Motor Control Centers- MCCs


Motor Control Centers- MCCs

Motors are critical assets as well as large consumers of electrical energy, accounting for 60% of all electrical energy consumed in industrial businesses. A strong, tested, and validated architectural approach to motor management unleashes greater safety and performance for your motors, allowing for advanced asset management and energy efficiency.

Each motor controller in an MCC can be specified with a variety of options such as separate control transformers, pilot lamps, control switches, extra control terminal blocks, various types of thermal or solid-state overload protection relays, or various classes of power fuses or circuit breakers.

A motor control center can be supplied ready to connect all field wiring by the customer, or it can be an engineered assembly with internal control and interlocking wiring to a central control terminal panel board, programmable controller, or circuit breakers.

Almost all electrical machines have their own control system. Motor controllers can differ depending on the functions that these devices perform. When an easy switch is used to connect a motor to an electric outlet, it is frequently a simple flip switch button or knob.

Simple switches are usually operated by hand; however, a sensor connected to contacts or relays can serve as an auto start/stop for the motor. Another switch may provide additional options for selecting specific motor connections. This can include the voltage control, multiple speed, and reverse rotation control during startup.
A smart device in the MCC consists of intelligent devices such as a current module, voltage module, and its controller, which collects motor operating data and transmits it to a PLC or process control system.

Overload, overcurrent, instantaneous overcurrent, locked rotor fault, and phase failure are all reported immediately to the PLC that is linked to the MCC intelligent device. As a result, the security is both quick and reliable.

Furthermore, the PLC can be used to remotely program all motor protection parameters. The computer keeps track of the energy, current, voltage, power, and operating hours.

The running hours data can be used to plan motor maintenance.
