For permanent-magnet linear motors (PMLMs), high-temperature rise can deteriorate their electromagnetic performance and limit their thrust output. A water-cooling system can be employed to reduce the temperature rise and to improve the thrust density. In order to study the thermal performance of a water-cooled, 14-pole, and 12-slot PMLM, a finite-element model and thermal network model are developed. Under continuous duty, the temperature distribution of this PMLM is investigated based on the two developed models, which are validated by experimental results. The effect of the water-cooling system and the impact of its parameters on the temperature rise are investigated. Then, the influence of the temperature rise on the motor thrust force and efficiency is studied. Finally, based on the finite-element model, thermal characteristics of this PMLM under short-time duty and intermittent duty are studied, and the relationship is obtained between the operation duration and the maximum allowed shorttime current, as well as the impact of load sustained rate.Index Terms-Finite-element analysis (FEA), permanentmagnet linear motor (PMLM), thermal analysis, thermal network model, water-cooled type.

“…[1][2][3][4] Various motors have been used in EVs, among which the permanent magnet synchronous motor (PMSM) is receiving strong interest due to its light weight, outstanding efficiency, superior power density, and potential for quiet operation as compared to the induction motor and the synchronous reluctance motor. 5 6 On the one hand, the prototype designs of the PMSMs are considered firstly by using the Finite Element method [7][8][9] with the state-ofthe-art materials 10 11 to improve the performance of the PMSM drives.…”

According to the characteristics of multiple-input multiple-output, nonlinearity, and strong-coupling of the permanent magnet synchronous motor (PMSM) for electric vehicle (EV) applications, a high performance control strategy based on neural network (NN) inverse (NNI) is proposed. The mathematical model of the PMSM is given, and then the reversibility of the PMSM is proved. After analyzing the inverse model of the PMSM, a NN is adopted to identify the inverse model of the PMSM. By combining the NNI, which is composed of a static NN and two integrators, with the PMSM, the original system is transformed into a pseudo-linear system. Therefore, it is easy to design the close-loop linear controller for the PMSM. Finally, the simulations are carried out, and the results confirm that the good static and dynamic control performance, high-precision speed tracking feature, and strong anti-interference capability can be achieved using the proposed strategy.

For permanent magnet linear motors (PMLMs), large temperature rise can damage their performance and limit their output. Water-cooling system can be designed to reduce temperature rise and to improve thrust density. In order to study the thermal performance of a water-cooled, 14-pole, 12-slot PMLM, the finite element model and the thermal network model are erected. For water-cooled type PMLM, the modeling difficulties are solved. Under continuous duty, the temperature distribution of this PMLM is investigated based on the two models, which is validated by experimental results. The effect of water-cooling system and the impact of its parameters on temperature rise are investigated. And, the influence of temperature rise on motor thrust force, and efficiency is studied. Finally, based on the finite element model, thermal characteristics of this PMLM under shorttime duty and intermittent duty are studied, which find the relationship of running time and the maximum allowed short-time current, and the impact of load sustained rate.
