Electrical Motor Starters Guide
A motor starter is a device which is used for turning on an electric motor. The motor starter consists of two basic main parts; a contractor and an overload. The motor starter performs two main functions of switching the electrical connections that powers the motor and also automatically switches off the motor to prevent the motor from any damage if there lays any problem. Single phase starters have two pole contactors and three phase motor starters have three phase pole contactors. The basic working principle of the electric starters is; these devices use an electric signal to power a solenoid which pulls the contacts together by magnetic attractions.
There are various types of electric motor starters depending on the structure of the electric motor to be controlled and their purpose of use and they comprise equipment adapted for the electric motor to be started at each time. Solid state motor starters control the stopping and staring of electrical motors by gated semiconductor devices such as SCRs or other thyristors. Many electrical mechanical motor starters use bimetallic overload elements to protect a motor during startup and while the motor is running.
