Project on Speed Control of DC Series Motor Using MATLAB Simulink 1.0 Introduction Speed control is an electric circuit which purports to vary an electric motor's speed as well as its direction and possibly also act as a dynamic brake. It could be a stand-alone unit which plugs into the receiver's throttle control channel or incorporated into the receiver itself. Speed control is designed for use in cars to reversing capability as well as helicopters, airplanes and boats. In series motors, the field windings are connected in series with the armature coil wherein the field strength varies with changes in armature current. When the speed of series motor is reduced by a load, the series motor develops greater torque. Its starting torque is greater than other types of dc motors. The speed varies widely between full-load and no-load. Further, counter-electromotive force is generated in a dc motor as armature coils cut the field flux and this emf opposes the applied voltage and lim...
