Got this 3 phase motor. Saw the small plugs in the picture above the bearings, so popped them off and put several drops of oil in. Spun super easy, but nothing was dripping out the bottom hole. Put quite a bit more oil in. Still nothing. poked my Allen wrench in the holes and discovered grease in it that was stopping the oil from running out the bottom. Then I noticed on the nameplate it specifies to use grease...
1. I put a whole lotta drops of oil in. It was eventually coming out around the shaft. Will this have messed something up? Gotten on the windings? Its not TEFC, so I expected some to come out the venting
2. What should I do now? Can I just thread a grease fitting in it and use this from here forward? I was thinking of putting grease fittings on the top and pumping until it came out the bottom?
3. Kind of unrelated: The bandsaw I just bought has a 5hp 3phase motor. It is TEFC and has grease fittings for front and back bearings. Since the motor is totally enclosed, where does the grease go? Seems like it would eventually fill the whole inside of the motor...
