Clarifications about a linear induction motor.
-Calculate the force of a linear induction motor from the magnetic field/current (aluminum induced surface)?
-How does one determine the direction in which is moves considering the magnetic fields are not static and there isn't a second magnet since it is just an aluminum induction surface?
-Is there an optimal current frequency for a linear induction motor?
-Is there any way to make a single phase Linear induction motor, and avoid using 3 phase current?
