...be returned to the grid or quickly dissipated by a braking resistor. Otherwise, the dc bus will be overcharged and an over-voltage fault can occur. Dynamic braking resistors have been widely used to convert regenerated energy into heat loss because of simplicity and low installation cost, as illustrated...

DB WR2 = Total inertia including motor inertia and coupled load inertia (WR2 motor + WR2 load) R = DC motor armature circuit resistance and the resistance of the DB resistors (RArmature + RDB) 4320 = Conversion constant V = CEMF = [E (Applied armature volts) - IR] NOTE: Motor inertia can be found...

Energy, which is being generated during the braking process of fast rotations or heavy masses, used to be converted into useless heat by means of bulky brake resistors. Today, innovative drive technologies allow the regenerated energy to be fed back into the supply grid for further use. The new...

...permitting). Dynamic braking (motor-generated energy is fed to a resistor grid) or regenerative braking (motor-generated energy is fed back into the dc supply) can be obtained with dc motors on applications requiring quick stops, thus eliminating the need for, or reducing the size of, a mechanical...
