How linear induction motor work?
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.
Are the friction losses of the machine linear in induction motor electrical machines?
yes
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
Application of induction motor in industry?
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.

Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
Are the friction losses of the machine linear in induction motor electrical machines?
yes
What are the advantages of single phase induction motor?
the torque requirement of single phase induction motor is less,and it is use for low power applications upto 1 to 10 kw.like in fans,mixiers
Why is the efficiency of a three-phase induction motor about 85-87percentage?
Not always. I have seen induction motors for various applications having efficiency upto 95%.
Does induction motor works on Electromagnetic induction?
Yes the Induction motor works on Electromagnetic induction principle.
What is induction motor?
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
What are the End effects in linear induction motor?
due to the finite length of primary core and windings of linear induction motor, the phenomenon so produced is called as end effect. this can be categorized further as dynamic end effects and exit end effects.
What has the author R P Chen written?
R. P. Chen has written: 'Linear induction motor research vehicle wheel/rail adhesion test' -- subject(s): Car-wheels, Electric motors, Induction, Induction Electric motors, Testing
What is a decripition of Nikola Tesla induction electric motor?
AC Induction Motor
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.
