[0002] With the rapid development of the economy, the demand for motors is increasing, and their scope of use is also expanding. Among them, stage lighting equipment has added a lot of motion control to meet some needs, and the key components of these controls, such as horizontal and vertical rotation drive motors, tend to use three-phase motors.

[0003] However, as stage lighting equipment has become increasingly sophisticated, the space available for motor placement has shrunk, resulting in limited installation space. However, the original waterproof terminal blocks on the motor's exterior are large, making it difficult to properly accommodate the motor. Furthermore, this design typically requires conventional cables, and most users accustomedly lift the motor by pulling on the cable. This method of lifting the motor can easily pull out the fragile cable, leading to poor wiring of the motor's internal components and malfunctioning of the motor.

[0004] At the same time, in a stage environment, lighting equipment needs to run for a long time and may be exposed to various environments, including accidental splashing of rain, other liquids or solvents. If the lighting equipment installed on the top of the stage is accidentally splashed with rain, other liquids or solvents, it may cause water to enter the motor of its motion control, which may easily cause the internal parts of the motor to corrode, causing malfunctions and making it impossible to work normally. Utility Model Content
