This paper describes single-sided Linear Induction Motors (LIMs) with a short primary member. In the machines, a solid plate 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.
