How many traction motors does a locomotive have?
How many traction motors does a locomotive have?
A modern locomotive is a hybrid. The diesel doesn’t drive the train; it cranks an alternator, which powers the six huge electric traction motors that actually turn the locomotive’s wheels. Each motor is set transversely between a pair of drive wheels.
Which motors are used in traction?
List of electric motors used for traction: 1. DC Series Motor 2. DC Shunt Motor 3….Linear Induction Motor.
- DC Series Motor:
- DC Shunt Motor:
- AC Series Motor:
- Three Phase Induction Motor:
- Linear Induction Motor:
What is a traction motor on a train?
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.
What is the purpose of traction motor?
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, elevators or electric multiple unit.
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 …
How much torque does a diesel locomotive have?
Generally, how much torque does a train engine have? – Quora. Ok a 710–16 2 stroke EMD makes about 4600 HP at 900 rpm’s. HP = (T * RPM)/5252 si solving for torque is gonna give you 26,843 ft-lbs of torque! That’s a lot of torque.
Are locomotives AC or DC?
Rectifier locomotives, which used AC power transmission and DC motors, were common, though DC commutators had problems both in starting and at low velocities. Today’s advanced electric locomotives use brushless three-phase AC induction motors.
How does a locomotive get traction?
All train cars have roller bearings on their axles, these bearings reduce friction which makes roll easy. The locomotive starts to move using sand if the wheels slip and that gives them traction. (If you would take a piece of sandpaper and rub it on a piece of steel you could feel it.)

Which motor is suitable in locomotives?
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.
What is the horsepower of a diesel locomotive?
How many horsepower is a diesel locomotive? A locomotive’s diesel engine is connected to an electric generator that is either DC or AC. In either case, the power produced is around 3,200 horsepower. The generator uses this power to convert it into a massive amount of current, approximately 4,700 amperes.
How many cars can one locomotive pull?
Depending on track gradient and other constraints such as the lengths of passing loops, loading and discharge loops and sidings, these trains can vary from 40 to 46 wagons. So each loco can pull 20 to 23 fully loaded wagons in typical operating conditions.
Why are diesel electric used on locomotives?
Diesel Locomotives use electricityto drive forward motion despite the name ‘diesel’. A large diesel engine turns a shaft that drives a generator which makes electricity. This electrical energy powers large electric motors at the wheels called ‘traction motors’.
What is a diesel electric loco?
A diesel electric locomotive is the most common type of locomotive, or train engine, currently in use on railroads around the world. In this type of locomotive, a diesel engine provides power to an electric generator.
What is a diesel electric locomotive?
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotive have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combusition locomotives and railcars used kerosene and gasoline as their fuel.
How do diesel electric locomotives work?
The engine in the diesel electric locomotive provides power to an electric generator. In this way, the locomotive provides electricity to separate motors that move the locomotive’s wheels. These are called traction motors. The traction motors are located inside the locomotive, and move the axles connected to the locomotive’s wheels.
