The principle of the camera stabilization using brushless direct drive motors, In fact, gimbal based on BLDC motors is very similar to regular gimbal based on hobby servo. Features Sealed Case to prevent contamination by dust and dirt. Hollow shaft for slipring Configuration:24N28P,provide more torque.
