Auto-discharging system for jigging machine based on SRM

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.
