Opis:
In recent years, electric and hybrid vehicles have taken more and more attention due to their apparent advantages in saving fuel resources and reducing harmful emissions into the environment. Even though electric vehicles can solve the ecological problem, their operation is faced with a number of inconveniences associated with a limited driving distance from a single charge due to limited storage of energy from an independent power source and a lack of the required service and repair infrastructure. In hybrid and electric vehicles one of the main parameters is the curb weight, which affects energy consumption, vehicle speed, stability, controllability and maneuverability. In this regard, leading car manufacturers use parts with a low specific weight (non-metallic, aluminum alloys, etc.) in the design and also exclude some units from the design. Due to these technical solutions, the vehicle's operating is improved. One of the groups of parameters to be defined when designing a new electric vehicle is the parameters relating to the electric motor. The purpose of the article is determination of the mechanical characteristics of a two-rotor electric motor during magnetic flux control and assessment of the possibility of organizing the drive of the drive wheels of the vehicle. The electric motor has two mechanically independent outputs. For the study, an electrical equivalent diagram has been developed for the given two-rotor electric motor. A simulation model of the equivalent diagram has been built. Simulating the interaction processes of the rotors with the stator made it possible to obtain data for building the mechanical characteristics for each output of the electric motor. Analysis and processing of the mechanical characteristics data of the electric motors showed the conformity and the range of changes in the torque on each of the rotors when changing their slip and revolution, which are required when building algorithms for the operation of electric motor control systems as part of drives for various purposes. Analysis of the simulation results made it possible to assess the possibility of using the considered two-rotor electric motor for the drive of drive wheels in an electric and hybrid wheeled vehicle.

Opis:
The paper presents the results of FEM calculations of the electric motor of Toyota Prius 2nd generation. The study was conducted to establish, to what extent this motor differs from the model of a synchronous machine with internal permanent magnets, ie. the machine describable by mono-harmonic, linear model in Park coordinates (0dq). Suspicion, that the test motor is not a typical IPMSM motor is based on both the original form of magnetic excitation poles (on the rotor) and with almost completely open slots of the armature (on the stator) and the stator yoke relatively thin. Significant in this respect was to analyze the influence of local saturations of the magnetic circuit on the operation of the machine and the possibility of its modeling in coordinates 0dq. The results are important for the synthesis of controlling IPMSM motors. The test machine, despite the fact that formally it is synchronous machine with internal magnets (due to the overall construction and method of supply), do not satisfy the requirements of model 0dq and breaks the canon of the design of IPMSM machines
W artykule przedstawiono wyniki badań obliczeniowych MES silnika elektrycznego Toyoty Prius II generacji. Badania zostały przeprowadzone w celu ustalenia, w jakim stopniu silnik ten różni się od modelowej maszyny synchronicznej z magnesami trwałymi zagłębionymi, tj. maszyny opisywalnej monoharmonicznym, beznasyceniowym modelem we współrzędnych Parka (0dq). Podejrzenie, że badany silnik nie jest typowym silnikiem IPMSM wynikło zarówno z oryginalnego uformowania magnesowych biegunów wzbudzenia (wirnika), jak i z użycia w konstrukcji praktycznie całkowicie otwartych żłobków twornika (stojana), a także relatywnie cienkiego jarzma stojana. Istotne w tym aspekcie było przeanalizowanie wpływu lokalnych nasyceń obwodu magnetycznego maszyny na jej pracę i możliwość modelowania we współrzędnych 0dq. Uzyskane wyniki mają istotne znaczenie dla syntezy sterowania silników IPMSM. Badana maszyna pomimo tego, że jest formalnie maszyną synchroniczną IPMSM (z uwagi na ogólną budowę i sposób zasilania) wyłamuje się z modelu 0dq i kanonu konstrukcyjnego takich maszyn.

