Gimbal Motor Encoder Systems Gimbal Motor Encoders: What Are Encoders for Gimbals? Gimbals are pivoted support systems that allow objects to rotate around one or more axes. They are used on mobile platforms such as ships and drones, and are essential in helping stabilized cameras and other video capturing devices move from left to right, upwards, and downwards over a partial or full 360-degree rotation. Encoders installed on the gimbal axes provide information about the camera orientation relative to the platform. Encoder-Based vs. Non-Encoder Gimbal Systems Short focal length camera mounts can function regularly without encoders. For medium to long focal length cameras, encoders for gimbal motors are essential. The main advantage of a non-encoder gimbal system is its mechanical and electronic simplicity. But this is only applicable to individual consumer use. Netzer’s Electric Encoders™ offer a combination of the best features of encoders with optical or magnetic sensors. While making use of advanced technology, the Electric Encoders™ are simple to use, durable, and robust having virtually no failure- mechanism. Netzer Electric Encoders™ feature high customizability, high-speed options, a wide range of diameters, low-profile design, low power consumption and several communication protocols – making them beneficial to many possible applications. Benefits of Encoders for Gimbal Systems If installed and used properly, encoders for gimbal systems can provide a very smooth return after disturbance. Motors will not skip steps and the movement area of the axis can be significant with encoders. When on follow mode, there will be no yaw drifting. Plus, the gimbal’s motion can be precisely referenced to the system’s frame. Encoders alone do not provide inertial stabilization — that is the role of gyroscopes or rate sensors. Likewise, they cannot compensate for mechanical limitations such as structural compliance. For optimal performance, a gimbal system must pair precision encoders with a solid mechanical design. Let us know how we can improve your gimbal system even further with precision Netzer products. Do you want to know which absolute rotary encoder best suits your application?
