Which motor is most suitable for electric traction?

Many single phase ac motors have been developed for traction purposes but only compensated series type commutator motor is found to be best suited for traction. Single phase induction motors have been abandoned as they are not capable of developing high starting torque.

Which motor is used in electric traction?

The motors used are induction or asynchronous motors designed to have characteristics suitable for traction. The speed and torque of the motor are controlled by varying the frequency, voltage and current applied to the stator coils. Motors for a typical locomotive would be in the range 400 to 600 kW.

Which motor is preferred in electric traction in India?

Indian railway traction system uses 1.5 kV DC around Bombay and 25Kv ac is used in rest of the country.

Which DC motor is used in electric train?

Today’s advanced electric locomotives use brushless three-phase AC induction motors. These polyphase machines are powered from GTO-, IGCT- or IGBT-based inverters. The cost of electronic devices in a modern locomotive can be up to 50% of the cost of the vehicle.

Do trains run on AC or DC?

AC versus DC for mainlines

The majority of modern electrification systems take AC energy from a power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors.

Do electric trains have engines?

Instead of a tank of diesel and an engine, the train has a tank of hydrogen and a fuel cell that combines the hydrogen with oxygen from the air, without combustion. With the only emission being water, the fuel cells provide power and have zero emissions.

Which is the fastest train in the world?

China debuts world’s fastest train

  • (CNN) — A maglev bullet train that can reach speeds of 600 kilometers per hour (373 miles per hour) has made its debut in Qingdao, China.
  • Developed by the state-owned China Railway Rolling Stock Corporation, it’s considered the world’s fastest train.

Which motor is used in tramway?

Dc motor (Ma) and induction motor (Mc) are currently manufactured and used in 105 N tram drive, their parameters are available. Dc motor (Mb), brushless motor (Me) and slip-ring motor (Md) pa- rameters have been determined by analysis.
