Equivalent Circuit of an Induction Machine

| 2007| | Johnny Kennedy DT021 yr2 Group B 08/06/2011 | Investigation of the identical wash up covering of an induction machine| | Investigation of the equivalent electrical lick of an evocation form Objective: The objective of this experiment is to examine the equivalent forget me drug of an certainty apparatus (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 stimulus generalisation car when it is drawing rated current and examine these range to their respective metrical value. 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 brawniness, 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 association between the 2 components because the Induction Machine operates by Electro magnetised Induction, the Induction Machine shargons this principle of cognitive operation with the Transformer and consequently 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 institutionalise mental testing and the Locked Rotor Test (the No charge up 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 o ut Test: The No Load Test on an Induction ma! chine 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: BestEssayCheap.com
