      INTRODUCTION OF TRANSDUCERS  A transducer is a device that convert one form of energy to other form. It converts the measurand to a usable electrical signal.   In other word it is a device that is capable of converting the physical quantity into a proportional electrical quantity such as voltage or current. BLOCK DIAGRAM OF TRANSDUCERS • Transducer contains two parts that are closely related to each other i.e. the sensing element and transduction element.  • The sensing element is called as the sensor. It is device producing measurable response to change in physical conditions.  • The transduction element convert the sensor output to suitable electrical form. CHARACTERISTICS OF TRANSDUCERS 1. Ruggedness  2. Linearity  3. Repeatability  4. Accuracy  5. High stabilityand reliability  6. Speed of response  7. Sensitivity  8. Small size TRANSDUCERS SELECTION FACT...

Induction Motor | Working Principle | Types of Induction Motor One of the most common electrical motor used in most applications which is known as  induction motor . This motor is also called as asynchronous motor because it runs at a speed less than its synchronous speed. Here we need to define what is synchronous speed. Synchronous speed is the speed of rotation of the magnetic field in a rotary machine and it depends upon the frequency and number poles of the machine. An  induction motor  always runs at a speed less than synchronous speed because the rotating magnetic field which is produced in the stator will generate flux in the rotor which will make the rotor to rotate, but due to the lagging of flux current in the rotor with flux current in the stator, the rotor will never reach to its rotating magnetic field speed i.e. the synchronous speed. There are basically two  types of induction motor ...
