THIS! I have two classes using this book.. Introduction to Electrical Machines, and Industrial Control Circuits.
We are 6 weeks in and I have absolutely NO clue as to what any of it means.
If there is anyone out there in Tumblr land that can tutor me on EMF, Faraday, Teslas, AC/DC Motor Theory and control, I would be more than willing to compensate you for your time. I have not been able to locate a tutor locally and am already starting to fall behind. I have had no physics classes so I was at a disadvantage from the beginning.
An example problem is as follows:
The efficiency, at rated load, of a 100hp 600V shunt motor is 85%. The field resistance is 190ohm and the armature resistance is 0.22ohm. The full-load speed is 1200rpm. Find (a) the rated line current, (b) the armature current at full load, (c) the counter emf at full load, and (d) the field current.
