How To Test 3 Phase Motor With Multimeter Youtube 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. 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.

3 Phase Motor Testing With Multimeter Series Bulb Youtube Test your winding condition by testing these connections: t1 to t3. t2 to t3. t1 to t2. the reading should be between 0.3 to 2 ohms. if it is zero, there is a short. if it is over 2 ohms or infinite, there is an open. users can also dry the connector and retest to possibly get more accurate results. Test your winding condition by testing these connections: t1 to t3. t2 to t3. t1 to t2. the reading should be between 0.3 to 2 ohms. if it is 0, there is a short. if it is over 2 ohms or infinite, there is an open. you can also dry the connector and retest to possibly get more accurate results. check the inserts for burn marks and cables for wear. Most, if not all our motors only have 3 leads coming out of the connection box. the megger test is checking the condition of the ground wall insulation of the motor. we also check the phase to phase resistance reading and are looking for no more than a 10% difference max. Use a multimeter or an ohmmeter to test the voltage of the electric motor. if there is no resistance or the resistance is uneven, the motor is likely faulty. check the bearings to make sure they can spin freely. if they can’t, lubricate them. look on the outside of the motor for other potential problems, like holes or smoke points.

Step 3: test each winding with a multimeter. using the red and black probes, start testing each winding of the 3 phase motor. if the multimeter reads between 50 and 200 ohms, it indicates that your winding is in good condition. to ensure a proper check on all internal connections of each phase, use an ohmmeter and check the internal connections. 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.
