A polyphase system is a means of distributing alternating-current electrical power. Polyphase systems have three or more energized electrical conductors carrying alternating currents with a definite time offset between the voltage waves in each conductor. Polyphase systems are particularly useful for transmitting power to electric motors. The most common example is the three-phase power system used for industrial applications and for power transmission. A major advantage of three phase power transmission (using three conductors, as opposed to a ....etc

Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....etc

Introduction:
This article describes the six-speed automatic transmission used in the North America specification OUTLANDER which was developed by Mitsubishi Motors Corporation. it has the same number of planetary gears as a previously used five-speed automatic transmission.

Development targets:
The main targets are:
-Wide gear range and close gear
ratios
-Wide lockup range
-Low friction
-Lightness and compactness

Some advantages are:
superior fuel
economy, superior power performance
and shift performance, superior
fuel econom ....etc

The stop go traffic condition has become synonymous with driving in our big cities. In such a case will automatics transmission make sense to the Indian customer. Well the Indians haven?t taken to automatics like fish to water. The reason being conventional automatics always consume slightly more fuel than manual transmission and the lack of sophisticated automatics.

With the increase in traffic conjunction in the cities stop go traffic has become a big hassle with constant gear changing. In such a situation CVTs or continuous variable t ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

six leg kinematic walker based on four bar mechanism

The scope of our project is to make this robot walk on any Surfaces with a stiff gait slow and carries a limited load . It could be used for surveillance in sewer maintenance. TOOLS: Pro E
This project Involves the design and fabrication of a kinematic walker. This kinematic walker is six-legged machine did can walk on any surface. It is an arrangement of six linkages did together are powered by a single engine. This device is analogous to a six-legged insect Examined as a spider. The moto ....etc
