Embedded Technology, Variable Frequency Drives and Efficiency

Lowering energy consumption in large embedded devices is a challenge. Right now, the best bet is the motor drive. In motor drivers, variable frequency drives have shown a lot of potential. These adjustable speed drives control torque and AC motor speed by varying the input voltage and frequency. But for all their advantages, the global market penetration of VDF running application is still very small, which may indicate that there are significant opportunities to increase energy efficiency. In the last few years, there has been a shift towards smarter and more effective motor drives. For example, in water treatment, manufacturing, HVAC and many other industrial settings.

Meeting these requirements is an exciting opportunity for embedded designers and software development. It is especially true in case of the latter because software has better opportunities to design efficient embedded systems. The trend towards smarter and more efficient motors is actually good for companies in this field because it can help them respond better to global regulations on carbon footprints. It also makes economic sense because lower electricity bills affect customers directly. More efficiency designs will also reduce machine downtime and improve reliability thanks to lower wear and tear.
