Abstract :
A method of designing low-speed single-sided linear induction motors (SLIMs) for urban transit with maximum speed of 70 km/h is described. The SLIMs can be used not only for Maglev vehicles, but also for the vehicles of the LIM/wheel systems in which the SLIMs are used for propulsion and the wheels for suspension and guidance. The effects of varying principal design parameters on the performance characteristics and the motor weight are numerically investigated. The effects of small changes of the LIM specifications are also shown. The motor weight, the cost of secondary materials, and the energy consumption for a typical route (including regenerative braking operation) are considered as the criteria of goodness for SLIMs. A design example is tackled using the sequential unconstrained minimization technique and the simplex method.<>
