Design Analysis of High Power Density Additively Manufactured Induction Motor

2016-09-20
2016-01-2061
Induction machines (IM) are considered work horse for industrial applications due to their rugged, reliable and inexpensive nature; however, their low power density restricts their use in volume and weight limited environments such as an aerospace, traction and propulsion applications. Given recent advancements in additive manufacturing technologies, this paper presents opportunity to improve power density of induction machines by taking advantage of higher slot fill factor (SFF) (defined as ratio of bare copper area to slot area) is explored. Increase in SFF is achieved by deposition of copper in much more compact way than conventional manufacturing methods of winding in electrical machines. Thus a design tradeoff study for an induction motor with improved SFF is essential to identify and highlight the potentials of IM for high power density applications and is elaborated in this paper.

SAE Manual for Incorporating Pneumatic Springs in Vehicle Suspension Designs

1994-09-01
The extensive and increasing use of pneumatic springs in automotive applications has made it appropriate that this manual be prepared to assist the engineer and the designer in understanding the basic principles and uses of pneumatic springs. This manual provides descriptions of the principles involved in pneumatic spring function along with details of the various configurations of pneumatic spring devices and the unique characteristics of each. Pneumatic spring types have been defined correlating with SAE J511 in the SAE (Oct. 1970) handbook regarding pneumatic spring terminology. Background information tracing the evolution of pneumatic springs has been included, as well as some specific examples of design calculations to serve as a guideline for the designer.

Ultracapacitor Applications

2011-04-15
Energy storage, and in particular electrical storage of energy, has become a very talked about topic in circles ranging from lay persons, in regard to hybrid and battery electric vehicles, to professionals, and certainly by legislators and energy policy makers. This book takes a critical look at the physical storage of electricity in the devices known collectively as electrochemical capacitors and particularly as ultracapacitors. Its 12 chapters cover ultracapacitor and advanced battery topics with an emphasis on a clear understanding of fundamental principles, models and applications. But even to professionals, the distinctions between physical and chemical forms of electric energy storage are unclear and, at times, poorly understood, if at all. The reader will appreciate the case studies from commercial to industrial to automotive applications of not only ultracapacitors, but of these power dense components in combination with energy dense battery technologies.

Lectures of the 32nd International Vienna Motor Symposium

2011-05-05
Proceedings from the 32nd International Vienna Motor Symposium now available through SAE International. One of the most prestigious conferences on engine development in the industry today, the International Vienna Motor Symposium, now in its 32nd year, gathers world renowned experts to discuss the current and future state of motor technology. According to Dr. Hans Peter Lenz, president of the Austrian Society of Automotive Engineers, who opened this year’s conference, markets are now in a better position to understand how internal combustion engines and electrified powertrains can actually complement each other. Presenters offered their input and experience in the development of new technologies enabling higher levels of fuel efficiency and power, longer range and a cleaner way for the mobility industry to move forward. The proceedings, available in two volumes and a CD, contain all the technical papers given during the meeting, both in English and in German.

The Global Market for Automotive Turbochargers: 2015 edition

2015-10-01
Since the last edition of this report in 2013, the demand on automakers has been relentless in terms of improving fuel economy and reducing emissions, thus driving increased sales of forced induction systems. The use of pressure charging techniques has therefore expanded significantly. Recent years have seen the ascendancy of the turbocharger and its use by almost every major global manufacturer.

Automotive Powertrain Sensors: Trends & Forecasts to 2021

2015-01-01
Two major concerns for automotive engineers are how best to maximize fuel economy and to reduce emissions. Powertrain sensors, which measure temperature, pressure, rotational speed and other vehicle performance parameters, are central to both. There is also a trend in the powertrain sensor industry toward higher temperature and electromagnetic compatibility requirements, due largely to the increasing deployment of smaller engines.

Range Extenders for Electric Vehicles Land, Water & Air 2015-2025

2014-10-01
Half the electric vehicle market value lies in larger road vehicles, notably cars, and here the legal restrictions are weaker or non-existent, and range anxiety compels most people to buy hybrids if they go electric at all. Over eight million hybrid cars will be made in 2025, each with a range extender, the additional power source that distinguishes them from pure electric cars. Add to that significant money spent on the same devices in buses, military vehicles, boats and so on and a major new market emerges. Whereas today's range extenders usually consist of little more than off- the- shelf internal combustion engines, these are rapidly being replaced by second- generation range extenders consisting of piston engines designed from scratch for fairly constant load. However, a more radical departure is the third- generation micro turbines and fuel cells that work at constant load.

Future Technology for Hybrid and Pure Electric Cars 2015-2025

2014-11-01
E-cars are oversupplied and changing in all respects but in this frenzy of birth and death the future is being created with hybrid cars rapidly gaining market share. The sales of pure electric cars are likely to take off in the second half of the coming decade as certain technical and cost challenges are resolved. Toyota and Tesla have hugely benefitted from correct market positioning. Yet, Toyota is now betting strongly on fuel- cell hybrids, and Tesla on mainstream pure electric cars. A vicious shakeout of car and battery manufacturers has commenced with the winners expecting a handsome pay-off. IDTechEx finds that the global sales of hybrid and pure electric cars will triple to $178.9 billion in 2024 as they are transformed. For example, components are becoming integrated; the range extender, as an optional extra, breaks down the difference between pure electric and hybrid. Car manufacturers vertically integrate and collaborate, competing with their suppliers.

Electric Motors for Hybrid and Pure Electric Vehicles 2015-2025: Land, Water, Air

2014-11-01
The electric vehicle business will approach a massive $500 billion in 2025 with the traction motors segment capturing over $25 billion. Traction motors propelling land, water and air vehicles along can consist of one inboard motor or - an increasing trend - more than one near the wheels, in the wheels, in the transmission or ganged to get extra power. Complex trends in this industry are explained with this updated report, and future winning suppliers are identified alongside market forecasts. The information is especially important as hybrid vehicles may have the electric motor near the conventional engine or its exhaust, and this may mean they need to tolerate temperatures never before encountered in pure electric vehicles. Motors for highly price-sensitive markets such as electric bikes, scooters, e-rickshaws and micro EVs avoid the price hikes of neodymium and other rare earths in the magnets.

Electric Vehicle Forecasts, Trends and Opportunities 2015-2025

2014-10-01
This master report summarizing and forecasting every sector of the EV industry remains unique. It adds new sectors as they become substantial, the latest being car-like micro-EVs homologated as quadricycles in Europe. Many profitable niches are emerging just as the largest major sectors are changing in importance; the industrial and commercial sector is now bigger and much more profitable than e-cars, and is set to remain so for at least eight more years. All components are changing with supercapacitors sometimes replacing or partly replacing batteries and also new types of battery, energy harvesting, power electronics and structure powering growth. Disruptive change is now the norm and the fruits of all this are truly spectacular; including such things as the Marian fast- surface boat that acts as a submarine when necessary, the fixed-wing plane that will stay aloft for five years on sunshine and the flying jet ski.
