It is no secret that electric motors consume tons of energy, and the endeavour to achieve efficiency improvements, no matter how small, remains at the forefront of the priorities of the organisations that rely on them. Switching to higher efficiency models is one way to achieve this goal, but it is not always feasible as their cost and different operating characteristics typically require a complete redesign or reprogramming of existing electrical cabinets and other associated equipment.
Fortunately, there are plenty of other avenues to explore before resorting to such a high-investment approach, such as electric motor rewinds. Another option that is gaining traction across industries is leveraging automation, which is the concept of using technology to perform various tasks with minimal human intervention. From manufacturing to logistics and many other industries, automation has become integral in introducing substantial efficiency improvements across various aspects of their operations, and it too can do the same for operating electric motors. Read on to learn more exactly how.
Achieve Optimised Motor Control In Real Time Using Sensors
Automation technology can significantly improve a motor’s efficiency and reduce its consumption through accurate controls of its speed and output with the help of IoT sensors and electric motor controllers. When combined with automation, they can automatically start and stop a motor, regulate its speed, limit torque, and forward or reverse rotation with precision to ensure no energy gets wasted.
Additionally, automation can help reduce a system’s overall energy consumption by managing its power supply. Specifically, it could be programmed to perfectly adjust the performance of the power supply’s many components such that they only use the minimum energy required to function well.
Allows For Maximising Innovative Control Techniques
As mentioned, automation goes hand in hand with electric motor controllers like variable frequency drives to achieve specific performance goals. Beyond accurate adjustments of parameters like current, voltage, and frequency, controllers also allow sophisticated control techniques to be automated to further optimise motor performance. An example of this is vector control, which entails decoupling flux control and torque to achieve greater responsiveness and dynamic performance. The net result is, more often than not, a dramatic reduction in energy consumption, especially in fan and pump systems, which typically run around the clock.
Enhancing Energy Management
Integrating motor control, automation, and energy management systems creates more efficient plant operations. Automation systems can collect and analyse energy data from motors, enabling better alignment of motor function to workload. This data-driven approach allows for more informed decision-making, leading to optimised energy usage and cost savings. Furthermore, automation can facilitate the implementation of energy-saving strategies, such as load shedding and demand response, further enhancing overall energy efficiency.
Conclusion
When implemented well, automation has the potential to dramatically enhance the efficiency of electric motors in various operational settings. By integrating advanced sensors, real-time monitoring, and intelligent controls, automation can optimise motor performance with extreme precision and accuracy, effectively reducing energy consumption and even minimising downtime. This leads to significant cost savings, improved reliability, and a more streamlined workflow. As automation continues to evolve, its role in boosting the efficiency and longevity of electric motors will only grow, making it an indispensable tool for modern industries.
