The modern trends in converting a gasoline-powered vehicle (Diesel, Petrol, or CNG) into an electric vehicle requires an appropriate redesign in the placement of new electrical components. These new trends of approaches are often applied to vehicles that are manufactured for the sole purpose of operating a fully electric vehicle without any gasoline components. However, in the case of retrofitting a gasoline-powered vehicle into a battery-powered electric vehicle (EV), different approaches are used in an already running vehicle that can be converted into a fully functioning Electric Vehicle. This results in better recycling, environment-friendly usage of old vehicles, and a massive improvement in air pollution levels. A minimum amount of maintenance while owning an Electric Vehicle is a key factor where the automobile industry gains attention for buyers or customers. The conversion of traditional or conventional vehicles into fully functioning Electric Vehicles has gained preference in recent years. However, the components used in an Electric vehicle are to be discussed to fully assess the working of an EV in the process of this conversion. In this paper, we shall focus particularly on the implementation of such conversions and controlling of the electric vehicle through different types of Electric Vehicle Control. The functions of each component in an Electric Vehicle Controller or just a controller in general, show different approaches to communicating with each other to achieve an efficient range and performance of the particular electric vehicle. The relations between these components inside of an EV controller can be studied by their energy flow, circuitry, and their functions. Control Area Network (CAN) is also considered as a topology to determine the aforementioned working of each component. Fault diagnosis, charging status, and battery capacity status are some of the many factors that are applicable after installing a controller within the Electric Vehicle.

“…The essence of this paper is to estimate the unbalanced force, reverse and add to the control current, used to offset the unbalanced force. Based on previous researches [21][22][23], an HRF-based imbalance compensation controller is proposed. The structure used in feedforward compensation is shown in Fig.…”

The existing imbalance compensation strategies for magnetic suspension motors mainly focus on the mass unbalance force, ignoring the effects of the unbalanced magnet pull (UMP). This paper studied the vibration mechanism and compensation strategy of magnetic suspended permanent magnet synchronous motor (PMSM) under the influence of UMP. Firstly, an analytical model of the flux density was established based on equivalent magnetic circuit method, then the analytical expressions of UMP was deduced by Maxwell stress tensor method. Furthermore, an unbalanced compensation method based on hypothetical reference frame (HRF) transformation was proposed. The stability of the closed-loop system with compensation was analyzed based on the complex-coefficients theory. The proposed model and compensation strategy were verified by the simulations and experiments. The results indicate that the proposed compensation strategy can achieve effective suppression of the magnetic rotor vibration.

“…Regarding the on-line monitoring of the rotor eccentricity fault, literature [27] provides a comprehensive overview of the status monitoring, the fault diagnosis of induction motors related to rotor eccentricity faults, and summarises the techniques that can be used to detect rotor eccentricity faults. Refer to the method for detecting the radial position of the rotor of a bearingless motor [28,29]. In the circumferential direction of the stator, every 90 deg (mech.deg) is divided into a part, and a displacement sensor (such as an eddy current sensor and a Hall sensor) for detecting the radial position of the rotor is installed between the two parts.…”

Due to the dual air-gap topology of the direct-drive permanent magnet motor with inner enhance force (IEF-DDPMM), the radial EM exciting force generated in the inner and outer air gaps when the rotor is eccentric will act on the same rotor, and the unbalanced magnetic pull (UMP) on the rotor will reduce the fatigue life of the rotor structure and bring many problems such as vibration and noise. Therefore, the rotor UMP compensation method of IEF-DDPMM based on modular winding d-axis current injection is proposed to suppress the harm caused by eccentricity. The expression of electromagnetic (EM) exciting force considering the cogging effect and current time harmonic without rotor eccentricity faults is derived by the analytical method. Also, the EM exciting force newly introduced due to the rotor eccentricity is analysed. The effects of different eccentricity types on torque characteristics, the fatigue life of the rotor structure and stator vibration of IEF-DDPMM are compared and analysed by the FEM. Finally, the IEF-DDPMM rotor eccentricity models are optimised based on the method. The performance of the motor before and after rotor UMP compensation is evaluated by FEM. The results show that the proposed method is correct and effective.
