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.

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

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.

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

When ready, follow the steps below to learn how to measure 3-phase current. Step-1: Prepare for the test: Set the multimeter up to measure amperes and adjust it to the appropriate ampere range for the motor based on the specifications on the nameplate. To avoid electric shock, wear rubber hands during the test.

Connection problems: Connection problems create current imbalances between the phases of a three-phase motor, causing excessive heating and premature insulation failure. Opens: Opens occur when a conductor or conductors break or separate. This may prevent the motor from starting or cause it to run in a single-phase condition, which draws excess current, overheating of the motor and premature

1. Fist make sure that the three-phase power voltages supplied to the motor are the proper voltage and balanced. Check the resistance U1 to V1, V1 to W1 and W1 to U1. The resistances should be very close to being equal. Do the same for U2, V2 and W2.

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.

Multimeter test method is given below mentioned. Three phase motor has three windings, one is R phase, second is Y phase and third is B phase. Firstly, power connection is disconnected from connection plate then motor can be tested below mentioned procedures. Multimeter is a test instruments which is used in commonly for winding coil insulation

Set your multimeter to Ohms. Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a zero reading or any continuity reading, you have either a motor problem or a cable problem.

Winding problems that are identified should be documented. A history of the plant's motor problems (on computer software) will point out problem areas that ran be improved, or even eliminated. These winding problems may be found in a three-phase motor: Shorted turns; Ground (winding shorted to frame) Phase-to-phase short; Open winding

Switch on your volt ohmmeter to ohms. Now connect the leads from your motor to each power connection. See to it that each reading shows only either infinite ohms or OL on the ohmmeter. However, it the reading is not OL, then it means that the motor is not good, in which case you may have to replace it. In order to test a 3-phase motor further

Example: If a 230V motor is being tested, use the 500V setting on the megohmmeter. Place one meter lead on the ground terminal or wire and place the other meter lead on one of the phase wires or terminals. Press TEST on the meghometer . A very high resistance reading ( generally greater than 10 megaohms) will indicate the motor insulation is good.

When it comes to maintaining and troubleshooting 3-phase motors, having the right tools and knowledge is crucial. Multimeters. One of the most common instruments used to diagnose motors is a multimeter. Multimeters allow you to measure crucial electrical parameters such as voltage, current, and resistance across the motor's windings.

Assessing the condition of a three-phase motor relies on early indication of the insulation breakdown. To do this, MCA™ uses low-voltage AC signals to exercise the winding insulation system to determine when the winding insulation begins to undergo the chemical changes that occur as the insulation begins to degrade.
