Soft Starters

Purchase quality Soft Starter to elevate Industrial Motor Control Systems

Today, electric motors are extremely important for industries as the power of a variety of heavy machinery-from pumps, fans, and compressors to conveyor belt operations. The way an electric motor is started is crucial for its performance, lifetime, and energy efficiency. Conventional motor starters, such as those which operate directly online (DOL) and via star-delta, subject motors to high inrush current and mechanical stress; hence the emergence of soft starters for smooth, dependable, and controlled starting of motors.

Soft starters are used in all industries, from manufacturing to infrastructure, as an energy-efficient means of motor start and stop. This article gives insight into soft starters, their working principles, key features, benefits, applications, and the selection criteria for finding the most suitable soft starter for your application.

Major Operational Advantages of Soft Starters 

Smooth Startup: Unlike conventional motor starters, it provides a very gradual increase in voltage thus resulting in a smooth startup. There is no mechanical stress whatsoever or jerks that can damage the motor.

Acceleration & Deceleration Control: It offers fully adjustable acceleration & deceleration of the motor. Varying the firing angle slowly or quickly can control the acceleration during startup & deceleration during stopping of motor. This is used in an application where startup acceleration needs to be adjusted.

No Power Surges: Since the conventional motor starter allows full voltage across the motor, a huge inrush current starts flowing into the motor that causes a power surge in the circuit. the soft starter limits such current thus preventing the power surges.

Multiple Startups: Some applications require the motor to start and stop multiple times in a small period of time. such motor, if used with a conventional starter, will experience overheating due to high starting current. However, soft starters drastically increase the number of startups for a motor in a specific duration.

Reduction of Overheating: Motor overheating is a very serious problem. It occurs due to the high winding current during its startup. The soft starter allows a very small amount of starting current which prevents the motor from overheating.

Increased Life Span: The soft starter as compared to a conventional starter improves the lifetime of the motor. It is due to the smooth operation and absence of electrical and mechanical stress on the motor.

Less Maintenance: Due to its smooth operation, the induction motor is less likely to have any mechanical faults, which is why it requires less maintenance as opposed to conventional motor starters.

Efficiency: A conventional motor starter supplies full voltage (very high inrush current) to the motor that consumes too much energy. A soft starter significantly reduces it and allows a gradual increase in energy consumption. Also the power switches are controlled using a very low voltage level. It improves the overall efficiency of the motor.

Compact & Small Size: The soft starter has a very compact design that takes up very small space. Unlike other motor starters, it is very small in size.

Low Cost: compared to other starters such as VFD, this sure does cost less.

What are the Real-World Applications of Soft Starters? 

The soft starter is used in industries and is more appropriate to be used for motors that run at a constant speed.

Fans: The huge fans used in industries run at a constant speed. However, they do require startup protection. A soft starter is the best option for fans.

Conveyer belts: The conveyer belts in industries are used for moving objects & they need extra care. The sudden jerks during starting or stopping using conventional starter may misalign the belts, damage the belt due to mechanical stress, and damage the objects placed on it. It requires a smooth starting & stopping offered by a soft starter.

Motors using belt & pulleys: The motor that drives load through belts & pulleys cannot tolerate sudden jerks. It wears a belt that couples it to the load. A soft starter offers a smooth start for such motor applications.

Water or liquid Pump: Any type of pump connected with a motor requires a smooth starting & stopping due to the sudden pressure building inside the pipes. A conventional starter may generate enough pressure at startup to break the line. A soft starter offers a gradual increase in the pressure of such liquid pumps. However, there is no speed control of the pump during normal operation. A VFD is a better choice for variable pump speed.
