Will it be possible in the future or now to design an electric motor with 100 percent or more efficiency?

Question

Will it be possible in the future or now to design an electric motor with 100 percent or more efficiency?

Answer 1

Nope.  100 percent efficiency is thermo- and electro-dynamically improbable (but not impossible).  More than 100 percent efficiency is impossible by the simplest energy conservation laws.

Answer 2

No, and no.  You cannot get more than 100% efficiency.  And you can never achieve 100% efficiency; there will always be losses somewhere in the system.

Answer 3

no

more than 100% is impossible, you cannot get more energy out than you put in, and the inefficencies in the wire and connections, friction, eddy currents, air resistance, and electrical resistance makes it almost impossible to get it much higher than 85%

Answer 4

No, 100 % is fantasy. You will always have some loss from friction, and unless you can build a motor with a supper conductor, loss to the wire.

Answer 5

No, because the thing that spins around in the motor will always be fighting against friction.  So an electrical motor  can never be 100% efficient.

Answer 6

To get more than 100% efficiency, you would have to create a perpetual motion machine that violates the conservation of energy.  That is, such a machine would create energy from nothing.  This is not possible.
