Why are there not electromagnetic motors?

[burro breath 10+ year member]

Ok so I was thinking today as to why there are not speakers with two coils. One for the motor and one for the speaker. And they would use two amps. One for the motor and one forthe speaker. If they were in opposite phases they would repel one another. Would this increase effitientsy sorry poor spelling.

get your masters degree in engineering.

THEN

design a prototype

Becuase you touch youself at night. That's a sin in RoboRaptorJesus' eyes...

this would be overpriced and extremly inefficient.

not to mention point less for something that is already being done fine just the way it is.

I'm in school for engineering. But I was being serious for those with dumba$$ remarks

They do exist. They're called field coil drivers.

RoboRaptorJesus doesn't love those who study engineering...

me?

They do exist. They're called field coil drivers.

aka rail guns.

or alternators.

too much power would be needed and efficiency as far as electrical needs would go way down

why have 2 amps do the same thing that 1 amp could and be 2 times more efficient at?

Actually, less power is needed.

The field coil has it's own power supply and the voltage can be adjusted for the permanent coil, providing almost limitless T/S parameter flexibility.

even in a car situation?

I was joking around about this type of driver not long ago.

JL would probably just do it the easy way
