Electrically powered unmanned aerial vehicles, remotely operated vehicles, and autonomous vehicles offer advantages over conventional fossil fuel, including reduced carbon footprint, noise, and emissions. Thus, the number of electric vehicles is growing in industries ranging from military and commercial to industrial. Other products use batteries as a primary or auxiliary power source, such as motorized robotics and medical equipment.
Maximizing battery life can be a decisive factor in mission-critical systems. For example, in battery operated medical devices or 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 developers.
Frameless Brushless DC Motors in multiple designs deliver operational efficiencies in excess of 90%, enabling extended battery life. For battery dependent applications, motor efficiency is paramount in getting the longest operating time 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 using 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 extra components and reducing overall weight.
Brushless DC motors range up to 20 in. in O.D. with torques in excess of 50 Nm and operational speeds beyond 70 K rpm.
