Which motor is used in electric train in India?

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.

Which DC motor is used in electric train in India?

Nowadays the trend is toward AC motors, typically a 3-phase induction motordriven by a DC->AC inverter control.

Which engine is used in Indian Railways?

The Indian Railways primarily operates fleet of electric and diesel locomotives, along with several compressed natural gas (CNG) locomotives. Steam locomotives are operated on a few World Heritage Sites and also run occasionally as heritage trains. A locomotive is also known as a loco or more popularly as an engine.

Do trains use AC or DC?

Direct current, either directly supplied, or converted from AC onboard a train, is the most commonly used. This is because, according to railsystem.net, “DC consumes less energy compared to an AC unit for operating the same service conditions.

Which motor is used in metro train?

THREE PHASE SLIP RING INDUCTION MOTOR has been used in DELHI METRO. Dc series motor is ideal for traction but the maintenance cost of which is very high also needs the conversion and smoothening of AC voltages.IM has less maintenance,high starting torque, cheap etc.

Which motor is used in Electric train?

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.

Are diesel locomotives AC or DC?

In a diesel–electric locomotive, the diesel engine drives either an electrical DC generator (generally, less than 3,000 horsepower (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 horsepower (2,200 kW) net or more for traction), the output of which provides power to the traction …

Which fuel is used in Metro?

Metro trains run on Electricity. OverHead Equipment (OHE) wire or third rail is used for it. So directly there is no fuel required for metro train but indirectly most commonly we use coal to produce electricity in thermal power plants or nuclear energy in nuclear power plants.

In which year electric train started in India?

The first electric train ran in India with the inauguration of services between Bombay VT and Kurla Harbour on 3rd Feb 1925 on ex-GIP Railway system. The section was electrified on 1500 Volt DC.

What engines are used in train?

The diesel engine drives either an electrical DC generator (generally, less than 3,000 horsepower (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 horsepower (2,200 kW) net or more for traction), the output of which provides power to the traction motors that drive the locomotive.

IMPORTANT:  Why does an electric motor lose torque?

Which fuel is used for train?

Indian trains primarily run on electricity or diesel. Currently, around two-third of freight and more than half of passenger traffic in Indian Railways are ferried by electric traction (engines). However, electric traction accounts for just 37% of the total energy expenses of Indian Railways.

Are bullet trains electric?

Trains. Shinkansen trains are electric multiple units, offering fast acceleration, deceleration and reduced damage to the track because of the use of lighter vehicles compared to locomotives or power cars.

What is railway electrification?

A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. … Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains.

Which motor is used in crane?

Answer: As the purpose of the crane is to lift heavy load through rope or chains, so it demands a kind of motor, which has a very high starting torque to lift the load at low current. Squirrel cage induction motor has the problem of low starting torque due to low resistance.

Which current is used in railways?

Railway electrification systems using alternating current (AC) at 25 kilovolts (kV) are used worldwide, especially for high-speed rail.

What is electric traction motor?

Traction motors are powered by electricity and generate the power to rotate the wheels of the train. The turning force produced by traction motors is transmitted to the wheels via the driving gear unit and axle. Traction motors are typically mounted in the trucks where the wheels are housed.
