It is expected that HTS bulk materials can be applied to various electric devices. We have fabricated and tested a linear actuator with a single-sided primary and an HTS bulk secondary. The linear actuator was comprised of a zero-field-cooled YBCO bulk plate for the secondary (mover) and copper windings with iron core for the primary. In this study, to improve the characteristics of the linear actuator, we designed and fabricated a double-sided and short-secondary type of linear synchronous actuator which has a field-cooled YBCO bulk plate as a secondary (mover). The static synchronous thrust forces were measured. To evaluate the static characteristics of the linear actuator, we also numerically investigated the electromagnetic behavior within the bulk in an operational environment of the linear actuator by using a computer program based on the finite element method (FEM). The influence of the supercurrent distribution in the bulk on the thrust-angle characteristics of the model linear actuator are discussed.
