Types of Steel Rolling Mills: Types of Steel Rolling Mills are either hot rolled or cold rolled. These may be either reversing type or continuous type. The motors used for…
Control of AC Motors Torque Control: From the foregoing discussion for Control of AC Motors Torque Control it is clear that the motors used for textile applications must have high starting…
Introduction Control Techniques in Electric Drives: An electric drive is a well established industrial drive as it has several adÂvantages and special features. Its Control Techniques consists in starting, speed…
Synchronous Speed on Variable Frequency Supply: As has already been discussed, the speed of a synchronous motor can be varied by supply frequency variation similar to an induction motor. The…
Synchronous Motor Drives: Variable frequency drives employing synchronous motor are receiving considÂerable interest, and are even becoming competitors to both induction motors and dc motors. These are popular as drives…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
Static Scherbius Drive: The main limitation of the Kraemer drive discussed is the operation at sub-synchronous range due to diode rectifier. Super synchronous speeds can be achieved if the power…
Speed Control Using Slip Energy Recovery Schemes: The foregoing discussion makes it very clear that the methods of voltage control and rotor resistance control have poor efficiency, particularly at low…
