What Are The Braking Methods Of DC Motors
Leave a message
The braking methods of DC motors include mechanical braking, regenerative braking, energy consumption braking, reverse connection braking, and regenerative braking.
The mechanical brake is the holding brake, which is an electric holding brake, also known as the brake.
Dynamic braking refers to the sudden disconnection of the armature power supply of the DC motor in operation, and then a braking resistor is connected in series in the armature circuit, so that the inertial energy of the armature winding is consumed on the resistor, and the motor is braked quickly. Since the voltage and input power are both 0, the braking is balanced and the circuit is simple.
Reverse brake. In order to realize fast stop, the armature voltage of the running motor is suddenly reversed, and a resistor is connected in series in the armature circuit, which is called power reverse connection braking. During braking, the power supply still inputs power, and the kinetic energy and electromagnetic power released by the load are both consumed on the resistance. When reverse braking, switch the power supply voltage with opposite polarity to generate reverse current in the armature circuit. Prevent.
