How does a traction motor work?
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.
Which motor is used for traction work?
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 electrical drives PDF?
Electrical drives convert electrical energy into mechanical energy and act as a intermediary between electrical supply systems, various energy sources, driven machines and the energy consumer.
How does a DC traction motor work?
The DC motor works because, simply put, when a current is passed through the motor circuit, there is a reaction between the current in the field and the current in the armature which causes the armature to turn. The armature and the field are connected in series and the whole motor is referred to as “series wound”.
What is stepper motor PDF?
Stepper Motor. A stepper motor, also known as step motor or stepping motor is a brushless DC special. electric motor that divides a full rotation into a number of equal steps (move in discrete steps). With. a computer controlled stepping you can attain very precise positioning and speed regulator.
What is the principle of universal motor?
Working Principle of Universal Motor: When current flows in the field winding, it produces a magnetic field. The same current also flows from the armature conductors. When a current carrying conductor is placed in an electromagnetic field, it experiences a mechanical force.
