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 resistance d ....etc [:=Read Full Message Here=:]

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 [:=Read Full Message Here=:]

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 [:=Read Full Message Here=:]

Variable Voltage And Variable Frequency drives Presented By: P.NATARAJU S.E.V.S.RAGHU VARMA 3rd year E.E.E. 3rd year E.E.E. 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 [:=Read Full Message Here=:]

Title: Sensorless variable-speed controller for fixed-speed wind power generator Page Link: Sensorless variable-speed controller for fixed-speed wind power generator - Posted By: computer science crazy Created at: Monday 22nd of September 2008 01:54:30 AM	controller a, wind generator ametek89## sbi chech status check book, power generator hire perth, speed camera databasevehicles, variable gear, variable speed mechanism transmission, speed bump,
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 [:=Read Full Message Here=:]
