ABSTRACT
Continuously Variable Transmissions based on belts, pulleys, cones, discs, collectively friction transmissions, share many of the disadvantages of conventional hydraulic transmissions. CVTs require clutching mechanisms, hydraulic pumps to compress V belts between adjustable pulleys, and all have ablative belts, n ....etc

VARIABLE SPEED DC MOTOR DRIVE


DC MOTOR THEORY:
Inducing a Force on a Conductor.
There are two conditions which are necessary to produce a force on a conductor:
i. The conductor must be carrying current.
ii. The conductor must be within a magnetic field.
When these two conditions exist, a force will be applied to the conductor, which
will attempt to move the conductor in a direction perpendicular to the magnetic
field. This is the basic theory by which all DC motors operate.

Numerical Solution of radial heat conduction in an infinitely long cylinder



INTRODUCTION

Conduction problems can be solved in various methods but in this paper we have solved a simple radial heat conduction problem and compared the results obtained in each method (FDM, FVM, FEM) for different meshes. We have also supported our solution with sensible reasons.
This problem explains the temperature distribution on the radial direction of the pipe. The practical application is i ....etc

Variable DC power supply is one of the projects that each student of the electronics should build. Build your own power supply is fun and use it throughout your building projects is the reward of your success. This project uses a transformer to reduce the incoming AC voltage to 12.5V AC.

This circuit is designed for 240VAC input voltage. If 110VAC is necessary, a power transformer 110 / 12.5 should be used. Buck of AC voltage is then rectified by a diode bridge. The rectified DC voltage is smoothed by means of an electrolytic capacitor 2 200uF ....etc

Variable Frequency Drives

Introduction
Variable Frequency Drives are devices which control the speed of alternating current(AC) electric motors by controlling the frequency of the supply voltage of the motor. Motor-driven systems are designed to handle peak loads. If the system is running at a reduced load for some period of time, it will lead to energy inefficiency. With Variable frequency drives and the ability to adjust the speed of the motor, enables you to match the motor output to load requirement thus resul ....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
