Write a technical manual of that will inform others of the efficiency and inefficiency of all types of motor and generator (ac and dc). Explore how any apparent inefficiencies could be improved. Show examples of these machines and using suitable examples, point out the areas of inefficiency (if applicable) and where and how things can be improved. Then provide the solution to the following as an example in your report. A 2-pole, single-phase alternator driven at 3000rpm require a mechanical input to its rotor of 30kW when it is delivering its full-load output of 30kW. Under this condition the fixed and variable losses are1100W and 2.8kW respectively, and the rotor field winding is supplied from a 110V dc source. Given that the full-load efficiency is 87%, determine. i) the frequency generated, ii) the input driving torque on full-load and iii) the rotor field current
