The NDAA-compliant Sparrow Series provides lightweight, efficient electric propulsion for small UAVs, combining brushless motors with complementary electronic speed controllers. Manufactured in the United States, the range is ideal for drone OEMs seeking reliable domestic propulsion for new aircraft or upgrades to existing platforms.
Sparrow motors incorporate high-quality winding insulation and efficient ventilation and cooling to enhance reliability and operating life. The portfolio encompasses compact FPV motors through to larger units for multirotor, fixed-wing and VTOL platforms, providing options for surveillance, aerial mapping, inspection and environmental monitoring.
The ESC portfolio converts DC battery power into three-phase AC for sensorless motor control, with PWM commands and additional environmental protection available on selected models.
