A motor is used to carry out mechanical operations using electrical energy. Automation of the industrial process has increased with the advancement of technology. For mechanisation of the industrial processes, a high number of motors are required and they need to be controlled to make sure that the industrial process occurs properly. A motor control centre is a large enclosure that has the majority of the motor control equipment required by a manufacturing plant.
The motor control centre or MCC makes it possible to plug in control components that can be unplugged if required so that you don’t need to go through the hassle of wiring all the equipment. The motor control system has a bus bar and other equipment that is required to control the motors. There are also different methods for starting the motor. There are many motor operations that a Megatronic low voltage motor control centre carries out. Some of the components that are housed in the centre are bus bar, motor starter, specialised equipment for controlling etc. These components are then placed onto a panel. The bus bar is used to distribute power to all electrical machinery and by using this we can avoid wiring of many components. This contributes to the compactness of the motor control centre and the number of parts that are used in it. The electrical equipment can be connected easily when the bus bar is used and it will help in the troubleshooting of possible issues as well.
The starters in the motor control unit are used to start the motors and they also provide protection from overloading. There are different starters that can be used for this purpose. There are non-reversible and reversible full voltage magnetic starters. The latter can be designed so that it is able to operate AC motors in both directions. There are also electronic soft starters that produce a current limiting soft start. There are experienced designers who are able to customise the motor control centres to the client’s requirements and make sure that all components that are relevant to the manufacturing plant are included. There are two NEMA classes that wiring of a motor control centre falls to such as Class 1 and Class 2. In class 1, there is no provision for wiring between the units by the manufacturer. These are generally used for small projects that have a small number of motors. In Class 2, control wiring is completed between the compartments.
There are also three types of wiring classification for motor control centre wiring called A, B and C. Type A has no terminal blocks and type B is where the connections that exist between all separate compartments are made to the terminal blocks. There is a master terminal block that all the connections are made to in type C. Selecting a motor control centre depends on the structure, types of unit, design of the unit, power systems and the network technology. You can use the latest technology for connecting a motor control centre.
