“…A Machine in EVs can be connected by driveline or directly connected to the wheel. In-wheel motor technology involves fitting a motor in the wheel hub, and the output torque is directly transferred to the wheel, which reduces the retarder, traditional clutch, and other mechanical differentials [15]. The use of in-wheel motors also improves on many aspects of all-wheel drive (AWD) driving systems.…”

In electrical vehicle applications, power density plays a significant role in improving machine performance. The main objective of this paper is to design and analyze the performance of in-wheel outer rotor permanent magnet synchronous motor (PMSM) used in electric vehicles based on a previously designed model. The key challenge is to achieve the best machine performance regarding the highest torque density and lowest torque ripple. This work also aims at reducing the machine cost by using permanent magnet (PM) material, which has less energy density than the PM used in the previously designed model. An optimization procedure is carried out to improve the generated torque, keeping the same aspects of size and volume of the selected machine. On the other hand, the other specifications of the machine are taken into consideration and are maintained within the acceptable level. According to their major impact on the machine’s performance, the most important parameters of machine designing is selected during the optimization procedure. This proposed machine is implemented and tested using the finite element software package “MagNet 7.4.1” with Visual Basic 16.0 programming language and MATLAB 9.5 Simulink for post-processing.

“…The entire system includes such main functions as automatically supplying goods, detecting, classifying and moving in and out of the storehouse. This paper stresses the mechanical components of MASM system, namely the conveyer belt with frequency converter, the material automatic recognition, the material classifying into the storehouse and the moving cargo out of the storehouse several units [7][8][9]. The technical Process of MASM: (1) Goods are moved to the parallel belt conveyor in the cargo buffer system by the manipulator; 10, then the discharging cylinder will push the goods out of the storage buffers and send them onto the belt conveyor transmission mechanism; (6) Moving the goods to the beginning of stacking unit with parallel belt going forward in the system.…”

In this paper a PLC control system is designed to control the sorting, transmission and loading/unloading in the manufacturing, in view of the defects of the relay control system which usually has poor reliability and bad flexibility in use. On the basis of the superior performance of PLC control system and the working principle of frequency converter, AC transducer drive technology is applied to achieve stable starting, reliable operation and low breakdown rate in the assembly line of manufacturing. In the design of the upper monitoring system, the functions of parameter settings, process monitoring and control, data processing, fault location can be well implemented via configuration software. The research work of this paper will lay a solid foundation for the design of material automatic sorting system based on the PLC controller.

“…However, the specific methods of the pure electric ABS actuation are still rarely discovered in the research and technical publications. Within this context, in particular, Zhou et al [6] have investigated the method of pulse width modulation of in-wheel brushless direct current motors with its subsequent implementation in the ABS controller. Other relevant study has been introduced by Mi et al in [7], where the iterative learning control method is proposed for an electric ABS.…”

Anti-lock braking functions of electric vehicles with individual wheel drive can be effectively realized through the operation of in-wheel or on-board motors in the pure regenerative mode or in the blending mode with conventional electro-hydraulic anti-lock braking system (ABS). The regenerative ABS has an advantage in simultaneous improvement of active safety, energy efficiency, and driving comfort. In scope of this topic, the presented work introduces results of experimental investigations on a pure electric ABS installed on an electric powered sport utility vehicle (SUV) test platform with individual switch reluctance on-board electric motors transferring torque to the each wheel through the single-speed gearbox and half-shaft. The study presents test results of the vehicle braking on inhomogeneous low-friction surface for the case of ABS operation with front electric motors. The performed tests confirm considerable reduction of braking distance and accurate tracking of the reference slip as compared with the vehicle braking without ABS. Hence the pure electric ABS can be considered as an efficient alternative to anti-lock braking systems with friction brakes only.
