Overview
The iFlight GM2804 Encoder Combo Set is a brushless gimbal encoder system designed to improve motor position tracking in a 3-axis stabilization gimbal, helping increase stability and battery efficiency. In a gimbal control system, passive inertial stabilization depends on proper camera balance across pan/tilt/roll axes, while active stabilization uses sensors to measure movement and drive motors on the three axes to counteract that movement.
Key Features
- Easier gimbal tuning with reduced calibration work
- Power saving: up to 5x longer working time than a gimbal without an encoder system (as stated)
- One IMU (as stated)
- Faster response with instant motor torque increase for difficult rotating angles (as stated)
- Encoder chip: AS5048A / A5048a (as stated)
