D&H Global Enterprise, LLC, is claiming to have created "a new technology in the field of electric machines", a motor\generator which weighs in at 72 pounds with a 5.7" depth which can generate 415 lb.ft. of torque. They are also claiming low maintenance and no difficult motor controller requirement. These specifications appear to be when the motor is used in conjunction with their Power Electronic Unit, a DC to AC power converter and their PMVCU, or Power Management Vehicle Control Unit. If this is correct, it seems that the motor may use AC power, which would require the controller as mentioned above, as all AC motors must use a controller to change the DC power from the on-board batteries to switching AC power - hence their motor would not need more electronics to give it's high performance than any other AC motor. If they can achieve those specifications with their weight and size claims, then they are certainly on to something. It would be nice to see these claims backed up, and pictures of their products. I have contacted them to see if we can get more information.

"100MPG Hybrid Electric Vehicle Technology a Reality Now"
D&H Global Enterprise, LLC., announces revolutionary technology in a new electric power propulsion system for Hybrid Electric and Electric vehicle capability.
Menomonee Falls, WI (PRWEB) March 9, 2007 -- D&H Global Enterprise, LLC., announces a new electric power propulsion system that delivers higher performing and more reliable Hybrid Electric Vehicles (HEV) with reduced complexity, resulting in lower manufacturing and ownership costs.
The current HEV power propulsion systems on the market utilize many complex and costly electronic circuits for monitoring sensors and control platforms, and are efficient only at relatively low speeds. There is a need for HEV performance equivalent to regular gasoline vehicles, but with better mileage. In response, D&H Global Enterprise presents three patent-pending products, the PMRM™, the PMVCU, and the Power Electronic Unit.
The PMRM™ is a new technology in electric motor/generators that is neither an induction motor or any current motor type in the market. It operates at a very high efficiency, with a wide constant torque to speed ratio, develops a high torque to weight ratio, and generates clean electricity with low space harmonics. An additional benefit is it does not require complicated control circuits to function.
"We are very excited about bringing this technology to the public. Large SUV type HEV's using this system, will consume, for example, 40+ MPG on the highway and 50+ MPG in the city, with the same power and torque performance as similar sized gasoline vehicles. A small sedan sized vehicle can achieve over 100MPG," said Senior Company Member, Debbie Hamedi. Hassan Hamedi, another Senior Member, added "The PMRM™ can revolutionize the HEV industry."
"A car can reach the speed of 130mph before dropping of the torque occurs," said Dr. Al Aawar.
A smart control platform (PMVCU) has been developed by D&H Global Enterprise, LLC., to monitor and improve the performance of the HEV. Fuzzy Logic based algorithms are used to control the power management between the ICE and the EGS in the HEV. D&H Global Enterprise, LLC's, PMVCU operates at optimum performance and achieves smooth operation of both ICE and EGS, which reflects in the increase in the lifetime of the vehicle.
An advancement over existing technology, the Power Electronic Unit generates very low time harmonics, with a low switching frequency, resulting in a flat efficiency above 90% for the whole load range. The three products used together in Hybrid Electric Vehicles reduce gasoline usage, maintenance required, and the overall initial cost of the manufactured vehicle. The result is a more affordable, capable, and robust Hybrid Electric Vehicle that reduces greenhouse gas emissions even further.
