A CONTROLLABLE and ADJUSTABLE PERMANENT MAGNETIC LEVITATION SYSTEM

摘要

A brief introduction of various maglev types for linear motor driving train is presented in this paper, and a new control lable and adjustable parma-nent magnetie levitation system is emphatically intmduced. In fact, it is a mixed system of electromagnet and permanent magnet. In the system, the permanent magnet contributes the main levita-tion force and the electromagnet does the controlled force. Such a system levitating a 35Kg load has been built in our lab. Its possibility and advantages have been proved.
