ABSTRACT
Linear reluctance synchronous motors (L-RSM) are characterized by a short primary magnetic core with uniform slots that host a distributed three-phase ac winding and a long variable reluctance secondary. There are two main applications, which refer to: medium- and high-speed transportation; and low-speed short travel industrial applications. L-RSMs are always supplied from PWM voltage source inverters. The chapter deals with the steady-state theory and performance of L-RSM with notable attention to its electromagnetic design. It introduces some main vector control possibilities through their potential characteristics, to assist in the design. The chapter provides a rather new vector control scheme for propulsion and the direct thrust and normal force control for integrated propulsion and suspension control. A vector control system based on the “active flux” model transplanted from rotary RSMs is introduced for propulsion-only control.
