This paper describes single-sided linear induction motors (LIMs) with a short primary member. In these machines a solid-plate conductor is usually used for the secondary. We here propose the partial adoption of wound secondary members in LIMs. The characteristics of such machines are summarized as follows. 1. Basic characteristics: The wound secondary shortens the magnetic clearance and makes the characteristics of the machine superior to those of the solid-plate conductor version. In addition, we can improve the thrust and efficiency characteristics by applying the proportional shifting method. 2. Primary and secondary winding scheme: Parallel connection is appropriate for the primary and independently shorted-circuit scheme in order to obtain stable performance. 3. Transient phenomena at the boundary between the wound secondary and the solid-plate secondary: Undesirable phenomena develop at the boundary, especially at the end of the solid-plate conductor. Thus, we propose a novel boundary structure that yields stable transient performance.
