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.
Does Metro train have engine?
The trains have no engine line of metro trains and will be driven by a self-propulsion module sans a separate locomotive and the train can run with the speed of up to 160 km per hour, with advanced technical features for enhanced quick acceleration. The train can be driven from both sides like metro trains.
Do Metro trains use petrol?
With trains running on electricity and not using any fuel, it makes Metro an environment-friendly option.
On which fuel does Metro run?
Today, DMRC received 27 MW power from the project based in Madhya Pradesh and the same will gradually increase to 99 MW. Delhi Metro trains will now also run on solar power as the DMRC on Thursday received 27 MW power from the Madhya Pradesh-based Rewa Solar Power Project, officials said.
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.
Are train motors AC or DC?
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 electric trains AC or DC?
Most electrical trains operate by collecting current from an outside source, rather than generating it themselves. This can either form a DC third rail, or fourth rail (as in the London Underground), or overhead power lines (the most common type).
Are Metro rails electric?
And rightly so, since Metro’s trains run on 800 volts – enough to propel a packed rush-hour train at speeds of up to 70 mph through the Red Line tunnel between Hollywood/Highland and Universal City station. On subway trains, the third rail is the source of the electrical delivery system.
Do electric trains have engines?
But what are the benefits of have an electrified line? Electric lines mean that trains with heavy diesel engines are not needed. Plus, trains don’t need to carry their own fuel and fuel is supplied through the overhead cables. Thus, this means the electric trains are lighter than diesel trains.
Are trains electric?
The great majority of trains operate using an electricity supply that is external to the vehicle. To operate without an external power supply, the train must transport its own energy for propulsion. Traditionally, this was carried along in the form of coal and water (steam traction) or diesel (diesel traction).
What type of motors are used in Metro Trains?
Older metro rakes from DMRC and KMRC use DC 750 V or 550 V series motors. Newer metro systems are now using 3 phase asynchronous motors which have lesser maintaining cost. Some new metro systems are Kochi metro, Bangalore metro, Chennai metro, Mumbai metro etc.
What is the power source of a metro train?
Metro rails sets are actually train-sets, like electric multiple units (EMUs). The power is produced in several/all of the compartments, there is no designated engine. For the specifications, different metro rail systems in India use different systems for traction, a comparison is available here: Rapid transit in India.
Which voltage is used for Main Line trains in India?
In India 1500 V DC and 25 kV AC, 50 Hz, is used for main line trains. The 1500 V DC overhead system (negative earth, positive catenary) is used around Mumbai. The Mumbai region is the last bastion of 1500 V DC electrified lines on Indian Railways.
What type of motors are used in metro rakes?
Older metro rakes from DMRC and KMRC use DC 750 V or 550 V series motors. Newer metro systems are now using 3 phase asynchronous motors which have lesser maintaining cost.
