Design and Drives Simulation of an In-Wheel Switched Reluctance Motor for Electric Vehicle Applications

A study about optimum stator pole design of Axial-gap switched reluctance motor

“…The minimum phase inductance is the point when they are unaligned. According to (3), if the windings are excited when the gradient of the phase inductance is positive, SR motor can get positive torque. In the paper, the excitation is begun at unaligned position and is end at 1/3 of the electrical cycle as normal excitation method.…”

“…It is a quite serious problem especially at In-Wheel EV equips its motors at out of its body. Because of that, we focus attention on Switched Reluctance (SR) motor as In-Wheel motor [1]- [3]. SR motor is the motor that utilized the reluctance torque originated in magnetic saliency between stator poles and rotor poles [4]- [5].…”

Control methods of the switched reluctance motor in electric vehicle during acceleration

“…Substituting from equation (8) into equation (7) taking into account the specified modes of operation, the motor phase current can be obtained for each rotor position range, included in Figure 2, as:…”

“…Due to simple and rugged motor construction, low weight, potentially low production cost, undemanding cooling, excellent torque-speed characteristics, high torque density, high operating efficiency, and inherent fault tolerance, switched reluctance motor (SRM) drives are emerging as an attractive solution for electric vehicle (EV) applications [4][5][6][7][8][9][10][11][12][13]. Traction performances of EVs depend on the performances of SRM drives.…”

Application of an in-wheel direct drive motor based on switched reluctance motors for low-power electric vehicles

“…As can be seen in the literature, different motor types have been used for in-wheel applications and most of them are permanent magnet (PM) motors. Although PM motors have higher torque density and lower weight values, magnets limit the speed range of motors [4]. In addition, the price and the supply of the PMs with rare-earth material such as neodymium and dysprosium are serious problems for EVs.…”
