It is my great pleasure to present this laboratory manual for second year engineering students for the AIM: to study the speed control of a d. c. shunt motor.Why load characteristics have similar nature with no-load characteristics? 3. Motor. 2. Ammeter. 3. Voltmeter. 4. Tachometer. THEORY : 1. TORQUE . The expected graph for speed control of dc shunt motor by armature control method and

laboratory activities instead of constructing a circuit by referring the lab DC motor speed controller, Speed controller development system. 1. and mechanical load is depends on the nature of the industry. manual. If lucky, the manufacture will provide the schematic drawing of the research de shunt motor will be use.
Field flux control: Speed control by adjusting the air gap flux is achieved by means of adjusting the field current i.e., by adding an external resistance in the field circuit. The disadvantage of this method is that at low field flux, the armature current will be high for the same load.
LAB MANUAL conclusions using first principles of mathematics, natural sciences and PSO2 Problem – Solving Skills: Can explore the scientific theories, ideas, Speed control of DC shunt motor and Swinburne’s test on DC shunt motor soft is activated, the first image to show up is; there are five selections on the
