Some Basic Information about Magnetic Motor Starter By Yvon Cay

A magnetic motor starter is a set of contacts who is operated by the electromagnetic in order to start and stop the motor load connected. The control circuit that has transitory contact devices attached to the loop of magnetic starter executes the start and stop task.

The following mechanisms make up the three-pole-voltage magnetic motor starter:

• A set of fixed contacts
• A set of impermanent contacts
• Pressure springs
• Solenoid coil
• Stationary electromagnet
• A set of the magnetic shading loop
• Moving armature

A magnetic starter is a full voltage starter designed to give thermal overload as well as under voltage security for collector cage motor and might be remotely operated automatically or through push button post if you are far from the motor. The purpose is to avoid overheating of the motor. The precise gauge of the load in the motor is the current drained by the motor; therefore, it is called an overload device because of its protecting function. If there is excess current drained by the motor, overheating will result.

The principal purpose of the motor magnetic starter is to give thermal overload security; it is not intended to disrupt faulty current A short circuit search must be performed always in order to find out if protection is needed from the faulty current and if something is there is a fault current, a short circuit security must be provided. The holding loop of magnetic starter is intended to fall down every time line voltage goes down below sixty percent of its regular value, thus giving under voltage security to the load or the motor.

It is very essential to keep in mind that magnetic motor starters are contractors who have the accumulation of overloaded relay assemblies that provide operating to overload security into the motor. Selection of thermal load relay is made with the use of manufacturer's table integrated with the magnetic starter. Furthermore, make sure you are aware of the full load current (FLC) of the motor, service factor (SF) of the motor, and ambient temperature wherein the tool is being activated. Thermal elements are generally based on surrounding temperature of forty degrees Centigrade or one hundred four degrees Fahrenheit.

A magnetic motor starter contains three major contacts used most regularly. These contacts generally are open. This arrangement is used in the start of three-phase motors. The three-phase power is being used by almost all institutional, commercial or industrial facilities in the United States of America. In some areas like in upstate New York and some other regions utilize the two-phase, four-phase wire power. In these cases, you may order 4 regularly open contacts intended for the motor magnetic starter. They can be obtainable in several sizes. The smallest items are just about the sizes of relays, and the biggest starters may take up nearly all the space in a room.

The other kinds of specific magnetic motor starters are the reversing motor starters intended for overturning the motors, and the multi-speed motor starters used for multi-speed specialized motors powered by electricity.
