DC motors provide operational efficiencies in excess of 90%

Maximising battery life can be a decisive factor to many mission-critical systems where longevity of the equipment can affect the outcome. Increasing the life of any battery-operated system has become a key initiative for equipment manufacturers, with BEI Kimco Magnetics meeting this initiative with the introduction of frameless Brushless DC Motors in multiple designs.

The motors 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 a customer's existing assembly, minimizing the need for extra components and reducing overall weight.

"OEMs developing equipment that rely on batteries will find these motors extremely valuable in extending their product's range or service life without frequent battery charges or replacement," says Walter Smith, Applications Engineer/Project Manager for BEI Kimco. "Whether it is a remotely powered IED robot that needs long distance range, or a motorized medical instrument that needs untethered flexibility, customers want to get the most out of their batteries to maximize product efficiency."
