There is no such thing as a Generator. All power generating
devices are Alternator since both generate alternating
current since this is the only way electrical power can be
generated. In "generators" the alternating current is
converted into DC inside the housing of the "generator" in
order to give out DC
Do you agree? If not please educate me. How else is DC
generated if not like above?

how does WTI work ?
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?

sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
why to use 50hz only in tansmisson and as well as in distribution why not60hz?
extremely urgent please, why a fuse is used before voltmeter but not with a ammeter connected to a CT(current transformer),thanks in anticipation.
