What is a traction motor used for?
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.
What are the different features of traction motor?
General Features of Traction Motor & Speed – Torque Characteristic of D.C. Motor. – Good commutation under rapid fluctuations of supply voltage. – Robustness and ability to withstand continuous vibrations. No type of motor completely fulfills all these requirements.
What are the two types of motors?
There are two obvious types of electric motors as determined by input voltage: AC (Alternating Current) or DC (Direct Current). While AC motors use alternating current to power a series of wound coils, DC motors use direct current to power either carbon brushes or electrical commutation.
What type of DC motor is used in traction?
4.6
| 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 |
| Stepper motor | 3D printing equipment, Small robotics, CNC milling machines |
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.
Which motor is suitable for 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.
How many different motors are there?
Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.
Can a single phase motor be used for traction?
What is a traction motor in a locomotive?
Traction motor is one form of prime mover (primary equipment which moves the vehicle) in a locomotive (colloquial name: Train engine). Traction motor serves the same purpose a petrol engine does to your motor bike. A typical traction motor used in trains is a 3 phase squirrel cage induction motor with variable voltage variable frequency control.
What is a torquetraction motor?
Traction motor is a type of electric motor used for propulsion of a vehicle. It is used to make rotation torque on a machine and in electrically powered rail vehicles such as electric multiple units and electric locomotives. They are also used in electric vehicles such as electric milk floats, elevators and conveyors.
What is the difference between ‘motor’ and ‘engine’?
“The etymologies of ‘motor’ and ‘engine’ reflect the way language evolves to represent what’s happening in the world,” says MIT Literature Professor Mary Fuller. The Oxford English Dictionary defines “motor” as a machine that supplies motive power for a vehicle or other device with moving parts.
Are DC motors different from other electric motors?
They aren’t any different in principle from other electric motors, but with the old DC types you got field windings rather than a permanent magnet and they were wired in series with the armature: At low speed you get a high torque to get your vehicle moving and at higher speed you get a lower torque.
