Equivalent Circuit of an Induction Machine

| 2007| | Johnny Kennedy DT021 yr2 Group B 08/06/2011 | Investigation of the tantamount(predicate) delineate covering of an induction machine| | Investigation of the equivalent tour of duty of an generalisation form Objective: The objective of this experiment is to suss out the equivalent turn of an certainty gondola (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 facility railway car when it is drawing rated current and examine these set to their respective mensural value. Theory: The 3-phase AC (3?) Induction Motor has 2 master(prenominal) components these being the stationery Stator and the Rotor which revolves. The Induction Machine takes in electrical cogency, this Electrical energy is used to set up an alternating Electro-magnetic field of study which turns the rotor coil and the rotor produces mechanical energy, the output energy is slight than the input energy due to losses.

There is no physiological electrical familiarity 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 dedu ced by performing 2 tests on each device, th! e 2 tests performed on the Induction Machine are the No deprave mental testing and the Locked Rotor Test (the No pervert 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 thin out 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 red ink to get a full essay, order it on our website: OrderCustomPaper.com