Opis:
The distortion of air gap magnetic field caused by the rotor eccentricity contributes to the electromechanical coupling vibration of the brushless DC (BLDC) permanent magnet in-wheel motor (PMIWM) in electric vehicles (EV). The comfort of the BLDC in-wheel motor drive (IWMD) EV is seriously affected. To deeply investigate the electromechanical coupling vibration of the PMIWM under air gap eccentricity, the PMIWM, tyre and road excitation are analyzed first. The influence of air gap eccentricity on air gap magnetic density is investigated. The coupling law of the air gap and the unbalanced magnetic force (UMF) is studied. The coupling characteristics of eccentricity rate, air gap magnetic density, UMF, phase current and vibration acceleration are verified on the test bench in the laboratory. The mechanism of the electro-mechanical coupling vibration of the BLDC PMIWM under air gap static eccentricity (SE), dynamic eccentricity (DE) and hybrid eccentricity (HE) is revealed. DE and HE deteriorate the vibration acceleration amplitude, which contributes the electromechanical coupling vibration of the PMIWM. The research results provide a solid foundation for the vibration and noise suppression of the PMIWM in distributed drive EV.

Opis:
This paper presents mathematical methods to develop a high-efficiency and real-time driving energy management for a front-and-rear-motor-drive electric vehicle (FRMDEV), which is equipped with an induction motor (IM) and a permanent magnet synchronous motor (PMSM). First of all, in order to develop motor-loss models for energy optimization, database of with three factors, which are speed, torque and temperature, was created to characterize motor operation based on HALTON sequence method. The response surface model of motor loss, as the function of the motor-operation database, was developed with the use of Gauss radial basis function (RBF). The accuracy of the motor-loss model was verified according to statistical analysis. Then, in order to create a two-factor energy management strategy, the modification models of the torque required by driver (Td) and the torque distribution coefficient (β) were constructed based on the state of charge (SOC) of battery and the motor temperature, respectively. According to the motor-loss models, the fitness function for optimization was designed, where the influence of the non-work on system consumption was analyzed and calculated. The optimal β was confirmed with the use of the off-line particle swarm optimization (PSO). Moreover, to achieve both high accuracy and real-time performance under random vehicle operation, the predictive model of the optimal β was developed based on the hybrid RBF. The modeling and predictive accuracies of the predictive model were analyzed and verified. Finally, a hardware-in-loop (HIL) test platform was developed and the predictive model was tested. Test results show that, the developed predictive model of β based on hybrid RBF can achieve both real-time and economic performances, which is applicable to engineering application. More importantly, in comparison with the original torque distribution based on rule algorithm, the torque distribution based on hybrid RBF is able to reduce driving energy consumption by 9.51% under urban cycle.

Opis:
To achieve high-efficiency and stable brake of a front-and-rear-motor-drive electric vehicle (FRMDEV) with parallel cooperative braking system, a multi-objective optimal model for brake force distribution is created based on radial basis function (RBF). First of all, the key factors, which are the coefficient of brake force distribution between the front and rear shafts, the coefficient of brake force distribution at wheels, the coefficient of regenerative brake force distribution between front and rear axles, that influence the brake stability and energy recovery of the FRMDEV are analyzed, the fitness functions of brake stability and energy recovery are established. Secondly, the maximum allowed regenerative brake torque influenced by the state of charge of battery is confirmed, the correction model of the optimal distribution coefficient of regenerative brake force is created according to motor temperatures. Thirdly, based on HALTON sequence method, a two-factor database, vehicle velocity and brake strength, that characterizes vehicle operation is designed. Then an off-line response database of the optimal brake force distribution is established with the use of particle swarm optimization (PSO). Furthermore, based on hybrid RBF, the function model of the factor database and the response database is established, and the accuracy of the model is analyzed. Specially, the correlation coefficient is 0.995 and the predictive error variance is within the range between 0.000155 and 0.00018. The both indicate that the multi-objective distribution model has high accuracy. Finally, a hardware-in-loop test platform is designed to verify the multi-objective optimal brake force distribution model. Test results show that the real-time performance of the model can meet the demand of engineering application. Meanwhile, it can achieve both the brake stability and energy recovery. In comparison with the original brake force distribution model based on the rule algorithm, the optimized one proposed in this paper is able to improve the energy, recovered into battery, by 14.75%.

In order to develop a PM BLDC motor control system, which will be tolerant of selected faults, simulation work was first performed and then verified on a universal test stand. The results were published in earlier works. The next stage of works was the implementation of previously developed algorithms on the target research test stand – in this case, the prototype vehicle. This last stage of the laboratory work has been presented in this article, i.e. it has been presented the results of experimental research related to the reproduction of rotor angle position, used after the detection of a rotor position sensor fault. A new test stand with the laboratory prototype of a vehicle with two PM BLDC motors is presented. A zeroth-order algorithm (ZOA) was used as a fault compensation method. The effectiveness and usefulness of the previously proposed methods have been confirmed.

