Protection and prevention are important factors to keep your commercial and industrial business functioning in order. For this purpose, many devices are utilized to optimize function and protect against and prevent many issues that can prevail in terms of operations. One of such devices is known as a motor starter. This device will give you a reliable and superior solution to such prevailing issues. They are used for a variety of applications and are becoming popular.

Purpose of Motor Starters

As mentioned before, the product's main purpose is to protect. However, this particular tool achieves it in two ways and gives a twofold solution. Typically, motor starters are used to mitigate and avoid or prevent electrical overloading. Electrical overloading is very dangerous and can seriously harm the machinery and the employees working near them. Some of the common reasons include:

  • Electrical surges commonly happen due to weather.
  • Sudden shifts in electrical use may occur with your facility
  • When Undetected electrical complications occur
  • The initial load output of the motor when starting major equipment

A motor will initially offer defense by controlling the electrical output of your gadget or equipment as its starting point of operation. From then on, the starter will begin to protect your system, functioning as a fail-safe. If the electrical output or current becomes more than the safe limit of your starter, the motor starter will immediately deactivate the equipment being protected here. 

Why Should you Use a Motor Starter?

All devices require a security measure of some kind. Whether this implies you want a motor starter, be that as it may, relies totally upon different elements. As a rule, a motor starter is renounced and will utilize a disconnect switch. Anyways, much of the time, a motor starter might be your best, or only choice, requiring a starter.

The elements that oversee this change impressively between applications, however, it very well may be expressed that detach will often be utilized in more modest applications. At the same time, an engine starter offers more "complete" security for bigger applications that require a higher load.

Types of Motor Starters

In industries, various starting techniques are adopted to start an induction motor. Following are the types of starters based upon starting methods and techniques:

Across the Linear Starter

Such starters can directly connect to the motor, and the power line provides full voltage. The motors connected through such starters do not have high voltage to avoid any voltage drop in the power line. They are commonly preferred in applications where motors have low ratings and need to operate in one direction.

Full Voltage Reversing Starter

In this 3-phase induction motor's direction can be reversed between two phases. It consists of two mechanically connected magnetic contactors that help them swap phases for forward and reverse directions. It is preferred in applications where the motor must operate in both directions. 

Multispeed Starter

To vary the speed of an AC motor is important. It is crucial to vary the AC supply frequency. Therefore, such motor starters run the motor at some selected speeds to achieve the application requirements. 

Reduced Voltage Starter

The most well-known kind of beginning procedure is to diminish the voltage at the starting of the motor to lessen the inrush current that could harm the engine's windings and cause an enormous dip in voltage. These starters are utilized for high-rated motors.
