5 Questions
What is the characteristic of a series motor compared to separately and shunt excited motors?
It requires less current for the same torque
What is the main advantage of a compound motor over a shunt motor?
It provides high starting torque
How does the total field flux of a compound motor differ from that of a shunt motor?
It depends on the combination of series and shunt field strengths
What happens to the speed of a differential compound motor when the series field strength increases?
The speed decreases
What is the relationship between armature voltage, field flux, and torque in speed control of DC motors?
The speed is directly proportional to armature voltage and inversely proportional to field flux and torque
Test your knowledge on DC machines and transformers, focusing on topics such as torque-current characteristics, speed-torque characteristics, and the steady-state equivalent circuit of the armature.
