July 31, 2014 - Maximizing battery life can be a decisive factor to many mission-critical systems where longevity of the equipment can affect the outcome. For example, in battery operated, remotely piloted military vehicles, the ability to last 13 minutes instead of 10, can make a significant difference. Increasing the life of any battery-operated system has become a key initiative for equipment manufacturers. 

To meet this market initiative, BEI Kimco Magnetics has developed new frameless Brushless DC Motors in multiple designs that provide extremely high operational efficiencies in excess of 90% that enable extended battery life. For battery dependent applications, motor efficiency is paramount in getting the longest operating time before it needs to be charged.
The newly designed High Torque Density Brushless DC Motors are able to achieve this superior 90% plus efficiency with improved weight and envelope profiles. Leveraging BEI Kimco's 40 years of expertise in advanced motion component design, these high efficiency motors were realized by utilizing proprietary low magnetic circuit design techniques. Other important features include a frameless motor design composed of two pieces - a rotor and stator. This design makes it easy to integrate into an existing assembly, minimizing the need for extra components and reducing overall weight.
BEI Kimco Magnetics designs and manufactures custom fractional horsepower permanent magnet brushless DC Motors. The brand is on the leading edge of manufacturing process technologies and possesses the material selection expertise required to achieve the highest torque densities available in the industry. Motors range up to 20" in O.D. with torques in excess of 50Nm and operational speeds beyond 70K rpm.
