How to realize the energy consumption braking of the excitation DC motor

How to realize the energy consumption braking of the excitation DC motor

Answer:

When the motor is operated in an electric state, if the armature voltage U is suddenly dropped to zero, the armature is connected with an additional resistor R. The two ends of the armature are disconnected from the power grid and are quickly connected to an appropriate resistor.

The motor is in the running state of the generator, converting the kinetic energy of the rotating part into electric energy and consuming the resistance

. With the kinetic energy consumption, the speed decline, braking torque is also becoming smaller and smaller, so this brake method is still relatively high in speed, braking role is relatively large, with the decline in speed, braking effect also decreases

Energy consumption brake is divided into two kinds, which are used for different occasions: quick stop and lower weight. If the motor is dragging against the constant torque load, then through the quick stop method for energy consumption braking, if drag potential energy, constant torque load, then through the lower weight to carry out energy consumption braking.
