How linear induction motor work?

Answer 1

The linear induction motor works on the same principle as that of normal induction motor with difference that instead of rotational movement, the rotor moves linearly. If the stator and rotor of the induction motor are made flat then it forms the linear induction motor. The flux produced by the flate stator moves linearly with the synchronous speed from one end to the other. The synchronous speed is given by,

v

s = 2wf

where v

s = Linear Synchronous Speed (m/s)

w = Width of one pole pitch (m)

f = Frequency of supply (Hz)

It can be seen that the synchronous speed is independent of number of poles but depends only one width of pole pitch and supply frequency.

Answer 2

A linear motor is an electric motor that produces a linear force along its length. There are several different types of linear motors including induction motor, synchronous, homopolar and Piezo electric.
