Raser Technologies, a technology licensing company established to develop and license advanced electric motor, controller and related technologies, announced that it plans to unveil a new more powerful electric motor design for electric and hybrid-electric vehicles next week at the 22nd Electric Vehicle Symposium (EVS-22) held October 23-28, 2006 in Yokohama, Japan.
Raser will announce a new 100kW AC induction-based electric motor design called the Symetron P-100. The P-100 was designed to double the performance of the company’s award-winning P-50 integrated starter alternator. (Earlier post.)
The Symetron P-100 is one in a series of high-horsepower motor designs Raser is developing to meet the demand for more onboard electric horsepower required by the next generation of strong hybrids, plug-in hybrids and fuel cell vehicles. These vehicles are more electrically dominant than today’s mild hybrids and often require the electric motor to serve as the primary drive for the vehicle.
The electric motors used in today’s mild hybrid vehicles typically deliver 15-20kW of power utilizing permanent-magnet synchronous motors (PMSMs) that require expensive rare-earth magnets to operate. Permanent magnet motors generally become even more expensive as the motors get larger.
Raser’s AC induction-based technology, recently awarded the Drive System Technology Innovation of the Year Award by Frost & Sullivan, achieves its high performance through advancements in motor control software and motor design, without requiring the use of permanent magnets. The Raser motor design offers performance and form factors comparable to PMSM-based systems, but provides the economy and reliability of the AC induction-based platform. This cost-effective alternative may help automakers reduce costs and improve reliability to bring next-generation hybrids more within reach of mainstream consumers, according to the company.
In addition to unveiling the new motor design, Raser will exhibit other new implementations of its Symetron family of technologies, including its new high-output, high-efficiency brushless alternator technology, designed to improve performance and fuel economy in conventional vehicles and its award winning P-50 integrated starter alternator.
