Design and Operating Mode Study of a New Concept Maglev Car Employing Permanent Magnet Electrodynamic Suspension Technology

Based on the principle of permanent magnet electrodynamic suspension (PMEDS), a new concept maglev car was designed by using rotary magnetic wheels and conductor plate. It has advantages being high-speed, low-noise, environmentally friendly, safe efficient. The PMEDS is to use wheel (EDW) achieve integration levitation force driving force. generated repulsive eddy current field, reaction resistance. A simplified electromagnetic model EDW dynamics were established study operating mode. shows that can when rotational speed EDWs reaches certain threshold critical 600 rpm. With cooperation four EDWs, stable maximum height reach 7.3 mm. working 3500 At same time, movement status be controlled adjusting rear EDWs. functions propulsion, acceleration, deceleration, braking are realized feasibility system verified.
