The mechanical Engineering category in Krazytech.com hosts technical presentation topics for college students, technical topics for presentation for Mechanical Engineering, Automobile, robotics, nontechnical topics etc.

Structure and types of carbon nanotubes

Carbon Nanotubes

Carbon nanotubes, long thin cylinders of carbon, were discovered in 1991 by Iijima. Carbon nanotubes (CNTs) are allotropes of carbon which are members of the fullerene structural family, which also includes the spherical buckyballs.

Rapid Prototyping Techniques

Rapid Prototyping

The term “rapid prototyping(RP)” refers to a class of technologies that can automatically construct physical models from Computer-Aided Design (CAD) data. It is also called “Desktop Manufacturing or Freeform Fabrication”.

Ultrasonic Motor

Ultrasonic Motor

An ultrasonic motor is a type of electric motor formed from the ultrasonic vibration of a component, the stator, placed against another, the rotor or slider depending on the scheme of operation (rotation or linear translation). Piezoelectric ultrasonic motors are a new type of actuator. They are characterized by high torque at low rotational speed, simple mechanical design and good controllability. They also provide a high holding torque even if no power is applied.

Super Efficient motors

Super Efficient Motors:Techanical Overview

Power scenario in the country calls for energy crisis management. Industrialization and growth in population is creating a void between demand and supply, and this void is deepening day by day. The generating cost is increasing day by day & the power tariffs are on the rise. Unless the above crises are properly managed power scenario will be bleak. There is a capital investment that can repay many times its original value over the next 20 years. At the same time, it can improve equipment reliability. The investment is straightforward: install electric motors having the highest electrical energy efficiency commensurate with your needs. Energy-efficient motors pay for themselves in a few years or sometimes even a few months, after which they will continue to pile up savings worth many times their purchase cost for as long as they remain in service.
