LINEAR PERMANENT MAGNET DRVING SYSTEM AND PERMANENT MAGNET DRIVING AND MAGNETIC SUSPENSION ROADWAY SYSTEM

摘要

The invention relates to a linear permanent magnet driving system and a permanent magnet driving maglev train rail system, the linear permanent magnet driving system comprises spiral rotors and stators, wherein at least one of the spiral rotor and the stator adopts the structure having a permanent magnet while the other one adopts the structure having the permanent magnet or a magnetizer; when the spiral rotors are driven by an engine to rotate, linear motion of the spiral rotors is achieved by means of the magnetic force between both, and speed of the linear motion of the spiral rotors can reach supersonic speed at most. By applying the linear permanent magnet driving system to the permanent magnet driving maglev train rail system, the entire rail can avoid the use of both permanent magnet and driving coil, and the construction cost of maglev train rail is equivalent to that of the current high-speed wheel/rail. The permanent magnet driving maglev train can save energy by 60 to 90% compared with wheel/rail train when traveling at low speed below 80 kilometers per hour and save energy by about 50% compared with high-speed wheel/rail train when traveling at high speed above 200 kilometers per hour. The invention can realize the interchangeability of maglev rail and common rail, leading the maglev rail to universality, networkability and compatibility in modern transportation.
