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…
Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a…
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…
Short Time Intermittent Duty: Another class of duty for normally occurring loads is Short Time Intermittent Duty in which the load requires a constant power for a short interval of…
Electric Motor Cooling and Heating: The geometry of an Electric Motor Cooling is too complex to predict accurately the heat flow and temperature distribution. This is a difficult task. A…
Reversible Drives using Choppers: Using two quadrant choppers a reversible drive can be achieved, because this combination allows reversal of both current and voltage of the motor termiÂnals. We can…
Reversible Drive using Dual Converter: It is possible to reverse both voltage and current of the load using a dual converter. The current reversal is very fast in this case…
