The difference between Reversible vs. Regenerative DC Drives.
First: Let’s see what they have in common:
Ø Both can run DC Motors in both directions.
Ø Both can be controlled manually or with a PLC.
Ø Both drives are suitable for applications requiring frequent changes in direction, although Non-Regenerative-Reversible Drives don't prioritize energy efficiency during braking, as the kinetic energy is often dissipated as heat.
Second: Let’s see the advantages of the regenerative DC Drives.
1. Regenerative DC Drives Generate Power and send fed back into the power source (the Power Company), while deceleration and when stopping (braking), which saves you money.
2. Regenerative DC Drives DO NOT need electromechanical components, like relays, contactors, etc. Because they switch direction electronically.
3. Regenerative DC Drives DO NOT need the “Brake Resistor” to stop the Motor every time it needs to run in the opposite direction.
4. Regenerative DC Drives can change Rotation direction instantly maintaining full power and torque.
5. Regenerative DC Drives can be used as a Servo-Drives in most applications, which makes a huge difference in operation’s cost reducing them, because Servo-Equipment is much more expensive.
6. Regenerative DC Drives DO Pump Power Back to the Utility Company while deceleration and when they stop. Thus saves money to the company.
7. Regenerative DC Drives are suitable for applications requiring changes in rotation direction and are specifically designed to recapture energy that would otherwise be lost during braking or deceleration.
8. Regenerative DC Drives not only control the speed of the Motor’s direction but also the direction of the Motor’s Torque.
9. This regenerative capability significantly improves overall energy efficiency, especially in applications with frequent braking or overhauling loads (where the load is trying to drive the motor).
