CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same spe ....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 ....etc

SPEED CONTROL OF SYNCHRONOUS MOTOR BY USING VARIABLE FREQUENCY DRIVES



ABSTRACT
:

A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resista ....etc

STEPLESS SPEED DRIVES & CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
INTRODUCTION

A continuously variable transmission (CVT) is a transmission that can change steplessly through an infinite number of effective gear ratios between maximum and minimum values.
This contrasts with other mechanical transmissions that offer a fixed number of gear ratios.
The flexibility of a CVT allows the driving shaft to maintain a constant angular velocity over a range of output velocities.
ADVANTAGES
This can provide better ef ....etc

Discrete Variable Frequency Soft Starting on DSP-based Voltage Controller-Fed IM Drive
Abstract

GThyristorized soft starters are being used as inductionmotor starters in fan or pump drives, ere, the principleofwhich is based on the control of variable voltage and constantfrequency. One ofthe demerits of the soft starters is that a smallreduction in voltage produces a considerable drop in electromagnetictorque, which may cause the motor with loads failureto start. A new control strategy is proposed to improve electromagnetictorque at st ....etc

Every kW of energy saved is as good as same amount of energy generated. Such is the scarcity of energy in India. Energy can be saved by using Variable Speed Drives (VSD) for applications like Pumps and Fans. Employing conventional techniques, which uses a motor running at full speed and flow pressure being created by throttle valve, a lot of energy is wasted due to electric, thermal and mechanical losses. By replacing conventional arrangement with AC drives, tremendous amount of energy can be saved. However, traditional approach to flow control ....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 cag ....etc
