How Does MCC Switchgear Support Motor Control

Motor control ensures that production lines operate in a safe and efficient manner, thereby impacting productivity and efficiency in the process. As one key component integrated with the power supply and control, monitoring, and protection features, the MCC switchgear (Motor Control Center Switchgear) offers support in the control of the industrial production line motors. Most industrial enterprises may not have a straightforward understanding of the motor control support functions MCC switchgear offers. This blog seeks to clarify in multiple ways the support functions MCC switchgear offers motor control in a reliable manner, and the importance of MCC switchgear to enterprises in the optimization of motor control to maintain production line stability.  

Way 1: Provide a Durable and Focused Power Supply for the Motors  

One of the many ways an MCC switchgear offers support for the control of motors is through a durable and focused power supply. Within an industrial site, multiple motors (conveyor belts, compressors, and pumps) operate continuously, drawing power. Each MCC switchgear integrates multiple power distribution units, and the MCC switchgear is responsible for the power source and distribution of the control switchgears. Each control switchgear is configured to draw concentrated power and control one motor, drawing the mess of distributed wiring and ensuring stable voltage and current for each motor.

In a workshop that has 20 motors, MCC Switchgear prevents voltage fluctuations that may occur when there is uneven power distribution as the MCC Switchgear controls the power/output according to each individual motor load. As voltage fluctuations are avoided, the MCC Switchgear ensures that power to the motors is supplied uninterrupted which is vital to the operation of the motors.  

Another way is to prevent motor damage with fully comprehensive protection which MCC Switchgear powers motor control. Motors operate with the potential to incur damage due to overcurrent, overload, short circuit and phase loss. If these issues occur, MCC Switchgear will power down the motor to protect it from running and incurring more damage. Protection components are built into the system such as circuit breakers, thermal overload relays, phase failure protectors and the like. These components ensure that motor operating parameters are kept within a safe operating range. If there is a range overstepped, MCC Switchgear will trip the motor and prevent it from incurring damage.

When a pump motor stalls and causes an overcurrent, the MCC switchgear will activate overcurrent protection in under 0.5 seconds. This fully automated MCC switchgear functions as a “safety barrier” in protecting the motor. 

Way 3: Facilitating the Centralized Control and Operation of Several Motors 

The MCC switchgear facilitates centralized control and operation of multiple motors, applied in a number of industrial sites with many motors. Without an MCC switchgear, an operator must control each motor independently, and since each motor has an independent switch, this approach is inefficient and facilitates operational errors. In the MCC switchgear, the operator has centralized control of all motors which allows him/her to start, stop, and control the speed of each motor through buttons, knobs, or touch screens. In a water treatment plant with 15 pump motors, the operator uses the control panel in the MCC switchgear to monitor all the motors and start or stop specific motors with one touch in the sequence required by the water treatment process. This approach saves operator effort, enhances control efficiency, and reduces the likelihood of operational errors. 

Way 4: Real Time Monitoring of Motor Operation Status 

The MCC switchgear streamlines motor control by providing real time motor operation status, which allows operators to make timely motor operation status updates.

MCC switchgear comes with sensors and display modules that gather important parameters of the motor (i.e., current, voltage, temperature, and running time) and present these on the control panel or send them to the upper computer system. These parameters can be accessed anytime by the operators to determine if the motor is functioning properly. Take temperature for instance. If the MCC switchgear shows that the temperature of a motor is too high (over 80°C), the operator can take action to avoid serious damage (overheating) by reducing the motor load or stopping it to inspect. By using real time monitoring, MCC switchgear is able to avoid reactive maintenance and ensure that motors do not suffer unscheduled interruptions. 

Way 5: Further Reduce Downtimes by Streamlining Maintenance and Troubleshooting  

Finally, the motor control supporting functions of MCC switchgear encompass the ease of maintenance and troubleshooting. In the event of a motor fault, switchgears can easily pinpoint fault locations. You will be notified of the number of the motor that has the fault and will specify the type of fault (i.e., short circuit or phase loss) which helps prevents the lengthy process of manually searching the fault for each motor.

Furthermore, the MCC switchgear uses a modular design, where each motor control unit functions as an independent module. This means that during maintenance, operators can deal with the faulty module without switchgear operational shutdowns, allowing other motors to continue to function. For instance, if a control module of a conveyor motor gets faulty, the operator can replace it in 10 minutes, while the other motors in the MCC switchgear continue to run. This quick and effective module design maintenance means reduced motor downtime, lessening the production impact of an operational fault.  

Conclusion  

To conclude, the MCC switchgear offers motor control optimisation in several ways. It ensures a steady and consolidated power supply, comprehensive protective coverage to avoid motor damage, central control and operation, real-time operation status monitoring, and maintenance and troubleshooting. MCC switchgear is critical equipment for industrial enterprises that depend on the operational ability of motors, as it optimizes motor control, enhances operational safety, and boosts production efficiency.
