As available energy becomes more difficult
and expensive to obtain, the efficiency of
electrical devices such as motors becomes more important.
Write a paper on electric
motor efficiency which deals with such questions as:
- relationship between efficiency and original cost
- relationships between energy cost, motor efficiency,
original cost, etc
- importance of motor size and load
