Rewind 3 phases motor for higher power rating?

[citfta]

The confusion comes from the idea that higher voltage alone produces more power.  That is NOT true.  Higher voltage at the same current DOES produce more power.  BUT if you rewind a motor with smaller wire so that it will run at a higher voltage you have reduced the amount of current the wire can carry.  So you lose power from less current and don't really gain anything.  The engineers that designed the motor you want to rewind understand all that.  So they designed the motor to operate at a particular voltage and current.  You can rewind it for a higher voltage but because of the lower current the power out will probably be the same or less than the original motor windings.

Thank you Sir for the explanation!!!

*EV Gray Motor vs Tesla Motor...*

A clear connection has been made between the radiant energy work of Nikola Tesla with the later (1973-75) work of Edwin Gray. It now appears evident that EV Gray knew a lot more about the Tesla Pierce Arrow car demonstration in Buffalo NY in 1931 than any of us involved in this new radiant energy area!

The similarities between the two radiant energy project specifications and detail are most remarkable.

Both used electric motors rated at about 80HP (Tesla's in his Pierce Arrow car and Gray's on a test bench). They also both used standard auto batteries (6V or 12V) for the power source for the radiant energy conversion process.
Both used special radiant energy conversion tubes. Tesla used twelve (12), while Gray used three (3) as described in the two EV Gray radiant energy conversion tube patents.
Both used matching capacitor banks rated at 5KVA each. Tesla used twelve (12), for a total of 60KVA (KW), while Gray used three (3) for a total of 15KVA.
The key design point for Tesla's car system was that his power rating of 60KVA equates to 80HP so that all of his design specifications match the full power rating for his car. How then, did EV Gray come close to achieving his 80HP rating?

We now know that he did this with a specially designed electric motor as the major innovation for EV Gray power system! There is no longer much speculation about this Gray design reality, because Norm Wootan of Texas, had in his possession motor #4 and #5 of Grays prototype motor series.

These EV Gray motors were shown at the KeelyNet meeting in June 2001. (Videotapes of that presentation are available from TeslaTech.) Since then a Canadian inventor has gained possession of them.''

Why
the motor used by Nikola Tesla in his electric car rated  60kw?

We can use in EV:
Battery + DC motor
Or
Battery + three phases inverter+ three phases ac motor
