To determine the efficiency of the DC Machine as motor at , , and. This test required two identical shunt machine which are coupled mechanically and also electrically in parallel. SPEED CONTROL OF DC SHUNT MOTOR BY DR.
SWINBURNES TEST ON DC SHUNT MACHINE BY KADAPALLA PRAVEEN - Duration: 13:49. EXPERIMENT LIVE SHUNT GENERATOR AND DC MOTOR ELECTRICAL ENGINEERING.
In the previous post we have seen how to determine the efficiency of DC machines using brake test.
Two similar DC shunt machines are coupled mechanically and parallel connected across the DC source.
Explanation,(b) Numerical (C) Disadvantage. TESTING OF DC MACHINE Q:- Why testing are required ? Output current of the generator. To understand the factors on which various losses depend upon.
To know how to calculate efficiency.
Hopkins Testing of DC Machines also dc motor generator test. Debaprasad Kastha, Department of Electrical Engineering, IIT Kharagpur. Out of different methods available for testing of d. Generally the motor is started first.
In Hopkinsons test one machine runs as motor and other as generator. To make it as simple as possible, the total input to the generator is output of the motor.
The open circuit test gives the mmf and. One machine is used as motor and drives the other and the other is used as generator and feedback the power into the supply. Two machines are mechanically . Determination of performance curves.
Load test on DC compound generator. Predetermination of efficiency.
Fields test on DC series machines. Find resistance to be added to the. A 2V, dc shunt motor has an armature resistance of 0. Moreover, robotics for soft-tissue.
