Opis:
When the in-wheel motor is working, it will be affected by gravity, centrifugal force and electromagnetic force. These three kinds of mechanical loads will affect the mechanical stress characteristics of the in-wheel motor, and then affect the reliability of the in-wheel motor structure. In order to understand the influence of the above loads on the mechanical stress of the in-wheel motor, this paper takes a 15-kW built-in permanent magnet in-wheel motor as the research object. Based on the establishment of the electromagnetic field and structure field coupling analysis model of the in-wheel motor, the mechanical stress of the in-wheel motor under different mechanical loads under rated and peak conditions are calculated and analyzed, and the influence of different mechanical loads on the stress and deformation of the in-wheel motor are studied. The research results show that, regardless of the rated operating condition or the peak operating condition, the in-wheel motor has the largest mechanical stress and deformation under the combined action of centrifugal force and electromagnetic force, and the smallest mechanical stress and deformation under the action of gravity only; under the same load (except for the case of gravity only), the stress and deformation of the in-wheel motor under the peak operating condition are larger than those under the rated operating condition; and the maximum stress and deformation of the in-wheel motor appear at the rotor magnetic bridge and the inner edge of the rotor, respectively, so the rotor is an easily damaged part of the in-wheel motor.

Opis:
Praca prezentuje analizę wpływu awaryjnego hamowania pojazdu na temperaturę wirnika silnika przeznaczonego do zabudowy w kołach. Do wyznaczenia rozkładu pola temperatury wirnika, podczas procesu hamowania, przygotowano przestrzenny model wirnika i części elementów układu hamulcowego. Opracowany model 3D poddano dyskretyzacji i przeprowadzono szereg analiz numerycznych. Podczas obliczeń przeanalizowano zmianę temperatury elementów wirnika silnika pojazdu poruszającego się z prędkością 100km/h przy nagłym wyhamowaniu do 0km/h. W przeprowadzonych analizach zbadano wpływ uwzględnienia felgi na wyniki obliczeń.
The analysis of the impact of vehicle emergency braking on the temperature of the rotor of the motors designed for installation in the wheels is presented in the work. To determine the distribution of the rotor temperature field during the braking process, a spatial model of the rotor and parts of the braking system components was prepared. The developed 3D model was discretized and a number of numerical analyzes were carried out. The temperature change of the motor’s rotor elements of the vehicle's moving at a speed of 100km/h with a sudden braking to 0km/h was analyzed during the calculations. The impact of the wheel rim model on the results of calculations was taken into account in the carried out analyzes.

Opis:
The in-wheel motor is installed in wheels, and road excitation acts on the in-wheel motor directly through a wheel, which affects the flow field characteristics of the motor’s liquid cooling system, and affects the thermal field characteristics of the in-wheel motor. Aiming at this problem, the in-wheel motor drive system is taken as the research object in this paper. Firstly, the heat flow coupling analysis model of the in-wheel motor drive system is established by using the heat flow coupling theory. Then the vibration response of in-wheel motor stator and shell under different road excitation obtained from the previous study is taken as the load. Finally, thermal field characteristics of the water-cooled the in-wheel motor under different working conditions are studied, and the influence law of different speed and road grades on the thermal field characteristics is obtained. The results show that under the road excitation, the maximum temperature of each component of the in-wheel motor decreases due to the vibration effect of road excitation on the flow field of the cooling system, and the decrease of the stator and winding is the most obvious. Additionally, the higher the speed, the greater the road roughness coefficient, the greater the temperature drop of each component of the in-wheel motor. However, the thermal field distribution of local parts of the motor is relatively uneven under road excitation, which leads to greater thermal stress of the local parts and increases the risk of motor damage.

