal loss, improving product quality and separation efficiency.Keywords：Jigging machine, auto-discharge system; switched reluctance motor1. INTRODUCTIONThe jigging machine is a kind of mechanical mineral sorting equipment and occupies an important position in the production of the large modem coal preparation plant. However, the automation level of jigging machine has been out-dated. The backward control mode in jigging coal preparation restricts the product quality, separation efficiency and process ability. One of the reasons is the lower efficiency of the motor which is used commonly in discharging system for jigging machine. How to improve the efficiency of motor has an important significance for improving coal preparation efficiency and stabilizing product quality.　　Switched reluctance motor (SRM) with better start characteristics is suitable for starting frequently in adverse environmental condition, high temperature and even strongvibration conditions and keeps higher efficiency. Based on these characteristics, we use switched reluctance motor instead of the traditional asynchronous motor to developauto-discharging system for jigging machine based on SRM. The experiment shows that auto-discharging system for jigging machine based on SRM is feasible and can play an important role
