Drone ESCs & Speed Controllers
Field-oriented control (FOC) and high-rate PWM speed controllers optimized for drone propulsion, regenerative braking, and low-SWaP flight systems.
Multiple US companies design and manufacture electronic speed controllers, from FOC drone modules to high-power industrial motor drives. Castle Creations (Olathe, KS) manufactures ESCs domestically. Integrated motor+ESC units with Blue UAS Framework compliance are available.
