AC motors draw 7 times the rated current when starting. This high current causes damage to the motor wiring, electrical and mechanical equipment.In the past, triangle star switches were used to reduce the starting current, but this method is also not suitable for large electric motors or high sensitive loads because it reduces the current in only two steps.Today, soft starters are widely used in various industries to start electric motors. Soft stars This equipment contributes to the useful life of the device by optimizing the starter current, which would cause a lot of shock to the engine during normal start-up. control the starting current linearly and with the desired slope and increase the life of the device by preventing electric shock from entering the motor.Soft starters are equipped with highly advanced software so that any desired application can be achieved by the software program.Also, soft starters are equipped with all the protections required by the electric motor and are also equipped with a bypass contractor to remove all electronic systems from the circuit after the engine is fully started and power the motor through the bypass contractor circuit.Also, soft starters are equipped with all the protections required by the electric motor and are also equipped with a bypass contractor to remove all electronic systems from the circuit after the engine is fully started and power the motor through the bypass contractor circuit.
Advantages of using soft starters:
1) Reduction of starting current and less electric shock on the motor and network
2) Ability to plan how to set up with the desired slope
3) Reduce damage to electrical and mechanical systems
4) Increase the life of equipment
5) Reduce energy consumption
6) Increase productivity
