The motor starter is electrical equipment that starts or stops an electrical motor, protect it in-lieu of electrical fluctuations, and may also reverse its functioning. The starter protects a motor through mitigating the effects of electrical overloading. Electrical overloading can cause serious damage to the motor and is also a threat to the health of the employees and other assets that may be located around a motor. Electrical fluctuations, weather-related electrical surges, greater initial electricity load, and even electrical complications may cause an accident or damage the motor. The electrical motor is a fail-safe device that gets deactivated automatically when the flow of current is greater than the safe limit. As the name suggests and said earlier, the electrical starter also controls the inflow of electric current, when the electric motor starts initially.
The two main components of an electric starter
The two major building blocks or components of an electric starter include:
Overload protection: The component of motor starters does not allow the motor to draw excessive current and suffer from burnouts. This component also prevents the overheating of the motor.
Contractors: The electric current that reaches to the motor is controlled by the contractor. They act continuously to interrupt and to establish the power circuit in a way that no harm to the motor is caused.
The two major types of motor starters
The Manual Motor Starter
The manual motor starter is a technologically lesser advanced model of electric starters. As it is operated manually, there are no complications involved. The starter can be easily switched off or on by pressing the button which is mounted on the top of the starter. The starter is connected to the main motor. The manual motor starters offer advantages including lesser cost, availability of enclosures, smaller physical size, greater overload protection, economical and safe operation and others.
Manual Motors may not provide protection against low voltage, which may occur when a power failure occurs and the equipment starts after the electricity is resumed. A dangerous situation may occur as the starter will start automatically once the power gets restored. Therefore the manual starters can only be used for controlling and starting motor that operates on a smaller load, and where voltage related protection is not required.
The AC Magnetic Motor Starter
The AC magnetic motor starters are the more technologically advanced version of electric motors. The magnetic water is also offered other features like automatic and remote operation, and hence an operator does not need to be designated for operating the motor.
Motor starters and motor control panels are available today in various designs and with a number of features. In order to make the best pick, you need to talk to a leading and reputed motor starter agency and provider. A brief consultation will help you know more about the motors and which one is the most suitable for your motor and process.
Electrical motor starters are very useful and can provide for the greater service life of a motor. They are also beneficial towards preventing accidents and ensuring the safety of men and material around. Available in different sizes, forms, and with varying features, an electrical motor should be procured in-lieu of the process, motor, and other considerations.
