The gimbal can be divided into horizontal gimbal and omnidirectional gimbal according to its movable function. According to the working voltage, it is divided into AC constant speed gimbal and DC high speed gimbal. According to the load-bearing capacity, it is divided into light load gimbal, medium load gimbal, and heavy load gimbal. According to the load installation method, it is divided into top mounted pan tilt zoom and side mounted pan tilt zoom. According to the usage environment, it is divided into general and special types. Universal type refers to use in non flammable, non corrosive gases or dust. In the atmospheric environment, it can be divided into usage type and outdoor type. The most typical special application is the explosion-proof gimbal.
There are two motors inside the omnidirectional gimbal, which are responsible for the rotation of the gimbal in all directions, including up and down and left and right. The different working voltages also determine the overall working voltage of the gimbal, which generally includes AC 24V, AC 220V, and DC 24V. When receiving the up and down action voltages, the vertical motor rotates and drives the vertical transmission wheel disc to rotate through the gearbox; When receiving the left and right action voltages, the horizontal motor rotates and drives the horizontal gear plate at the bottom of the pan tilt platform to rotate through the gearbox.
It should be noted that the gimbal has horizontal and vertical limit bolts, and the gimbal is limited by two micro switches. When the rotation angle reaches the pre-set limit bolt, the micro switch will cut off the power and the pan tilt stop rotating. The limit device can be located outside the gimbal, with a simple adjustment process, or it can be located inside the gimbal and adjusted through an external adjustment mechanism, with a relatively complex adjustment process. But the sealing performance of the external limit device's gimbal is not as good as that of the built-in limit device's gimbal.
The outdoor gimbal is generally the same as the indoor gimbal, but due to the weight of the outdoor protective cover, the load-bearing capacity of the gimbal must be increased. At the same time, the outdoor environment undergoes significant changes in temperature and is susceptible to erosion from rain or moisture. Therefore, outdoor gimbals are generally designed to be sealed and rainproof. In addition, the outdoor gimbal also has high torque and choke protection circuits to prevent the gimbal from forcibly starting and burning out the motor when it freezes. In harsh low-temperature conditions, a temperature controlled heater can also be installed inside the gimbal.
