3 iiiiv eee i semester page load test on 3 phase induction motor aim.

Induction motor load test. The induction motor testingroutine testing or fat test is performed after completion of assembly by the manufacturer to prove that the motor has the same specification as required in the purchase order. Torque slip efficiency power factor etc. No load test is same as the open circuit test performed on the transformer.

Tests are required to check the condition of the induction motor and to get the basic idea of malfunctioning of the motor. Now a day lots of techniques and tests are available which gives the complete health card of the induction motors. Three phase induction motor load tests record the specifications of the induction motor im arrange and measure the resistance of the load rack in the same manner as in the previous experiment for 6 different readings.

During this test the motor is operated at rated voltage and frequency and normally loaded mechanically by brake and pulley arrangement from the observed data the performance can be. The no load test and the blocked rotor test are two main induction motor tests which are performed on induction motor to know the different losses power factor and efficiency of the induction motor. Csv feb 6 2015.

No load test of an induction motor no load test is an indirect method used for determining the efficiency and also to determine the circuit parameters of the equivalent circuit of the three phase induction motors. Siddhartha institute of engineering technology eee department em ii lab experiment no. The load test on induction motor is performed to compute its complete performance ie.

The open circuit test performed on the transformer. Generator the induction motor is connected to a dc. These constants are used for developing the equivalent circuit of three phase induction motor and for construction of circle diagram.

Load test on 3 phase induction motor 1. In case of loading by connecting a dc. Thus inturn an induction motor is loaded.

Therefore small current is applied to the machine due to which there is a fall in the stator impedance value and rated voltage is applied across the magnetizing branch. 1 shows the experimental set up for conducting load test on three phase induction motor using a dc. Theory of no load test of induction motor the impedance of magnetizing path of induction motor is large enough to obstruct flow of current.

From the test datas obtained on no load test and blocked rotor test of the three phase induction motor are used to determine the above mentioned constants.
