Simplified installation and energy savings with regenerative drives
With regenerative functionality, the braking energy of the motor is returned to the drive and distributed to the supply network so that it can be utilized by other equipment. Everything needed for regenerative operation are included in the drive. The active supply unit allows full power flow in both motoring and generating modes.
When electric motors slow down, stop, or change speed, they naturally generate braking energy. In traditional systems this energy is wasted as heat through resistors or mechanical braking, requiring extra equipment and sometimes even additional cooling. Regenerative drives change the equation by capturing this otherwise lost energy and feeding it back into the electrical network, where it can be reused immediately by other equipment. Instead of being lost, braking energy becomes a valuable resource.
This approach brings clear practical advantages. Because no bulky external braking devices are needed, installations are more compact, simpler to design, and easier to maintain. At the same time, the absence of excess heat reduces the need for cooling systems, which further lowers costs and complexity. Regenerative drives also enhance power quality by minimizing harmonics and stabilizing voltage, creating a cleaner and more efficient electrical environment.
For businesses, the benefits are straightforward: energy savings, lower electricity bills, and reduced environmental impact thanks to improved energy efficiency. Processes run more reliably since motors receive full voltage even when the network supply fluctuates, reducing the risk of interruptions. With regenerative drives, companies not only cut costs but also gain greater uptime and sustainability in their operations.
