A thermocouple is the devise used extensively for measurement of the temperature of the body. It is composed of at least two metals joint together to form two junctions. One is connected to a body of known temperature, while the other is connected to a body of unknown temperature. This enables us to measure the temperature of the unknown body by comparing it to the known. Learn more about how ...

Hydrodynamic Bearings are named so because of the lubricating principle involved in the bearings. Apart from the construction that acts as the bearing, the lubrication plays a very vital role in the construction to act as a bearing. B efore we proceed to look into what a hydrodynamic bearing is, let us know about Hydrodynamic lubrication.

The Working Principle of a Compression Load Cell A load cell is a transducer that measures force, and outputs this force as an electrical signal. Most load cells use a strain gauge to detect measurements, but hydraulic and pneumatic load cells are also available.

Jun 16, 2018· Working Principle of Permanent Magnet Synchronous Motor (PMSM): The working principle of permanent magnet synchronous motor is same as that of synchronous motor. When three phase winding of stator is energized from 3 phase supply, rotating magnetic field is set up in the air gap.

Working Principle: A lightemitting diode is a twolead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

A medical ventilator (or simply ventilator in context) is a machine designed to provide mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently.. While modern ventilators are computerized machines, patients can be ventilated with a simple, handoperated bag valve mask.

Nov 15, 2019· Current Transformer: Definition, Principle, Equivalent Circuit, Errors, and Types. Updated on November 15, 2019. OSBERT JOEL C. ... The basic principle of the current transformer is the same as that of the power transformer. Like the power transformer, the current transformer also contains a primary and a secondary winding. ... Φ m = working ...

THEORY, CONSTRUCTION, AND OPERATION 1. CHAPTER 1 PRINCIPLES OF OPERATION ... standing of the principles governing the machine’s design and operation, but ... requirements in designing an electric machine is the efficient removal of these resistive losses, with the purpose of limiting the undesirable temperature rise of ...

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor.

Just like a DC Machine, a same induction machine can be used as an induction motor as well as an induction generator, without any internal generators are also called as asynchronous generators. Before starting to explain how an induction (asynchronous) generator works, I assume that you know the working principle of an induction motor.
