ELECTRIC TRACTION SYSTEMS
[attachment=38629]
MOTIVATION
Sheer size and roaring sound.
Use of electronics to bring down distance and time.
A fascination for electrical students
- Use of traction motors
- Speed Control
- Braking
TOPICS TO BE DISCUSSED
Traction system, its classification and nomenclature.
Power Supply in Electric Traction (AC and DC systems).
Traction motors used.
Control of traction motors.
Braking.
INTRODUCTION
Traction - locomotion on the rails (driving force - steam or electric drive)
Classification of Traction Systems:
> Non-Electric
> Electric
- receive electricity externally
- self contained locomotives
ADVANCED TRACTION SYSTEMS
Multiple Unit Traction System (EMU, DMU)
Driving force – from multiple units
EMU – suburban railway transport
Rheostatic Control
CONCLUSION
Advanced technologies – Magnetic Levitation used for ultra high speed trains
Electric traction – economical, easy and safe
