A low-voltage power generation platform developed by Kollmorgen Corp. combines system efficiency with reduced package space to meet the needs of today’s military vehicles. Consisting of flexible power electronics that support multiple vehicle motor/generator configurations and mild hybrid capability, the platform is uniquely capable of generating onboard vehicle power at the voltage and power levels demanded by today’s military vehicles. Kollmorgen Corp. has retained American Business Development Group (ABDG) to help bring the company’s new Power Generation System to the Defense market.
The combination of Kollmorgen’s system efficiency (industry-leading at 90%+) and reduced package space results in dramatic fuel and weight savings for the vehicle. The low-voltage platform can be configured as an integrated starter generator (ISG), air-cooled belt-driven motor/generator, or PTO-driven system providing ranges of power from 10 kW up to 50 kW, all at 28 Vdc. The system is rooted in mature technology backed by more than 70 years of motion control and power generation expertise, and has the flexibility to support demanding defense vehicle power needs within a small space, at low or high voltage, ac, dc or both.
Military Personnel Safety a Priority
“Combining Kollmorgen’s power generation and motion control design and development experience with ABDG’s process knowledge of the track and wheeled vehicle fleet within the DOD [Dept. of Defense] will help improve military personnel safety by enabling and helping to facilitate the design and deployment of lighter and significantly more fuel-efficient defense vehicles,” says Bill Skipper, ABDG president and CEO. “This opportunity will be led from ABDG’s Detroit office where we have more than 150 years of combined experience in the Tank and Automotive Command [TACOM] and OEM community.”
Kollmorgen’s inline variant of the low-voltage Power Generation System has been integrated into the Fuel-Efficient Ground Vehicle Demonstrator (FED), a U.S. Army Tank Automotive Research Development and Engineering Center project. The Kollmorgen system enables the FED Alpha vehicle to provide 30 kW of power at 28 Vdc, over a wide engine operating range. When compared to other high-voltage power generation systems available for the FED, the Kollmorgen low-voltage ISG solution reduced vehicle weight by 150 lb.
“With the Power Generation System, Kollmorgen can provide the power that OEMs need at the voltage they want. And unlike vendors who supply just high- or low-voltage systems, we are uniquely positioned to serve as a one-stop shop for heavy-duty vehicle OEMs who have a wide variety of power needs within a single vehicle, and/or across vehicle platforms,” says Brandon Edlefsen, director of Kollmorgen’s Vehicle Electric Power Business Unit. “As application demands evolve, defense vehicle OEMs adjust their designs and need to find the optimum voltage to deliver the desired power, so working with a single supplier who can deliver low- or high-voltage solutions, or anything in between, is a huge advantage.”
