Usually wet motors will dry out if heated. What's up with this motor/rotary phase converter? It's been on the heater for four days and hasn't improved.
Just scratching my head on how problems could "appear". Test runs were fine, but done some time ago after i thoroughly cleaned it and put new bearings in.
Run some air through it heat it up take it apart and grease the bearings and clean up any rust on the armature and clean up the brushes and you should be fine
What are the meggar readings? 100+ meg ohms? Get the motor off the floor Clearly it’s not shorted. Check bearings Take the rotor out and clean the stator if meggar reading hasn’t come up in 4-5 days My 2 cents
At the very least take it apart and service it.what you can do when you have it apart is blow compressed air through the windings. Then spray WD-40 on the windings to move the water deep inside the windings. You definitely will have to replace the bearings because they are probably shot.
I’m not familiar with phase converters, but if it’s at all like an electric motor, the bearing lubricants and electrical contacts may be fouled up, and need cleaning. After a flood at my house, I had to replace some outlets and switches because they had dried mud in them. I’ve also had to replace some can size capacitors several times from age.
A rotary phase converter is basically a three phase motor running with no load. It generates an artificial third phase from the two single phase legs. This is a 30hp Baldor, i put in new bearings. Three phase motors have no contacts, very simple.
You may need to have a fan blowing through the phase converter to move the moisture that has built up in it. Heat alone will not remove the moisture you need airflow.
