Investigation of the equivalent circumference of an evocation form

Objective:
The objective of this experiment is to investigate the equivalent circuit of an certainty Machine (3? AC evocation Motor), deduce the activated and resistive elements that comprise the equivalent circuit from performing 2 tests (No lade & Locked Rotor), calculate the stator coil Current, 3? condition and Torque of the Induction Machine when it is drawing rated current and examine these set to their respective measured values.

Theory:
The 3-phase AC (3?) Induction Motor has 2 main components these being the stationery Stator and the Rotor which revolves. The Induction Machine takes in electrical energy, this Electrical energy is used to set up an alternating Electro-magnetic field of study which turns the rotor and the rotor produces mechanical energy, the output energy is slight than the input energy due to losses.



There is no physiological electrical connection between the 2 components because the Induction Machine operates by Electro Magnetic Induction, the Induction Machine shargons this principle of cognitive operation with the Transformer and therefore both Electrical devices share many of the selfsame(prenominal) characteristics and their respective equivalent circuits are almost identical, the equivalent circuits of both devices can be deduced by performing 2 tests on each device, the 2 tests performed on the Induction Machine are the No Load mental testing and the Locked Rotor Test (the No Load Test is equivalent to the Open circuit Test performed on a Transformer and the Locked Rotor Test is equivalent to the short circuit Circuit test performed on a Transformer).

No Load Test: The No Load Test on an Induction machine is run at the Rated Voltage of the Induction Machine. The values measured, recorded and used in the following calculations are |VNL |, |INL|,...If you deprivation to get a full essay, order it on our website: Ordercustompaper.com
