Digital Torque Amplifier has been designed having horizontally installed two capstans that are positioned in common line of rotation. It is required for amplifying torque of rotating shaft without creating any effect on its rotational speed. This amplifier is widely utilized in automobile power steering systems and on differential analyzers. It is also known to find application in various industrial machines and gearboxes of tractors as well. Offered Digital Torque Amplifier is a microprocessor based device which assures high torque ratio. It is provided with a digital display for showing real-time torque values.
