“…There are three excitation sources, namely permanent magnetic, armature and axial coils in the motor. Control of these excitation sources to make the motor run in different modes for vehicle applications has been demonstrated [242]. A novel algorithm for designing the set of PI/PID controllers for stabilizing the current and speed loops of a high-speed and high-power flywheel energy storage system using a PMSM is demonstrated in [243].…”

The rapid consumption of fossil fuel and increased environmental damage caused by it have given a strong impetus to the growth and development of fuelefficient vehicles. Hybrid electric vehicles (HEVs) have evolved from their inchoate state and are proving to be a promising solution to the serious existential problem posed to the planet earth. Not only do HEVs provide better fuel economy and lower emissions satisfying environmental legislations, but also they dampen the effect of rising fuel prices on consumers. HEVs combine the drive powers of an internal combustion engine and an electrical machine. The main components of HEVs are energy storage system, motor, bidirectional converter and maximum power point trackers (MPPT, in case of solar-powered HEVs). The performance of HEVs greatly depends on these components and its architecture. This paper presents an extensive review on essential components used in HEVs such as their architectures with advantages and disadvantages, choice of bidirectional converter to obtain high efficiency, combining ultracapacitor with battery to extend the battery life, traction motors' role and their suitability for a particular application. Inclusion of photovoltaic cell in HEVs is a fairly new concept and has been discussed in detail. Various MPPT techniques used for solar-driven HEVs are also discussed in this paper with their suitability.

“…Figure 8 shows Currents waveform during changing the multi-step transmission. Depending on the changing the multi-step transmission, the voltage and phase of each phase are different, so the current shows different values for each condition [9,10,13]. Figure 9 is torque waveform displayed when the current waveform of figure 8 is inputted.…”

Background/ Objectives: Apply the electromagnetic multi-step transmission method to expand the average efficiency area of electric vehicles. In this paper, analyze the influence of torque caused by shift shock due to electromagnetic multi-shift. Methods/ Statistical analysis: Research has been conducted to extend the average efficiency range of the motor by applying the electromagnetic multi-step transmission method. In addition, we analyze the effects of shift shocks on the torque of the motor through finite element analysis methods(FEM) analysis. Findings: In this paper, we study the characteristic analysis of the electromagnetic multi-step transmission method of interior permanent magnet synchronous motor. In addition, we analyzed the influence of the shift shock due to the electromagnetic multi-shift on the torque. It has been confirmed that the average efficiency section of the motor is widened by the electromagnetic multi-step transmission method, and it has been confirmed that the difference in the voltage in the shift section adversely affects the torque of the motor. It has been confirmed that the influence on the torque is different based on the shift point. Improvements/ Applications: Analyzes and derives attributes thought FEM analysis using voltage source analysis and current source analysis.

A solid rotor permanent magnet synchronous motor (PMSM) is developed for the electric propulsion part in electric vehicles (EV). The rotor in this kind of motor is composed of splits solid bodies, interior permanent magnets and starting bars. Wedges and bars are shot circuited by end rings that promote the generation of starting torque jointly. While PMSM used in EV, it may need to start frequently at different load, which would cause eddy losses in rotor and related to thermal demagnetization of permanent magnet directly. In this paper, a prototype of 30kW solid rotor PMSM is proposed, and numerical calculation models for thermal analysis are established. The 2D electromagnetic fields were calculated by using finite element method (FEM) first and motor losses in rotor were determined. From the analysis of fluid analysis of air in airgap, an effective coefficient of heat transfer is proposed to deal with the complex heat exchanges between rotor and stator. Then steady thermal field is analyzed, and influences of motor fan, loads and stray loss on rotor temperature distribution were studied. Some associate test work has been done with results in a good agreement with the analysis data. Some reasonable conclusions were obtained, which can provide some help for the design of this kind of PMSM and its application in EV.
