Abstract
Linear motors are featured with direct linear motion, but it has a low torque density due to the presence of edge effects. The torque density of five-phase linear induction motor can be improved by injecting high order harmonics of the magnetic field. The purpose of the paper is to present the optimal control strategy of a five-phase linear induction motor based on a rotor-flux-oriented control scheme, which promoted the performance of linear induction motor. The proposed control scheme is confirmed using finite element modeling and experimental tests. And the temperature distribution of the LIM shows temperature rise of the motor under this strategy is within the specified range.
