Research on Rope-Less Hoist System Driven by PMLSM
Rope-less hoist system driven by permanent magnet linear synchronous motor has the advantages of simple structure, small volume, high force, unlimited hoisting height and speed. So, it is attracting more attention, increasingly becoming a research hot and difficult in the vertical hoist field. In this paper, a design scheme of direct driving high-speed elevator is proposed according to the key technical problems of rope-less hoist system driven by PMLSM, and then a small-sized home elevator prototype is built. Experimental results show the safe and stable operation performance of the experimental device, which offers the reference for the further research and the development and application of PMLSM rope-less hoist system.
