Yankee Scientific, Incorporated, has developed and demonstrated the first diesel fueled refrigerator that maintained acceptable temperatures in the freezer and refrigerator compartments for one month without external power and with little or no maintenance. This innovation has immediate military and civilian applications including refrigeration in field kitchens, equipment cooling, and potential thermoelectric generators for remote communications devices.

Turning vehicles into generators

AuraGen power system moves from military to commercial to heavy-duty markets; up to 8.5 kW off a vehicle engine
Starting with basic magnetic technology that was originally developed for military applications, Aura Systems, Inc. has taken that technology and expanded and developed it to produce a system that allows almost any type of mobile equipment to become a rolling generator set. The AuraGen, from Aura Systems, is in commercial production and the company has recently begun expanding the use of this unique mobile electrical generation system into broader and more heavy-duty markets.
Using an induction generator, the AuraGen system is usually a belt driven unit off a vehicle's engine. The current models can produce up to 8.5 kW of continuous, highly-regulated clean 120/240 va.c. power, according to Keith Stuart, director of applications development. An optional battery charger can provide 200 amps of 14 vd.c. power at the same time.
Further, the El Segundo, Calif., manufacturer has recently added a new inverter option that can continue to provide a.c. power from a battery pack when the engine is not operating and then is automatically recharged when the engine runs.
The military version of the 120 Va.c./28 Vd.c. AuraGen generator is being used on the VIPER version of the Army's High Mobility Multipurpose Wheeled vehicle (HMMWV), the well-known Humvee, or Hummer as it is known in the commercial markets. On the Humvee, as well as a number of other lighter duty military vehicles, the AuraGen can be used as a source of auxiliary power. Humvee configurations include use as an ambulance, TOW missile system carrier, shelter carrier, as the platform for a new radio digital terminal, and the pedestal-mounted Stinger missile system. All of those systems require a significant amount of auxiliary power.
Outside of its military uses, the AuraGen system has moved into the commercial and specialty vehicle markets on a variety of gasoline-powered vehicles, though its most popular system has been installed on Ford F/E series trucks with the 7.3 L Power Stroke diesel. Applications include utility-industry bucket trucks, ambulances, law enforcement vehicles, fleet service vehicles, radio/TV broadcast trucks, fire trucks, telecom and food services vehicles. Like the military, these are all applications with a need for additional on-board electrical power, mostly for auxiliary devices.
The AuraGen system has also begun to find applications in the recreational vehicle market and the company has recently started to look at the heavy-duty on-highway and off-highway vehicle markets, as well as possible marine uses.
Two versions of the AuraGen are currently available, a 5 kW and an 8.5 kW system. A 10 kW package is in the works and a 20 kW system is possibly on the horizon. The 5 kW system requires about 10 hp from the engine to generate the rated power levels, Stuart said, while the 8 kW unit draws 16 hp from the engine.
The AuraGen system is sold as a turnkey, fully integrated power system, tailored specifically for an individual vehicle application. The heart of the system is the patented induction generator, weighing 62 lb. (65 lb. for the 8.5 kW model), that looks like a cross between an alternator and a pancake-type generator.
Measuring 12.16 in. in diameter and 5.085 in. across, the induction generator is generally mounted on the front of the engine and usually requires relocation, or in some cases, replacement of the alternator. Fitting the AuraGen to an existing vehicle usually takes about eight hours, the company said.
The AuraGen power unit is an axial gap induction design with a solid steel structure in the rotor that acts as the magnetic element and which is specifically designed to enhance rotor conductivity.
The other major component of the system is the electronic control unit (ECU) that weighs 52 lb. and is weatherproofed so that it can be mounted in virtually any location on a vehicle. The ECU includes a micro-processor, a 400 Vd.c. bus, a vector controller and two-phase inverter.
The processor receives input from speed and thermal sensors and draws about 3 amps maximum from the vehicle battery to power up the logic circuits and power the ECU cooling fans. A small control panel, typically located in the cab of the truck, is used to turn the generator on and off The AuraGen system also includes an engine idle control that is typically mounted on the engine compartment firewall.
Aura has also developed a line of brackets to mount the power unit to various engines. Stuart said brackets are currently available for over 90 different types of vehicles, with more versions being developed for new applications.
For "plug-in" power uses, the electrical power developed by the system can also be delivered to optional 120/240 Va.c. outlets that are mounted on the vehicle, with a remote 120/240 Va.c. power strip also available.
While almost all of the AuraGen systems in operation are directly driven off the engine, the company also offers a by draulically driven package. The hydraulic drive package is provided with mounting brackets designed to fit onto 9 in. frame mils and requires a 10.8 gpm flow at 2200 psi for 5 kW operation.
A PTO driven system is also offered that works with both "hot shift" and manually engaged PTOs. Aura said that with a 1.25:1 PTO, the system can generate full power at under 1000 rpm. This version is designed to mount under the chassis and includes a sheet metal enclosure.
With electrical generation today being as much about power quality as gener-ation, Stuart said the AuraGen has a pure sine wave output and produces 60 Hz power at [+ or -]0.16 Hz, 120 V at [+ or -] 2 percent and 2.1 percent total harmonic distortion (THD). The latter is especially important, he said, in that it allows the system to power more sophisticated electronics such as computers, as well as producing flicker-free lighting.
Stuart added that the system has a power reserve of 7.5 kW for three seconds for the 5 kW unit and 9 kW for the 8.5 kW model, which allows the system to start a variety of tools, especially compressors, without shutting down.
One of the keys to AuraGen is that it has virtually no mainte nance, as there are no wear/contact points except the bearings. Further, balanced magnetic fields on both sides of the rotor are designed to reduce bearing side load, the company said. The system is also manufactured without using exotic materials, and uses off-the-shelf electronic components and off-the-shelf automotive parts.
While Aura has just started to look at the heavy-duty markets for the system, there would seem to be more than a few potential applications off-highway Aerial lifts, railroad maintenance equipment, along with agricultural tractors and combines come to mind. It would also seem that many construction fleets would welcome 5 or 10 kW of electrical power roaming about a job site.
For the on-highway marker ambulances, telecom trucks and such are obvious candidates, as are larger Class 7 or 8 trucks, which are continually looking for more power to operate sleepers and other on-board electronics.
Maybe the most intriguing market is marine. The power needs of pleasure or small commercial boats are the same as most other types of engine-powered equipment, but are also among the most constrained in terms of available space. Adding the capability to generate 5 or 10 or 20 kW without increasing the size of the engine compartment would seem to be an idea that could be well received.
One future use might involve diesel exhaust aftertreatment. One of the problems with some regenerative catalysts is that there is not enough power (or heat) to effectively "light off" the catalyst. Having an additional source of power that does not significantly affect vehicle performance, might provide part of the answer.
In expanding into the heavy-duty markets, Aura Systems has recently signed a quartet of Detroit Diesel engine distributors; Inland Detroit Diesel; Williams Detroit Diesel--Allison; Western Branch Diesel Inc.--Detroit Diesel Allison; and Stewart & Stevenson.
