Introduction to the Operating Principle and Advantages of the Stage Electric Hoist Controller Operating Principle Signal Input The stage electric hoist controller is usually equipped with a push - button or joystick - type operation interface. When an operator presses buttons such as up, down, left - right movement (if it has horizontal movement function), the controller receives corresponding electrical signal commands. For example, when the "up" button is pressed, the button switch closes, the circuit conducts, and an electrical signal representing the up - movement command is generated. Signal Processing and Transmission The microprocessor or control circuit inside the controller identifies and processes the input signals. It converts the operator's commands into a specific control signal format, and then transmits these signals to the motor driver of the electric hoist through wires or a wireless transmission module. In wired transmission, the signals are transmitted through shielded cables to reduce external interference. In wireless transmission, radio - frequency technology is used, such as common Bluetooth, Wi - Fi, or dedicated wireless frequency bands, to achieve remote signal transmission. Motor Drive and Control After receiving the signals from the controller, the motor driver adjusts the current and voltage output to the motor according to the type and intensity of the signals. For an AC motor, the driver may control the speed and rotation direction of the motor by changing parameters such as the frequency and phase of the power supply. For instance, to make the electric hoist rise, the driver outputs appropriate current and voltage to drive the motor to rotate forward, driving the wire rope drum to wind the rope and lift the heavy object. Conversely, to lower it, the driver drives the motor to rotate in reverse, releasing the rope to lower the heavy object. For a DC motor, the driver controls the operation of the motor by adjusting the magnitude and polarity of the output DC voltage. Feedback and Adjustment To ensure the precise operation of the electric hoist, some advanced controllers also receive feedback signals from various sensors on the electric hoist. For example, a weight sensor monitors the load weight in real - time to prevent over - load operation. A limit sensor detects the upper and lower limit positions of the hook. When the hook reaches the limit position, the sensor sends a signal to the controller, and the controller immediately cuts off the motor power to avoid dangerous situations such as over - running or hook - dropping. The controller adjusts the operating state of the motor in real - time according to these feedback signals to ensure the safety and accuracy of the operation. Advantages Precise Control The controller can achieve precise control of the stage electric hoist, and can accurately adjust parameters such as lifting speed and position. In stage performances, the positioning requirements for lighting, scenery, and other equipment are extremely high. The controller can ensure that the equipment reaches the designated position accurately, creating a perfect stage effect. For example, in a ballet performance, a delicate crystal chandelier needs to be slowly and precisely lowered to a specific height above the stage. This can be easily achieved through the precise control of the controller. Convenient Operation Whether it is a wired or wireless controller, its operation interface is designed to be simple and easy to understand. Operators can master it proficiently with simple training. The wireless controller also allows operators to move freely within a certain range, flexibly control the electric hoist, and is not limited by the length of the cable, which is convenient for operation in a complex stage environment. For example, in different corners of a large - scale stage, workers can easily control the electric hoist to lift and transport props through the wireless controller. Multiple Control Modes Many stage electric hoist controllers have multiple control modes, such as jog mode and continuous operation mode. The jog mode is suitable for fine - tuning the position of the equipment, while the continuous operation mode can be used to quickly lift or lower heavy objects to meet the operation requirements in different scenarios. In the initial stage of stage scene construction, large - scale scenery may need to be quickly lifted and transported, and the continuous operation mode can be used to improve efficiency. While during the performance, when making fine adjustments to the position of the props, the jog mode is more appropriate. High Safety Performance The controller integrates multiple safety protection functions. In addition to the overload protection and limit protection mentioned above, it may also have functions such as leakage protection and short - circuit protection. When an abnormal situation is detected, the controller can quickly cut off the power supply to protect the safety of equipment and personnel. In a stage where there are a large number of people, the safety performance of the controller is of great importance, effectively avoiding safety accidents caused by equipment failures. Compatibility and Expandability

Modern stage electric hoist controllers usually have good compatibility and can be integrated with other control systems on the stage (such as lighting control systems, audio control systems, etc.) to achieve the coordinated operation of the entire stage equipment. At the same time, it also has certain expandability, which is convenient for subsequent upgrades or adding new functional modules. For example, by adding a communication module, the controller can be connected to the central stage control system to achieve remote centralized control.
