Which motor is used in traction system?
Traditionally, these were series-wound brushed DC motors, usually running on approximately 600 volts. The availability of high-powered semiconductors (thyristors and the IGBT) has now made practical the use of much simpler, higher-reliability AC induction motors known as asynchronous traction motors.
What is traction motor in locomotive?
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 are various types of traction motors?
The three main types of electric traction systems that exist are as follows:
- Direct Current (DC) electrification system.
- Alternating Current (AC) electrification system.
- Composite system.
How much does a traction motor cost?
These are useful motors, however, they do not offer the increased pulling power offered by AC locomotives. DC locomotives cost around $1.5 million, depending on manufacturer….AC vs. DC Current.
| Current Type | Tractive Effort | Cost |
|---|---|---|
| AC Current | 180,000 lbf | $2 million |
| DC Current | 140,000 lbf | $1.5 million |
What is meant by electric traction?
Introduction: By electric traction is meant locomotion in which the driving (or tractive) force is obtained from electric motors. It is used in electric trains, tramcars, trolley buses and diesel-electric vehicles etc.
Which motor is best for traction?
AC induction three-phase asynchronous and permanent-magnet AC synchronous motors are the two most widely used traction motors in the railway sector due to their high-power output, low maintenance cost, and increased efficiency over DC electric traction motors.
Which DC motor is used for traction?
Detailed Solution
| Motor | Application |
|---|---|
| DC series motor | Traction system, Cranes, air compressors |
| DC shunt motor | Lathe Machines, Centrifugal Pumps, Blowers, Conveyors, Weaving Machine, Spinning machines |
| DC compounded motor | Presses, Shears, Elevators, Rolling Mills |
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.
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.
Where is DC series motor used?
Series DC motors are generally used where high starting torque is required, and speed variations are possible. These types of direct connection motors are, for instance, used in the traction system, cranes, air compressors, vacuum cleaners, sewing machines, etc.
How much is a brand new locomotive?
So, How much do locomotives cost? A diesel locomotive could cost from $500,000-$2 million. While an electric locomotive could cost more than $6 million. Price depends on whether it is powered by AC or DC traction, how much horsepower it has, or what electronics it is equipped with.
Who is the manufacturer of the ASEA AEM7 locomotive?
The AEM-7 is a result of a industry-changing partnership between EMD and ASEA, in which the locomotive would be built using multiple suppliers. In 1978 EMD began production. The car-bodies were manufactured by Budd, electrical, trucks and traction motors came form ASEA, All other aspects built by EMD.
When did ABB ASEA start making electric trains?
In 1926 the company provided the electric locomotives and converter equipment for the first electric trains on the Stockholm-Gothenburg line, and in 1932 ASEA built the world’s largest naturally cooled three-phase transformer. During the 1930s, company management decided to concentrate on expanding and improving its domestic operations.
What kind of business does ASEA AB do?
ASEA Asea AB, an industrial jewel of Sweden, was created in 1883. Asea’s business was broadly defined as “the generation and application of electric power”. The company manufactured such diverse items as steam turbines for power plants and high-speed electric locomotives for passenger railroads.
When did ASEA acquire Stromberg AB in Finland?
The big step forward had been the acquisition in Finland of Strömberg AB with its 7,000 employees, which was followed in late 1987 by the acquisition of 63 percent of EB Corporation in Norway. By 1987, Asea was radically altered from a Swedish-centered company to a pan-Nordic electrical multinational.
