
The principal of a Magnet train is that floats on
a magnetic field and is propelled by a linear
induction motor. They follow guidance tracks
with magnets. These trains are often referred to
as Magnetically Levitated trains which is
abbreviated to Maglev

LEVITATION is derived
from ‘levis’ means light.

A simple motor’s Stator is when Cut open and
flattened it becomes a Linear Motor.
Instead of producing a Rotational Torque it
produces a Linear force and thus is practically
suited to MAGLEV operation.
Speed control is achieved by Frequency control
or by varying the field Excitation by changing
the current direction.
There is reaction plate in which the current is
induced, thus producing Horizontal motion

Built by RTRI,Japan
Uses a Super
conducting Magnet.
Linear Synchronous
Motor Application.
Repulsion Type.
Guideway clearance is
up to 10 cm.
Expensive system
A repulsive force and an attractive force induced between the magnets are
used to propel the vehicle (superconducting magnet). The propulsion
coils located on the sidewalls on both sides of the guideway are energized
by a three-phase alternating current from a substation, creating a shifting
magnetic field on the guideway. The on-board superconducting magnets
are attracted and pushed by the shifting field, propelling the Maglev
vehicle.
At one end of the tank
is the integrallyattached on-board
refrigerator, which
serves to re-liquefy
the helium gas once
vaporized by regular
heat absorption and
external disturbances
during running.
Developed by RTRI, Japan. TOP SPEED:
581 Km/Hr, REPULSION Type

EMS is Attraction type whereas EDS is Repulsion type.
Guideway clearance: EMS- Upto 3/8” and EDS-Upto
4”.
Control Circuitry : EMS-on board (Power Ec. Control)
EDS-External Control.
Guideway Structure: EDS has much Complex and
expensive construction than EMS.
Magnets : EMS-electromagnets powered by
continuously charged Batteries, EDS-Superconducting
Magnets which need cooling arrangement.
TOP SPEED: EMS-450 Km/Hr, EDS-581 Km/Hr
EDS needs wheels at start but the EMS doesn’t.
