Why Diesel Locomotive uses Electric Motor to Drive Wheels?

For Cars, Trucks, Buses, Trains, and even Ships, the main engineering requirement is that they all need a certain torque at a certain speed at a given instant of time. The Petrol or Diesel Engine is not able to provide that required torque at a particular speed; it has different Torque/Speed Characteristics. The need is … Read more Why Diesel Locomotive uses Electric Motor to Drive Wheels?

Brushless Excitation System

Brushless Excitation System is a technology for providing the field current to the Synchronous Generator without using Slip Ring and Carbon Brushes. As this method of Excitation i.e. Brushless Excitation System do not use Carbon Brushes, therefore the losses because of contact resistance of carbon brushes is eliminated. Also, in case of initial start up … Read more Brushless Excitation System
