magnetization characteristics of dc generator
I was going through an article about DC Shunt Motors when i came up with some unknown concepts... I searched some books but none explained the concepts i needed... can someone please help me with the following:
1. What are the magnetisation characteristics of a DC Shunt Motor?
2. What is its Significance?
3. How to draw the Magnetisation Characteristics given some data about its Open Circuit Voltage and Field Armature Resistance - TABLE
4. How to calculate the various parameters like Critical Resistance, Critical Speed from the graph and from the data given...
5. What is Critical Resistance, Critical Speed?
