Fast Analytical Model for Switched Reluctance Machines

Purpose This paper aims to deal with a performance comparison of an 8/6 radial-flux switched reluctance machine (RFSRM) and an axial-flux switched reluctance machine (AFSRM), presenting equivalent active surfaces. Design/methodology/approach An axial machine was designed based on the equivalent active surfaces of a radial one. After estimating the machine inductances with a reluctance network, finite elements numerical models have been implemented for a more precise inductance determination and to estimate the electromagnetic torque for both machines. Finally, the AFSRM was thoroughly examined by analyzing the impact of some geometric parameters on its performance. Findings The comparison of the RFSRM and AFSRM at equivalent active surfaces showed that the obtained axial machine is more compact along with an improvement in the electromagnetic torque. Practical implications The equivalent AFSRM is more compact, therefore more interesting for transport and on-board applications. Originality/value The RFSRM and AFSRM performance comparison using the same active surfaces has not been done. Moreover, the AFSRM presented has a rare design with no rotor yoke and where the rotor teeth are encapsulated in a nonmagnetic structure, allowing a more compact design.

This paper describes a novel motor which is an improved SRM (Switched Reluctance Motor) and a study of its driving circuit. Our objective is applying the motor to the EV(Electric Vehicles) for one of the solution of the rare earth issue. In order to realize it, control method of the motor and driving circuits must be developed. For the control method, DC chopper, phase controller and inverter are proposed so far. On the other hand, SRM has strong nonlinearity and some disadvantages. Due to the nonlinearity, computer simulation of the motor and its driving circuits are quite difficult. Therefore, we had to evaluate our method by experiments using real hardware. In this paper, at first, structural feature of the novel motor is explained. Then a principle of commutation circuit will be described. In addition, this paper presents a structure and operation of constant-current power supply which plays important role for control of the novel motor. Finally, results of experiments of the motor drive by using our driving circuits will be presented.
