“…The two-dimensional model ignores the edge effect of the motor, and the accuracy of the simulation results is slightly reduced compared to the three-dimensional model [31]. However, the computational efficiency of the two-dimensional model can be greatly improved compared with that of the three-dimensional model [32]. Therefore, electromagnetic field simulation is conducted with the two-dimensional model in this paper.…”

Currently, vibration has been one crucial factor hindering the application of switched reluctance motor (SRM). Hence, it is of crucial importance to predict and suppress this undesirable vibration. This paper proposes a multi-physics analysis-based vibration prediction approach for SRM. It consists of three modules: digital controller and drive circuit module, electromagnetic field module, and mechanical module. In the mechanical module, it not only includes the influence of the stator, but also fully considers the influence of rotor, end cover, bearing, and other components of the motor on the system modal. Moreover, the vibration data under different control strategies areis obtained in real time, and data dynamic interaction between the three segments can be also be achieved. By combining the electromagnetic forces and the system structure modal, the vibration of SRM can be predicted. Finally, the effectiveness of the proposed method was verified on a 12/8 poles, 1.5KW SRM drive system test bench. The results demonstrate that the modal simulation method based on static pre-calculation achieves high accuracy, and the vibration spectrums predicted by the proposed method shows good agreement with the experimental results.

“…The magnetic field intensity in the air gap can be calculated as (12) Assuming the existence of a large air gap, the ampere turns required to produce the magnetic field intensity are given by (13) where is the number of winding turns per phase and is the peak phase current. Assuming a value for the peak current allowable in the machine, the number of turns per phase of the RSRM can be calculated as (14) If is the maximum allowable current density in the winding and is the number of phases, the area of the conductor is calculated as (15) The flux density in the stator pole can be calculated as (16) where is the area of the stator pole and is given by…”

“…However, the design of the machines is not described in detail, although the calculation of inductances and force by finite-element analysis (FEA) is covered extensively. An extensive theoretical analysis of a double-sided double-translator LSRM is described in [6], [16]. An LSRM based on a tubular structure to be used for short stroke lengths using a double-sided longitudinal flux configuration has been described in [8]- [10].…”

A standard design procedure for a single-sided and longitudinal flux-based linear switched reluctance machine is developed in this paper. The proposed design procedure utilizes the rotating switched reluctance machine design by converting the specifications of the linear machine into the equivalent rotary machine. The machine design is carried out in the rotary domain, which is then transformed back into the linear domain. Such a procedure brings to bear the knowledge base and familiarity of the rotary machine designers to design a linear machine effectively. This paper contains the illustration of the proposed design procedure for a 4.8-m-long prototype. An analysis procedure is developed with a magnetic model and results from it are verified with finite-element analysis prior to construction of the prototype. Extensive experimental correlation in the form of inductance versus position versus current and propulsion force versus position versus current to validate the analysis and design procedure is given in the paper. ).

“…Several of researchers have discussed advantages of switched reluctance type machine. Apart of it such as robust construction, low cost in mass production, fault tolerance, high efficiency, rugged behavior, and large thrust output over very wide speed [7][8][9][10]. Furthermore, the windings are concentrated rather than distributed, making them ideal for low cost of maintenance [10].…”

Nowadays, most of the researchers have put a lot of effort in designing the permanent magnet type of linear motor. However, due to resource problem occur recently to the permanent magnet material has led to increment of the material cost. This situation made the linear motor productivity is reduced. Because of this reason, most of linear motor manufacturers are prefer to development non-permanent magnet type to ensure product competitiveness and increase cost performance. Therefore, in this research, a switched reluctance linear motor was designed. The teeth shape has been varied in order to observed the effect to it's performance. As a result, the best model of switched reluctance linear motor with optimum teeth shape has been proposed. The performance of the model also has been compared to other similar type of linear motor and the permanent magnet type of linear motor.
