Critical Load Resistance of Shunt Wound DC Generator
This is the minimum external load resistance which is required to excite the shunt wound generator
Explain the different types of dc motor with neat sketch. Last Answer : DC MOTOR TYPES Shunt Wound Series Wound Compound wound 1. Shunt Motor In shunt wound motor the field winding is connected in parallel with armature. ... that it shunts the series combination of armature and series field it is called long-shunt connection. ...
Explain the characteristics of dc shunt motor. Last Answer : Characteristics of DC Shunt Motor: The three important shunt characteristic curves are 1. Torque Vs Armature current characteristic (Ta/Ia) 2. Speed Vs Armature current ... the armature torque is directly proportional to the armature current, the starting torque is not high ...
With a neat circuit diagram Explain the construction and principle of operation of DC Generator Last Answer : DC Generator: A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically ... current reversal occurs. And therefore, we get unidirectional current at the terminals. ...
Mention the application of DC generator? Last Answer : general lighting. Used to charge battery because they can be made to give constant output voltage. They are used for giving the excitation to the alternators. used for small power supply....
Describe various types self -excited of DC generator with their circuit layout. Last Answer : DC generators are classified based on their method of excitation. So on this basis there are two types of DC generators:- Self-excited DC generator can again be classified as 1) DC Series generator 2) DC ... (Rse is wired in series to the armature). It is shown in figure (2) ...
