Swinburne’s test and speed control of DC shunt motor. Hopkinson’s test on DC motor – generator set. Anna University - Control System Lab Manual - Anna University - PROBABILITY AND QUEUING THEORY Q Anna University - Engineering Chemistry - 1 - Nov.  · Fig:Field Rheostat control For a DC shunt motor. The value of controlling resistance to provide a desired increase in speed can be determined form the magnetisation characteristics of the machine. Let the initial values of back emf,flux and speed be Eb1,Φ1 and N1 respectively and let the back emf and flux be Eb2 and Φ2 respectively at new.  · To study the speed control of a DC shunt motor by the following methods: The speed of a DC motor is given by N = K1 rpm. EDC Lab Manual. Laboratory Manual Electrical Machines Lab provides the essential facilities to the students to augment their SPEED CONTROL OF .

Shunt DC Motor when shunt resistance is about When the eld resis-tance is low, the rotational speed of the motor is high keeping the eld current approximately constant.
