Ward Leonard control provides speed control in both directions.
The Ward Leonard control system is a method used for controlling the speed and direction of DC motors. It consists of a motor-generator set (M-G set) and a control circuit.
The M-G set, which includes a motor generator and a generator, is responsible for converting the fixed-voltage and fixed-frequency AC supply into a variable DC voltage. The control circuit regulates the voltage applied to the motor’s armature, thus controlling its speed.
By adjusting the control circuit, the output voltage of the motor generator can be varied, allowing for speed control of the connected DC motor. This control system enables the motor to operate at various speeds in both forward and reverse directions.
Therefore, Ward Leonard control provides speed control in both directions. The correct answer is A: In both directions.
