A laboratory model of a 3-phase linear induction motor for use in traction is designed and constructed with the primary winding in the moving part and the secondary forming the track. Two type of track designed for use at stations and between station are presented. The effect of the linear configuration of the motor on the flux distribution and its harmomic contents is investigated. An evaluation of the forces produced by the interaction of the currents in the primary and secondary circuits is made and the effect of the phase angles of currents on these forces is studied. A simplified equivalent circuit of the motor is presented. A method for measuring the linear speed of the motor is developed. The feasibility of using such a motor as a traction motor in the light of its overall performance and the cost of such a transport system is discussed.
