![]() ![]() First of all, you need to understand how the coils are connected with the six motor leads that exist in the electrical connection box. Two or more coils short-circuited with each other (current leaking from one coil to another coil)Īll of the above problems can be detected with a simple Ohm-meter.Leaking coil to ground (current leaking from one coil to ground/neutral). ![]() Short-circuited coil (less than normal or zero coil resistance). ![]() There are basically 4 problems that the motor windings can suffer from: If someone works with AC 3-phase motors, then it is important to know how to connect these motors in Star and Delta connection, and how to detect an electrical problem. It is called squirrel-cage, because it's rotor looks like the exercising wheel found in squirrel or hamster cages.Ī typical 3-phase squirrel-cage motor has six connection leads in the electrical connection box for the three coils. The most common type though is the -so called- squirrel cage rotor. The rotor of a squirrel-cage motorThere are several different AC motor types, each one with different operating and mechanical characteristics. ![]()
