How to Find the Best Soft Starter for Your Facility

Teknologi.id - A soft starter is a type of motor starter that reduces the voltage during the motor's startup using a voltage reduction approach. During motor startup, the soft starter provides a progressive increase in voltage.

The engine gradually accelerates and gains speed in a steady manner because of this. It prevents mechanical tearing and jerking caused by unexpected full-voltage supply. An induction motor's torque is proportional to the square of the current. The current is proportional to the supply voltage. As a result, the starting torque can be controlled by the supply voltage.

In a traditional motor starter, supplying full voltage to the motor produces maximum starting torque, posing a mechanical risk to the motor. As a result, a soft starter is a mechanism that minimizes the starting torque and gradually increases it until it reaches its specified speed in a safe manner. The soft starter restores the full voltage supply via the motor once it reaches its rated speed.

Benefits of Soft Starter

• Smooth Startup: Unlike traditional motor starters, it gives a steady increase in voltage and, consequently, speeds, resulting in a very smooth start. There is no mechanical stress or jerks that could cause the motor to fail.
• Acceleration and Deceleration Control: The motor's acceleration and deceleration are fully controllable. The acceleration during motor initiation and deceleration during motor stopping can be controlled by varying the firing angle slowly or fast. This is utilized when the starting acceleration of an application needs to be changed.
• No Power Surges: Because a traditional motor starter allows the full voltage across the motor, a large inrush current flows into the motor, causing a power surge in the circuit. The soft starter regulates the current and thereby prevents power surges.
• Multiple Startups: Some applications necessitate the motor starting and stopping several times in a short period of time. When utilized with a standard starter, such a motor will overheat due to the high starting current. Soft starters, on the other hand, dramatically enhance the number of times a motor may start in each amount of time.
• Reduce Overheating: Overheating in motors is a severe concern. It happens as a result of the high winding current during initiation. The soft starter allows for a very low amount of starting current, preventing the motor from overheating.

Applications of Soft Starter

The soft starter is commonly used in industries and is best suited for motors that run at a consistent pace.

• Fans: In industries, large fans run at a constant pace. They do, however, require starting protection. For such enthusiasts, a gentle beginning is a perfect solution.
• Conveyor belts: Conveyor belts are used in industries to transport things and require special attention. The rapid shocks that occur when utilizing a typical starter might cause the belts to misalign, damage the belt due to mechanical stress, and harm the things that are placed on it. It necessitates the use of a soft starter for smooth starting and stopping.
• Motors that use belts and pulleys: Motors that use belts and pulleys to drive loads cannot withstand unexpected jerks. The belt that connects it to the load is worn by it. For such motor applications, a soft starter ensures a smooth start.
• Water Pump: Due to the abrupt pressure accumulating inside the pipes, any form of pump coupled to a motor requires a smooth beginning and stopping. Initially, a traditional starter may generate enough pressure to break the line. Such liquid pumps benefit from a gentle starter, which gradually increases the pressure. During normal operation, however, the pump has no speed control. For variable pump speed, a VFD is a superior option.
  

Make the Best Choice for Soft Starter

Voltage management is significant for motor operation. Therefore, choosing the right equipment is of utmost importance. Finding a supplier that offers top-quality soft starters can be very useful. Therefore, when choosing a supplier, it is best to first do in-depth research. When you find the right firm, ensure that you reach out to them to explain your requirement.
