How To Test 3 Phase Motor Induction Motor Testing By Using Remove cable termination cover using a screwdriver or socket. disconnect cable connections from the motor and mark them up if they are not already marked. now test phase to phase (u to v, u to w, and v to w). your meter should beep (dependant on which multimeter you are using) or display a connection between phases. Check the connection bar for terminal (u, v, and w). for three phase motors, connection type is either star (y) or delta. ac motor winding continuity test. using a multimeter, check the continuity of motor winding from phase to phase ( u to v, v to w , w to u ).each phase to phase must have a continuity if winding is ok.
How To Check 3 Phase Induction Motor By Using Multimeter Motor The first thing to do before testing the windings of the motor is to remove the links linking terminals w2u2v2 and the disconnect the motor from supply (l1, l2, l3). a multimeter terminals placed across this matrix of terminals will indicate the following readings for a good 3 phase motor: (a) terminals w1w2, u1u2, v1v2 will indicate continuity. Example 15 1: following data is taken from no load, locked rotor, and dc tests of a 3 phase, wye connected 40 hp, 60 hz, 460 v, induction motor with a rated current of 57.8 a. the locked rotor test is made at 15 hz to minimize the errors due to saturation and skin effects. determine the motor parameters and the total core, friction and windage. Three phase windings are donated as u, v and w that are mentioned on terminal plate as u1, v1, w1, and w2, u2, v2. first we will have to test r and y phase. test lamp a points is connected r phase and b phase is connected with y phase then the power supply is applied. if the lamp is glowing then r and y coil is short. Tests of polyphase induction motors and generators are covered. keywords: acceptance and performance testing, generators, induction, machines, motors, polyphase authorized licensed use limited to: iowa state university. downloaded on march 27,2012 at 23:32:28 utc from ieee xplore. restrictions apply.

Learn how to test a 3 phase induction motor using just a multimeter. in this video, you will discover the step by step process of testing an induction motor. Pph = pcu pc pfw = i12(r1 r0) pfw . thus: r0 = [pph − pfw] i1 2 r1 x0 = │zin│2 − (r1 r0)2 − x1. assuming that phase power pph, phase voltage v1, and phase current i1 are measured and that friction and windage loss pfw has been obtained as shown in figure 14, r0 and x0 can also be calculated for the motor from the no load.
