Electric drones, remotely operated vehicles, and autonomous vehicles offer superiorities over conventional fossil fuel, including reductions in carbon footprint, noise, and emissions. As a result, the number of electric vehicles is growing, from military and commercial to industrial. Other products use batteries as a main or auxiliary power source, for example electric robotics and medical equipment.
Maximizing battery life can be a determining factor in mission-critical systems. For instance, in battery powered medical devices or remotely driving military vehicles, the ability to the last 13 minutes instead of 10, can make a statistical difference. Increasing the life of any battery operated system has become a key step for developers.
Frameless Brushless DC Motors in multiple designs deliver operational efficiencies over 90%, enabling extended battery life. For battery dependent applications, motor efficiency is paramount in getting the longest operating me before it needs to be charged.
The High Torque Density Brushless DC Motors achieve this efficiency through improved weight and envelope profiles. Part of the efficiency is based on the use of proprietary low magnetic circuit design techniques. Other important features include a frameless motor design composed of two pieces — a rotor and stator. This design is easy to integrate into an existing assembly, minimizing the need for additional components and reducing overall weight.
