Mass reduction and propulsion control for a permanent-magnet linear synchronous motor vehicle

This paper deals with fundamental research on a new container transport system utilizing a permanent-magnet (PM) linear synchronous motor (LSM), and proposes a concept of mass reduction and propulsion control for container transfer operation. By applying the repulsive lift force in the PM LSM, a large percent of vehicle weight is compensated for, and it needs less thrust force to propel the vehicle. An experiment which involved propelling the test vehicle by reducing its weight by about 85% was conducted successfully.
