“…Therefore, techniques used for minimising end effect in short primary and also short secondary LSMs is useful for SSLFSMs, which is electrically more like LSMs. The end effect in short primary LSMs is considerably low in comparison with the long primary type [37]. As mentioned above, the presented motor is a short primary type, so its end effect is expected to be considerably low.…”

A dq model representation of segmented secondary linear flux switching motors (SSLFSMs) is investigated. In these motors, the armature and field windings are both mounted in the primary slots and the secondary is only composed of simple laminated segments. This type of motors inherits both merits of high force density from linear synchronous motors and simple secondary structure from linear induction motors. Due to its simple and consequently low-cost secondary structure, it is applicable to transportation systems like Maglev. Position and speed control of this motor is essential for rail transportation applications. Therefore, derivation of an appropriate analytical model for control purposes is needed. An analytical method to represent the dq model of SSLFSMs is presented. Employing this method, the d-and q-axis inductances and the developed electromagnetic thrust and normal force are calculated. To verify the proposed model, three different finite-element methodbased models are studied and one is chosen as the basis for comparison. All results obtained by the analytical model are verified by this finite-element method-based model. Moreover, a prototype of SSLFSMs is built to validate the study.

“…It is necessary to study the key electromagnetic parameters in the mathematical model of the motor in combination with specific topological structures and inter-segment transitions. Establishing an accurate simulation model that is closer to the actual physical state and has realistic engineering achievability is of great significance for motor performance optimization and control research, and facilitates united simulation of motor and system [10]- [12].…”

By analyzing the relationship between the electromagnetic parameters and the secondary position during the primary and secondary coupling transition of the segment winding permanent magnet linear synchronous motor (SW-PMLSM), the variable parameter mathematical model of the rotor side of the SW-PMLSM is established. Taking the three-stage primary lifting system as an example, the dynamic process of the whole system is simulated and analyzed. According to the characteristics of its parameters, the segmentation vector control is obtained as the best stability control method. However, in practical applications, in order to save costs, the segmented linear motor often adopts the effective section parallel power supply mode, and the SW-PMLSM parallel power supply model is obtained by approximate simplification. This paper proposes a SW-PMLSM high-efficiency V/f control method, which combines the advantages of traditional V/f control and field-oriented control. It does not need to install position sensor, and can realize simple and high-performance motor drive. Finally, simulation and experimental results are provided to validate the effectiveness of the fidelity of the proposed strategy.INDEX TERMS SW-PMLSM, vector control, effective segment parallel power supply, variable parameter mathematical model, simulation modeling, efficient V/f control.
