WARD LEONARD METHOD OF DC MACHINE TRAINER KIT

Category: Electronics

Model No: IEE-WARD-DC

The product demonstrates the Ward-Leonard Method of DC Machine through which user can not only operate but also control the speed of DC Machine in either direction without using DC supply. Separate terminals of Armature and Field windings are brought out on a terminal box fitted on top of the Motor so that one can connect them separately to the panel and can perform experiment correspondingly. Reverse connecting Switch is provided to control the speed of DC Motor in either direction.
