In this project, we designed a three phase four pole squirrel cage induction motor of fractional horsepower and 1400 rpm speed. We used an old induction motor for the casing and other bulk parts and re-winded that motor as per our requirements of design. This project was associated with Electrical Machineries Laboratory and was done as an attempt to understand the fundamentals of electric machineries and how the construction of such machines changes with our requirements. The project also made us aware of the market conditions of different types of materials used in various AC machines. After design and rewiring, we also analyzed the torque speed characteristics of the motor and verified it using MATLAB software as per our theoretical prediction.

In this project, we designed a temperature-controlled fan speed controller using analog circuitry system incorporating filters and NTC (Negative Temperature Coefficient) resistors to sense temperature changes and a PWM controller to control the fan speed. The project was focused on using household power supply system to power up an op-amp to control the speed of a fan through voltage regulation. While calibrating fan speed, CPU performance with respect to temperature was considered.

This project is associated with Numerical Analysis laboratory where I use Navier-Stokes equation to develop a basic simulation model showcasing the dynamics of shallow water surfaces. It focuses on the behavior of water at the surface level, providing a visual representation for educational and preliminary research purposes. The project involves developing a simplified computational model, implementing it into a user-friendly software with adjustable parameters, and generating visual outputs to observe and analyze the effects of different inputs. The outcome will be a simple yet engaging simulation tool, serving as an introductory platform for understanding shallow water surface behavior and laying the groundwork for further exploration.
