Scientech 2457 DC Motor Speed Control is built around a compact permanent magnet DC Motor. The system can readily be configured to control speed of DC Motor using Pulse Width Modulation technique. Motor load can be varied by using built in eddy current brake . Facilities are available to directly measure the principal performance features of the speed control system, viz, steady state error and load disturbance rejection, as a function of the forward path gain.

Scientech 2457,?DC Motor Speed Control?is an ideal teaching aid?to enhance education, training, skills & development amongs our young minds.
