GM3506 Gimbal Motor w/Encoder


What's encoder technology in brushless gimbal control system?

The 3 axis stabilization gimbal system that relies on both active motor-driven components and passive inertial stabilization. Passive stabilization relies on the principles of inertia (tendency of an object to resist change in its motion) and requires that the camera is well-balanced in the Pan, Tilt, and Roll Axes. Active stabilization refers to the techniques of using sensors to measure the camera’s Pan, Tilt, and Roll movements and counteract those movements using motors attached to the 3 axes.


Easy to do gimbal tuning, no need to do much calibration work any more.

Power saving, 5 times long working time than gimbal without encoder system.

Twin IMUs.

Faster response, motor torque increasing instantly, no bug for difficult rotating angle any more.

Encoder chip AS5048A

GM3506 Gimbal motor with Encoder AS5048A

The GM35 series motor by iPower Motors is the ultimate brushless gimbal motor for SLR and similar weight Cameras. This motor is designed for large-scale multi-rotor platforms looking to lift SLR sized gear – 1.5KG/cm Torque. 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.

Encoders are special sensors that are added to each brushless motor of a Gimbal Stabilizer allowing the system to more accurately track motor position for increased stability which in turn also increases battery efficiency.
