    In the beginning of the 20th century, there were three candidate propulsion systems to replace the horse and buggy for personal transportation: steam, electric, and internal combustion engines. There were several reasons why the internal combustion engine won out. One was the invention of the electric starter first put in production in 1912. The driver no longer needed strength to crank the engine. Together with the Bosch ignition, major contributions made to the car business by the electrical engineers were combustion engine and electrical starters. Electric lights followed and then the radio in the 1930-the Motorola. But what really spelled the death of the electric car was the discovery of low-cost petroleum, the ability of oil refiners to crack heavy crude into gasoline, and the development of powerful, efficient engines using custom-made fuels in the 1920s, 1930s, and 1940s. Greatly contributing, of course, was the genius of manufacturers such as Henry Ford, which reduced the cost of making mass-produced automobiles so that many could afford them. The next set of vehicles was a trio of electric, hybrid, and conventional vehicles designed and built to meet the needs of urban commuters. These vehicles also demonstrated that the conventional vehicle had the lowest cost and highest performance and could meet emissions requirements, which in the 1970s was the primary driver.

  • Integrated starter generator

    Various types of electric machines can be considered for an application to integrated starter generator (ISG). Permanent magnet (PM) synchronous machines present interesting performances; nevertheless, it remains difficult to reach a significant constant power zone under good efficiency conditions and power factor. The loss of control of electronics at high-speed operations may lead to high-terminal voltages, which can become dangerous for the whole vehicle. In this study, we examine the main advantages and drawbacks of the induction machine, reluctant, and PM machine. Then we present more precisely the wound rotor synchronous machine (WRSM) performances for ISG applications. All these machines must follow strict rules and specifications (low length, high torque, speed, and efficiency). Different kinds of machines have already been evaluated. View full abstract»

  • Switched reluctance and permanent magnet brushless motors in highly dynamic situations: a comparison in the context of electric brakes

    Electromechanical brake (EMB) systems offer the potential for enhanced vehicle control while simplifying the car assembly as well as recycling process. This article offers a comparison of two motor technologies, switched reluctance (SR) and permanent magnet (PM) brushless, motor in highly dynamic situations, in all four quadrants of their torque-speed operating regions, for an EMB application and also describes the motor designs and their static characteristics, before examining in depth their dynamic behavior, in particular special control adaptations to enable the SR motor to reverse rapidly when needed. A 20% longer SR motor provided overall similar dynamic performance, but only if the SR motor is fitted with a speed limit. A method to choose such a speed limit was developed, and the software algorithm implementation was found to be simple and successful. View full abstract»

  • Fuel starvation

    The most important purpose of this work is to analyze the phenomenon of a fuel starvation of a PEM FC system. The incentive for automotive FC applications is quite different from that for stationary power generation or other applications. The dynamic characteristics of FC must be considered. Experimental results based on a PEMFC (500 W, 40 A) noticeably substantiate that, to employ an FC in dynamic applications, its current or power slope must be limited to improve an FC performance, including its voltage-current curve and lifetime. The use of other kinds of auxiliary power source(s) as depicted in the paper, such as batteries or supercapacitors to cooperate with FC main source, is mandatory for high dynamic applications, particularly for future FCVs.

    Wireless technologies are gaining increased acceptance as a viable technology within the industrial solution space. However, it is important for control system architects to fully understand not only the benefits but also the challenges and limitations of wireless technologies. The complex interrelationships between the various wireless technology characteristics require careful tradeoffs to be made in the design of the solution. This is especially true for applications that need to handle continuous data streams where high capacity is critical to maintain the scalability and reliability of the network. Although still relatively new, mesh networks have proven themselves to have significant advantages in robustness, scalability, and low-power consumption over other wireless technologies for use in industrial monitoring applications. Mesh networks employing PDR address the scalability challenges of wireless sensor networking that can limit implementation in production situations by significantly increasing overall packet-delivery rate and reducing network communication overhead. HC_WSN, an approach that will emerge as the important next trend in the wireless sensor networking industry, can be implemented in addition to PDR techniques and will further support the increasing number of applications that require the wireless sensor network to handle greater amounts of data.

  • Hazardous area lighting, temperature considerations, new protection methods

    This article focuses on the reduction in light output as the lamp ages and the qualities needed for safe lighting. Good lighting design is further challenged when the area is a hazardous area. Because a luminaire is considered an ignition source, it is essential to consider proper temperature and, at the same time, maintain sufficient lighting in hazardous areas. New protection methods and new technologies afford designers new choices and flexibility. The objective of good lighting design for hazardous locations is to sustain longer lumen levels and improve the performance of the lighting system. This article will cite new protection methods and light source technologies and their effect on lighting layouts and illumination levels. View full abstract»

    With the advent of new power system analysis software, a more detailed arc flash (AF) analysis can be performed under various load conditions. These new tools can also evaluate equipment damage, design systems with lower AF, and predict electrical fire locations based on high AF levels. This article demonstrates how AF levels change with available utility mega volt amperes (MVA), additions in connected load, and selection of system components. This article summarizes a detailed analysis of several power systems to illustrate the possible misuses of the "Risk Category Classification Tables" in the Standard for Electrical Safety Requirements for Employee Workplaces, 2004 (NFPA 70E), while pointing toward future improvements of such standards.
