Answer / nirbhay

A linear motor is essentially a multi-phase alternating
current (AC) electric motor that has had its
stator "unrolled" so that instead of producing a torque
(rotation) it produces a linear force along its length. The
most common mode of operation is as a Lorenz-type actuator,
in which the applied force is linearly proportional to the
current and the magnetic field (F = i × B).

Answer / dolphin

nirbhay's answer is absolutely correct. the jet
trains in japan which can accelerate their speed
upto 500km per hour
are the best examples of linear motor. here the
train acts as a linear rotor which is excited with
3 phase supply and the rails act as a unrolled
stator which contains short circuited cross bars.

what is the AC Plant and how can do the work with parts and picture tell us 150 Tr

Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
