Electrical braking

Overview
Braking with the motor in generator operation
If the motor brakes the connected load electrically, it converts the kinetic energy of the motor
into electrical energy. The electrical energy E released when braking the load is proportional to
the moment of inertia J of the motor and load and to the square of the speed n. The motor
attempts to transfer the energy on to the converter.
