The Ward Leonard System is basically used to control the speed of a DC Shunt motor by controlling its armature voltage. The Ward Leonard System consists of a Primover coupled to a DC Generator. The DC Generator output is fed to the armature of separate DC Shunt motor called as the Control Motor. By controlling the Field Current of the DC Shunt Generator, armature voltage of the Control motor can be controlled whereby the speed of the control motor can be varied. The unit consists of a DC Shunt motor as primover, coupled to a DC Generator and a DC Shunt motor as Control motor. All motors are rated at 2HP. The control panel consists of Starter, Voltmeters, Ammeters, RPM meter and Field Supply and Control.
