Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load.

NSCET LAB MANUAL DEPARTMENT OF ELECTRICAL AND ELECTRONICS ENGINEERING Armature Resistance (Ra):- + 230 V (0-30V) Theory: . By conducting load test on DC shunt generator we can get load characteris- tics i.e, Internal & External characteristics. By exciting the m/c, the field current increases and voltage build up.. A dc shunt motor rated at 240 V has a field winding resistance of 120 Ω and an armature resistance of 0.12 Ω . The motor is supplied at the rated voltage. Under the no-load condition, the motor draws a line cureent of 4.75 A.

DETERMINATION OF DC MACHINE EFFICIENCY BY BACK-TO-BACK TEST (Hopkinson Test) INTRODUCTION: This is a regenerative test in which two identical dc shunt machines are coupled mechanically and tested simultaneously. One of the machines is made to act as a motor driving the other as generator which supplies electric power to motor.

Put on the load by tightening the screws of the spring balances. Note down the spring tensions, the speed, the voltage and the currents at different loads until full

The DC Shunt-wound motor, running on Direct current, has its field windings placed in parallel to the armature. In Electrical terms, parallel is generally denoted as shunt. That is the reason behind naming it a DC Shunt motor. Same voltage is applied to both shunt winding and armature in this motor. This parallel configuration allows independent path of current for field winding and armature.

LOAD TEST ON THREE PHASE INDUCTION MOTOR AIM: (a) Perform load test on 3-phase induction motor. (b) Compute Torque, Output power, Input power, Efficiency, Input power factor and Slip for every load setting and to determine how speed, efficiency, power factor, stator current torque, and slip of an induction motor vary with load.

DC Motors Protocol

Conclusion: In this lab experiment, the DC motor speed control was studied. Taking the previous Simulink models from lab 1. This lab allowed us to further investigate the characteristics of the various DC motor speed control schemes. There are two types of controls which were made in order to control the speed as well as the current. In an open loop control, the only components in the system

Electrical Lab Load Test on Dc shunt generator

Consider a dc shunt motor running at no-load. (i) If the supply to the armature is cut off but the field remains normally excited, the motor slows down gradually and finally stops. The kinetic energy of the armature is used up to overcome friction, windage and iron. In the retardation test, the dc machine is run as a motor at a speed just.
