During the rheostatic braking of a dc motor
WebJun 1, 2016 · The energy during braking, for the single motor or multimotor (with common DC bus) DC drive systems, can be regenerated into the AC power line or can be used by the other drive systems. WebJan 26, 2007 · Series excitation DC motor, most commonly used for traction, cannot operate during regenerative braking because, when the external load is decreased, the speed of the armature revolution increases stepwise (theoreti-cally up to ∞). Thus, the conditions for the motor at idle to exceed point n 0 of torque-speed characteristic