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:
The permanent magnet in-wheel motor (PMIWM) is a nonlinear, multivariable, strongly coupled and highly complex system. The key to the development and application of the PMIWM consists in the improvement of its control accuracy and dynamic performance. In order to effectively decouple the PMIWM, this paper presents a novel internal model control (IMC) approach based on the back-propagation neural network inverse (BPNNI) control method. First, theoretical analysis is conducted to show the existence of the PMIWM inverse system, to be modeled mathematically. The inverse system approximated and identified by the back-propagation neural network (BPNN) constitutes the back-propagation neural network inverse (BPNNI) system. Then, by cascading the BPNNI system on the left side of the original PMIWM system, a new decoupling, pseudo-linear system is established. Moreover, the 2-DOF internal model control (IMC) method is employed to design the extra closed-loop controller that further improves disturbance rejection and robustness of the whole system. Consequently, the proposed decoupling control approach incorporates the advantages of both the BPNNI and the IMC. Effectiveness of thus proposed control approach is verified by means of simulation and real-time hardware-in-the-loop (HIL) experiments.

Opis:
This paper presents the modeling, control and simulation of an electric vehicle with four in-wheel 15 kw induction motors drive 4WDEV controlled by a direct torque control DTC strategy, where two control techniques are presented and compared for controlling the electric vehicle speed: the first one is based on a classical PI controller while the second one is based on a fuzzy logic controller (FLC). The aim is to evaluate the impact of the proposed FLC controller on the efficiency of the 4WDEV taking into account vehicle dynamics performances, autonomy and battery power consumption. When the classical controller can’t ensure the electric vehicle stability in several road topology situations. To show the efficiency of the proposed new control technique on the traction system by 4WDEV. The vehicle has been tested in different road constraints: straight road, sloping road and curved road to the right and left using the Matlab / Simulink environment. The analysis and comparison of the simulation results of FLC and PI controllers clearly show that the FLC ensures better performances and gives a good response without overshoot, zero steady state error and high load robustness rejection, compared to the PI controller which is present an overshoot equal 7.3980% and a rise time quite important (0.2157 s with PI controller and 0.1153 s with FLC). As well as the vehicle range has been increased by about 10.82 m throughout the driving cycle and that the energy consumption of the battery has been reduced by about 1.17% with FLC.

Opis:
W artykule przedstawiono konstrukcję układu mechanicznego przełączania zazębienia pomiędzy silnikiem elektrycznym, przekładnią planetarną oraz piastą koła w napędzie elektrycznym zabudowanym w kole pojazdu. Układ mechaniczny umożliwia zarówno jazdę z napędem bezpośrednim (silnik elektryczny napędza bezpośrednio piastę koła pojazdu) oraz z napędem pośrednim (przez sprzężenie silnika elektrycznego z przekładnią planetarną). Napęd bezpośredni umożliwia uzyskanie wyższych prędkości obrotowych przy niższym momencie (np. w sytuacji jazdy na równej nawierzchni), natomiast napęd pośredni umożliwia uzyskanie wyższego momentu obrotowego w zależności od potrzeb w terenie. W pracy przedstawiono założenia projektowe, konstrukcję układu mechanicznego oraz obliczenia mechaniczne połączeń wielowypustowych mechanizmu. Praca została zrealizowana w ramach projektu „Innowacyjny elektryczny zespół napędowy do pojazdów użytkowych”, finansowanego ze środków NCBiR w ramach programu LIDER XI, zgodnie z umową nr LIDER/15/0060/L-11/19/NCBR/2020.
This article presents a design of a mechanical system for changing a gear meshing between electrical motor, planetary gear and the wheel hub in the electrical drive for installation inside the wheel of the vehicle. This mechanical system enables both: driving with a direct drive (electrical motor drives the wheel hub directly) and driving with an indirect drive (electrical motor is coupled to a planetary gear that drives the wheel hub). The direct drive enables to achieve higher rotational speeds with lower torque ( e.g. when driving on a straight road), while the indirect drive enables to achieve higher torque when driving in off-road conditions and according to higher torque requirements. The paper presents a design assumptions, structure of the mechanical system and mechanical calculations of the involute splines applied in the mechanical system. The study was carried out as part of the project "Innovative electric drive unit for commercial vehicles", financed by the National Center for Research and Development under the LIDER XI program, in accordance with the agreement no. LIDER/15/0060/L-11/19/NCBR/2020.
