“…Similar to that of SRM, there are also variable inductance based dynamic modeling approaches for synchronous motors. If the cross coupling effect is considered, the flux linkage equation becomes: (6) where ψm is the flux linkage from the permanent magnet (PM) in case of PM synchronous motor (PMSM), Ldq and Lqd are the mutual inductances in the dq reference frame. Obviously, to consider the cross coupling, at least one matrix has to be constructed compared to the current-flux linkage approach.…”

“…Tesla is using a threephase induction motor with copper rotor bars in its Model S electric vehicle [1]. The switched reluctance motor is a lowcost and robust alternative for traction applications and it does not have coils or permanent magnets on the rotor [6]. The dynamic model of an electric motor is dependent on the type of motor and, as it will be discussed in Section II, it needs to incorporate the nonlinear flux linkage characteristics.…”

In order to study the design and electromagnetic heat of electric vehicle hub motor based on finite element simulation model, the electric vehicle hub motor is designed by using finite element method, and the simulation model based on finite element method is established. The maximum speed of electric vehicle, the number of poles and the temperature field are collected and analyzed to verify the operation effect of the simulation model. The results show that from the data of the start-up process, about 40ms, the speed is accelerated rapidly and it is in the exponential rising stage. Until 150ms, the speed starts to reach a stable state, and its speed reaches about 189rmp. From the point of view of the pair pole number, the power factor of the motor decreases linearly with the increase of the pair pole number; from the point of view of the temperature field, when the height of the stator yoke remains unchanged, the temperature at the highest temperature reaches stability between 25 and 30 minutes, and its stable temperature reaches 156°C. When the height of the stator yoke increases by 20mm and 30mm, the temperature curve at the highest temperature almost coincides and the stable temperature of them is 123°C. Based on the finite element simulation model, the simulation model of electric vehicle hub motor is designed. Through the verification, it basically meets the expectation, and its optimization effect runs well and meets the expectation. Although there are still some shortcomings in the research process, it can also contribute to the development of the automotive industry, and has a certain reference and guidance role for future research, which is a research subject closely following the direction of development.

“…Nowadays, SRM gets more and more attention as the in-wheel motor due to its excellent advantages: a simple structure, ruggedness, fault tolerance ability, high-speed operation capability, high-power density, and low manufacturing cost. However, these advantages are overshadowed by its inherent torque ripple, vibration, and noise, which seriously hindered the applications of SRM for in-wheel motor [8][9][10][11].…”

This paper studies the unbalanced radial force of in-wheel switched reluctance motors effect on vehicle performance under stability condition. First, the IWM-EV vehicle model which highlights the new factors of the rotor, stator, SRM vertical force, and airgap deflection was adopted. And the vehicle comparison models were established to make a contrastive study about IWM-EV new structure effects. Then, Routh’s stability criterion method was adopted to judge the vehicle system’s stability condition. It includes two parts: characteristic polynomial of the vehicle system which is served to calculate the IWM-EV system Routh array and Routh’s stability criterion which is used to judge the vehicle system’s stability condition. The effect of the new structure on vehicle performance was further discussed under stability condition. It mainly includes two aspects: vehicle vibration mode analysis which is used to study vehicle vibration characteristics and amplitude-frequency analysis which is served to research transfer response characteristics of the vehicle system. The result shows that the new structure of IWM-EV has a negative effect on vehicle stability performance. The SRM vertical force will change vehicle stability characteristic. In some severe cases, it will even destroy IWM-EV’s stability.
