Abstract:Aiming at the speed regulation problems of the constant torque load such as adjustable speed asynchronous magnetic coupling (ASAMC) matching belt conveyors, based on the analysis of the magnetic field characteristics of the coupling, its slip speed-air gap-torque equation is obtained, which matches the load start characteristics. The variation of the acceleration under the matching condition of the air gap at the start of the belt conveyor is quantified. On this basis, a soft start control strategy for the matching of ASAMC and the belt conveyor is established. A 125 kW ASAMC experimental platform was set up and experiments were conducted. The experimental results and field applications verified the reliability of the algorithm.
