Hi Guys
I'm hoping someone can help me out with a problem??
I have just started learning about DC motors and I have hit a wall on how to solve the following problem-
Q.The output of a series d.c. motor when connected to a 230V supply and running at 1320rev/min is 3.8kW. The supply current for this loading is 20.5A.
Calculate the torque developed and the opperating efficiency??
Can anyone explain the equations i need to be looking at, as I thought you needed the armature current and field current to be able to solve this??
Any advice or help is much appreciated
