Typical Applications of Motor Soft Starters
1. Water pump: Using the pump control function, the pump water hammer phenomenon caused by fluid flow impact can be reduced when starting and stopping, and the system maintenance cost can be saved.
2. Ball mill: Use voltage slope starting to reduce gear torque wear, reduce maintenance workload, and extend service life.
3. Fan: The solid-state soft starter replaces the traditional starter to reduce belt wear and mechanical impact.
4. Compressor: Using current limiting, smooth starting is achieved and the temperature rise of the motor is reduced.
5. Crusher: Use stall protection and quick protection to avoid mechanical failure and blockage caused by motor overheating and burning. The soft starter uses a three-phase parallel thyristor as a voltage regulator, which is connected between the power supply and the motor stator. Such a circuit is a three-phase fully controlled bridge rectifier circuit.
When the 3-phase soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully turned on. The motor works according to the mechanical characteristics of the rated voltage to achieve a smooth start, reduce the start current, and avoid over-current tripping.
When the motor achieves the rated RPM, the start-up process ends, and the soft starter automatically replaces the thyristor that has completed the task with a bypass contactor to provide the rated voltage for the normal operation of the motor, thereby reducing the heat loss of the thyristor and prolonging the service life of soft starter, enhancing its working efficiency, and preventing the grid from harmonic pollution.
The soft starter also provides a soft stop function. The soft stop is the opposite of the soft start. The voltage gradually decreases and the revolutions gradually drop to zero to avoid the torque impact caused by the free stop.
