This paper describes single-sided Linear Induction Motors (LIMs) with a short primary member. In the machines, a solidplate conductor is usually used for the secondary. In this study, we propose partial adoption of wound secondary members in the LIMs. Characteristics of the machine are summarized as follows:
1) Basic characteristics: The wound secondary shortens the magnetic clearance and makes characteristics of the machine superior compared with the solid-plate conductor one. Further, applying the proportional shifting method, we can improve thrust and efficiency characteristics.
2) Primary and secondary winding scheme: Parallel connection is proper for the primary and independently short-circuited scheme for the secondary to obtain stable performance.
3) Transient phenomena at the boundary between the wound secondary and the solid-plate one: In the boundary, especially at the end of the solid-plate conductor, undesirable phenomena develop. Thus, we propose a novel boundary structure, which yields stable transient performances.
