Linear switched reluctance motor as a high efficiency propulsion system for railway vehicles

A linear and a rotational switched reluctance drive with a large airgap are developed and manufactured for a test track of autonomous railway vehicles. The motor design, a coupled model and the results of finite-element-simulations are presented, along with the test bed structure and measurements. The design and control objectives are to maximize the efficiency and to minimize the acoustic noise at the given motor dimensions and the output power.