Permanent magnet motors are more and more frequently used in various applications. In this group motors with a trapezoidal EMF deserve a special attention. They are characterized by a simple construction, high efficiency and high torque overload. A certain drawback of BLDC motors are difficulties with an operation at a speed above the nominal value. The article presents the results of investigations into the variablestructure electronic commutator designed for the drive of a small electric vehicle equipped with BLDC motors. Such a solution allows extending the standard range of the drive's speed. The considerations contained in the article focus on the possibilities and effects of regeneration mode in the proposed topology of converter. A theoretical analysis has been presented as well as computer simulations carried out by means of Matlab- Simulink, which were then verified at a laboratory. The tests were finished with trias conducted using a small electric vehicle Elipsa.

Opis:
This paper presents a review of the electromagnetic field and a performance analysis of a radial flux interior permanent magnet (IPM) machine designed to achieve 80 kW and 125 Nm for an electric and hybrid traction vehicle. The motor consists of a 12-slot stator with a three-phase concentrated winding as well as an 8-pole rotor with V-shaped magnets. Selected motor parameters obtained from an IPM prototype were compared with the design requirements. Based on the electromagnetic field analysis, the authors have indicated the parts of the motor that should be redesigned, including the structure of the rotor core, aimed at enhancing the motor’s performance and adjusting segmentation for magnet eddy current loss reduction. In addition, iron and PM eddy current losses were investigated. Moreover, transient analysis of current peak value showed that the current may increase significantly compared to steady-state values. A map of transient peak current load vs. torque load plotted against rotor speed was provided. Based on the numeric and analytical results of physical machine parameters, the authors indicate that collapse load during the motor’s operation may significantly increase the risk of permanent magnet (PM) demagnetization. It was also found that collapse load increases the transient torque, which may reduce the lifetime of windings.

Opis:
For short distance (neighborhood) city transport of people, electric driven vehicle with advanced energy storage and electronic control system could assure fulfill essential requirements. range, acceleration ability and grade ability of electric driven small size city vehicle depend on: total vehicle mass, energy storage type and size, vehicle exploitation conditions (motorway, city traffic). Energy storage type and size optimization and full utilization of regenerative braking system leads to significant amount energy saving. Regenerative braking is particularly important in city traffic, where a lot of acceleration/braking cycles occur. Advanced secondary energy source consist of electrochemical battery and stack of supercapacitors. Using supercapacitors as an additional energy source makes it possible to improve battery life cycle and simultaneously to decrease the exploitation costs of electric vehicle. Short charging and discharging times of supercapacitors give ability to quick accept large amount of energy. In order to cooperate with batteries, a power electronic converter is necessary. Knowledge of vehicle energetic parameters could be obtained by model based simulation than verified by research testing. To estimating the energy consumption, energy recovery, range, acceleration and grade ability, simulation in MATLAB environment has been performed applying special low speed vehicle drive cycle based on ECE-15 driving cycle. The results of simulation are presented in this paper

W artykule został przedstawiony model matematyczny bezszczotkowego silnika synchronicznego z magnesami trwałymi o sinusoidalnym rozkładzie SEM (PMSM). Integralną częścią artykułu jest również przedstawienie propozycji układu sterowania oraz dokonanie analizy możliwych jednostek centralnych, w których algorytmy sterowania silnikiem mogą zostać zaimplementowane.
The paper concerns different aspects of driving the permanent magnet synchronous motor (PMSM). The excitation in the PMSM motor is provided thanks to a permanent magnet instead of the field windings. Special construction causes that the PMSM motor has sinusoidal back EMF. The motor requires sinusoidal stator currents to produce a constant torque. Mathematical analysis (d, q model). is presented in the paper. Elements of the Park transform which enables calculating d, q variables from motor phase variables are also given. The mathematical model is the basis for proposition of a control driver. Different central processing units are considered: digital signal processor (DSP), microcontrollers with DSP support and programmable logic devices (especially field programmable logic devices). The most popular is the digital signal processor. However, dynamic development of microcontrollers and logic devices enables applying them as a central processing units in the control drivers. All the more so because modern microcontrollers and logic devices support digital signal control thanks to (among others) build-in multiply and accumulate blocks. The use of special DSP blocks is facilitated by means of libraries and tools like MATLAB&Simulink.
