Development of single linear induction motor for high-speed transit system

The linear induction motor based on local public transport has turned out to be more cost-effective in respect of energy cost as well as maintenance. This is due to the fact that linear induction motors constitute a strong durability rate, simple geometrical structure, large force application capability, and independent adhesiveness that make the motor more advanced than conventional motors based on propulsion systems. The single linear induction motor for urban transit modeled by T-type equivalent circuit model enhancement is proposed in this paper. For the proposed system, a double-sided and single-sided linear induction motor is described. For the linear induction motor, the converter control strategies are implemented which is responsive to the velocity and force/current control system, and their integrated performance propulsion drives is described in this paper. Finally, the efficiency and other intrinsic factors needed for the structure’s performance assessment are derived. The relationship between penetration depth and frequency is performed and the penetration rapidly drops at low frequencies and tends to stabilize beyond 10 Hz, with the Al having a relatively larger penetration depth. Finally, the performance analysis such as variation in the number of poles, mechanical air gap, penetration depth and frequency variations are calculated on the basis of various features.
