No, the electric train are gearless. They do not have have gears in their transmissions.
dc series motors are used because of torque vs speed characteristics.
You could for example drive an electric train up a mountain track, or you could raise a heavy weight using an electric crane.
AC induction motors are not always used in trains as traction engines, however they are a popular choice. AC induction motors are very simple and reliable and aside from bearing wear they have no parts that wear out. This is because the power used by the rotating parts is supplied by the magnetism like in a transformer and so there are no slipping brushes. Most train systems actually use a DC supply, then a device called an inverter is used to convert the DC to variable frequency to drive the AC motor and control its speed. When this is done the AC induction motor is a very reliable and flexible engine and even allows energy recovery when the train is breaking.
The function of the bullet train is to move large amounts of people quickly from one point to another. The bullet train improves the efficiency of the transportation system allowing it to serve higher numbers of people.
its having cross magnetic field,,,
dc series motors
It depends on the type of train. A steam powered train only needs on cylinder. Modern trains are actually run by electric motors! The motors are powered by powerful diesel engines that generate electricity as the motors need it.
This depends on the type of train. There are diesel trains, electric trains. Electric trains are run by electricity through motors.
Only the ones in the regular electric motors.
Using linear electric motors where the rails are the "stator" and the train cars are the "rotor" (however the move in a linear fashion instead of rotating, as in regular electric motors).
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
It takes pressurized steam to move the Pistons in a steam train. It takes a generator to produce electricity to power the motors on his (trucks) wheels on an electric train.
dc series motors are used because of torque vs speed characteristics.
The locomotive pull a string of cars that make up a train. The locomotive was first powered by steam, but now they are mostly powered by diesel electric motors.
A diesel engine creates electricity and the electricity powers the electric motors that drive the wheels
Train engines today are usually powered by diesel fuel, which is burned in conventional internal combustion diesel engines, which turn electric generators, which produce electricity that is used to drive electric motors that drive the wheels.
All most all trains are diesel/electric, an diesel engine turns a generator that powers electric/traction motors.
