A novel performance study for linear induction motors considering end effects

We present an analysis of the single-sided linear induction motor with a solid-steel reaction plate. By solving for the two-dimensional field distribution in the air gap and in the secondary, the mutual reactance and secondary impedance are derived account for the longitudinal end effect factor. Meanwhile, other electromagnetic effects, such as skin effects, the thickness of the secondary plate and transverse edge effects are taken into account. Traditional methods for solving the performance by using the electromagnetic fields are very difficult to achieve. So we propose an easier method to calculate the performance of the single-sided linear induction motor. Simulation results produced by this proposed analytical technique have a good agreement with the traditional results under constant- current conditions. The analysis is valid over a wide range of operating conditions, and is useful for design studies.
