Propulsion and guidance simulation of HTS bulk linear synchronous motor taking into account E-J characteristic

We have proposed a new linear synchronous motor (LSM) theory which is based on an idea of considering the pinning force as synchronizing one in using current-carrying-armature-winding instead of permanent magnets. We have carried out basic experiments on two-dimensional electromagnetic forces produced in HTS bulk within DC-magnetic-field. As a result, we found that HTS bulk magnet in a cooling case can be levitated and guided stably according to the flux conditions between bulk and DC magnet. HTS bulk LSM can produce propulsion, levitation and guidance forces from zero speed, and be used in many applications. This paper proposes HTS bulk LSM analyzed and designed taking into account E-J characteristic. The LSM can produce stable guidance force without control. The LSM propulsion and guidance motion can be simulated numerically only by a simple propulsion control, which is not only closed-loop control but also open-loop control
