Structure of motor control cabinet
The motor control cabinet consists of two parts: control circuit and power circuit. Among them, the control circuit mainly includes components such as controllers, contactors, relays, buttons, indicator lights, etc. These components can achieve functions such as starting, stopping, turning, and speed control of the motor. The power circuit mainly serves to supply power to the control circuit, including circuit breakers, wiring terminals, power relays, etc.
The main uses of the motor soft start control cabinet include:
1. Reduce the starting current of the motor, thereby reducing the distribution capacity and avoiding unnecessary investment in capacity expansion.
2. Reduce starting stress, which helps to extend the service life of electric motors and related equipment.
3. By smoothly starting and soft stopping, the surge problem that may be caused by traditional starting equipment is avoided.
4. It has a light load energy-saving function, which can automatically reduce the operating speed of the motor when it is under light load, thereby improving energy efficiency.
5. Provide multiple protection functions, such as overcurrent, overvoltage, overheating, etc., to ensure the safe operation of the motor and related equipment.
6. Adjust parameters based on load characteristics, such as current limiting values and starting time.
