Week-7 Challenge: DC Motor Control

The powertrain of an Electric Vehicle (EV) consists of an electric drive system with a battery serving as an energy buffer. Often there is only one electric machine, typically of three phase AC type, connected to the wheel shaft via a gearbox and a differential. However some applications may utilize several electric machines,…

1. Search and list out the total weights of various types of aircrafts In order to well understand the impact of weight and balance on the stability and maneuverability of the aircraft, it is worth getting back to the forces that apply to the aircraft, and more specifically to focus on the vertical ones. There are two…

Question-1 A driving cycle commonly represents a set of vehicle speed points versus time. It is used to assess fuel consumption and pollutants emissions of a vehicle. For this challenge, the self-defined drive cycle ‘Sanjay Drive Cycle’ is considered to calculate the braking energy required. Prior…
