Regenerative braking returns regenerated power of a DC motor back to the power source.

• A. True
• B. False
• C. Not applicable
• D. Unknown

Answer: (A)

During regenerative braking, the DC motor acts as a generator as it slows down. The rotating motor induces current in the windings (back-EMF), and the drive can route that electrical energy back into the power source instead of wasting it as heat. If the control system and power path are designed to accept returned power—such as feeding energy back into the DC bus, a battery, or the main supply—the regenerated energy goes back to the source. This is why regenerative braking is described as returning energy to the power source.

Keep in mind that some setups can’t accept returned power and instead dissipate it in braking resistors or other dissipative paths. But when the system supports regeneration, the energy naturally flows back to the source, making the statement true.
