During dynamic braking, the motor operates as a DC generator after the main power is removed.

Explanation:
During dynamic braking, the motor’s own rotational energy is converted into electrical energy by the machine acting as a generator. Once the main power is removed, the spinning armature induces a voltage (back EMF). This generated current is directed through a braking resistor (or a braking circuit), where the electrical energy is dissipated as heat. The flow of current creates a braking torque that opposes the motor’s rotation, slowing it down quickly. This is why the motor behaves like a DC generator in this braking mode.
