Ward-Leonard control is generally a:
- Armature voltage control
- Armature resistance control
- Field diverter control
- Field control
Correct answer: 1. Armature voltage control
Explanation: The Ward-Leonard control system is a method used to control the speed of a DC motor. In this system, a DC motor is connected to a generator, and the speed of the motor is controlled by varying the voltage applied to its armature. The generator, known as the motor generator set, consists of a motor (drive motor) and a generator (generator motor). The speed of the drive motor is controlled by adjusting the voltage applied to its armature.
So, Ward-Leonard control is generally associated with armature voltage control, as it involves regulating the voltage supplied to the armature of the DC motor to achieve the desired speed control.
