Main system losses of transformer fed, geared electrical drive system for ships propulsion, from the electrical power source through to the propeller?

did u make the ac generator or buy it I think there is no change in magnetic flux done by the coil your voltage depends on the number of turns and change in flux according to faraday
...

Yes

If u charged the after one year then obviously it can't charged but I will suggest u to take out the battery and give it the high voltage e.g. if battery is 12v then u have to give it 20 volts this...

Every cable has the ambient temperature for example 40*c if the temperature of the surrounding is greater than the ambient temp of the cable then the conductor of cables become heat up which...

Thanku yes I know that calculation is different frm the practical

as u know the formula of power is P=sqt3*V*I
1hp=746w
7.5hp=746x7.5
=5595w
so 5595=208xI
and I=5595/208x1.73
I=15.5A

the formula of resonance frequency is
fr=1÷2π√ LC

fr = 1.3kHz

In SI unit 1 Nm = 0.738 ftlb
so 1/0.738 = 1 ftlb
1.355 Nm = 1 ftlb
(1.355 x 100 x 300) Nm = (100 x 300)ftlb
406.5 Nm = 300 ftlb
so P = nT/9.55
where P in watt, 'n' is an rpm, T in Nm and 9.55...

In SI unit 1 N·m = 0.738 ft·lb
so 1/0.738 = 1 ft·lb
1.355 N·m = 1 ft·lb
(1.355 x 100 x 300) N·m = (100 x 300)ft·lb
406.5 N·m = 300 ft·lb
so P = nT/9.55...

It depends upon the current rating of the motor I-e if motor current rating is 1 amp then you use the diode which have current rating greater than the motor I-e 1.5 or 2 amp

The difference between single phase and three phase is that the single phase is just an alternating waveform of about 110 or 120 volt where as two phase are the two alternating waves that are 180...
