In this paper, we propose a novel block feeding method for use in linear induction motors. The proposed method involves shifting of the excited section at every coil. Using the proposed method, the excited-section length can be shortened greatly compared with that in the ordinary method shifting at every block section. Thus, the power consumption becomes lower, improving efficiency. In addition, by short-circuiting the coils at both ends of the excited section during shifting, continuous power supply becomes possible, and thus electric transient phenomena are reduced. We confirm the validity of the method by finite element analysis and experiments.
