What is the difference between dynamic and regenerative braking?
Dynamic braking wastes all electrical energy as heat in a resistor while regenerative braking returns some power to the supply source by reversing the motor operation into generating mode.
Which braking method is most energy efficient?
Regenerative braking offers the best efficiency as it feeds a portion of the braking power back to the original source of energy unlike the other two methods.
Can plugging braking damage the motor?
Yes, plugging braking may induce excessively high currents that can overheat motor windings if not implemented properly with current limiting controls.
What are applications where dynamic braking is preferred?
Dynamic braking is suitable in applications requiring braking regardless of motor rotation direction or load like holding press components in position between operations.
Is plugging braking recommended for frequent stops?
No, plugging braking puts significant thermal and electrical stresses on motor components. It is only used for emergency stops or infrequent high deceleration requirements.
