regenerative braking is a method which is used to to stop
the DC motor immediately against moment of inertia.A
regenerative brake is a mechanism that reduces vehicle speed
by converting some of its kinetic energy into a storeable
form of energy instead of dissipating it as heat as with a
conventional brake. The captured energy is stored for future
use or fed back into a power system for use by other
electrical equipment.
