A '''linear induction motor''' (LIM) is an AC asynchronous [[linear motor]] that works by the same general principles as other [[induction motor]]s but
Linear motors frequently run on a 3 phase power supply.
Their uses include [[magnetic levitation]], linear propulsion, and linear actuators. They have also been used for pumping liquid metals.<ref>http://books.google.co.uk/books?id=fgsAAAAAMBAJ&lpg=PA52&ots=NfAng_7A27&dq=einstein%20Linear%20induction%20motor&pg=PA52#v=onepage&q=einstein%20Linear%20induction%20motor&f=false</ref> Despite their name, not all linear induction motors produce linear motion, some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive.
