Brushless dc ring motor

  • 19-May-2010 03:30 EDT

ThinGap’s TG14090 brushless dc ring motor delivers 122 kW of shaft power, allowing a ducted-fan to generate 600 lb of thrust, depending on the fan blade design. The motor provides a power-to-weight ratio of 6.4 hp/lb, exceeding the aerospace engineering threshold of 5 hp/lb. The advantage is quieter operation for stealth, and less weight, which can be critical for UAV surveillance and close-support tactical applications. The 14-in electric ring motor contains a built-in control and features low thermal load characteristics.
