As shown below, the indicated terminal matrix (blue lines) shows the way the windings of a 3 phase motor should be tested with an ohmmeter: 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.

How To Check 3 Phase Motor Winding With Multimeter Wiring Work Step 1: inspect the 3 phase motor. before starting the winding check process, inspect the motor for any visible damages or signs of wear and tear. if you find any, consider repairing or replacing the motor. to prevent any damage to both you and your multimeter, ensure that the 3 phase motor is powered down before you start the winding check. 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. 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. Place both instrument test leads to ground and verify a solid connection to ground of the instrument lead. measure the insulation resistance to ground (irg). this value should be zero megohm (mΩ). if any value other than zero displays, reconnect the test leads to ground and retest until a zero reading is obtained.
