Simulation of high-speed linear-induction-motor end effects in low-speed tests

The paper presents two new possibilities of simulating end effects and transverse edge effects of a high-speed linear induction motor in a rather low-speed test if certain equivalence conditions are satisfied. The basis of simulation is to keep the flux-density distribution in the airgap, as well as in the exit and entry zones, the same in the simulated l.i.m. as in the actual l.i.m. It is demonstrated that a realistic simulation may be obtained in practice. Two examples are given which show the parameter values to simulate a fullsize high-speed l.i.m. by (a) a low-speed l.i.m. and (b) an arch motor.
