Last time gearbox oil changed? Grease required on thrust bearing? Motor clipping fields because the bearings are worn out? Loose electrical connections to the motor? Assuming the oil level has been maintained, and the oil's been changed as per the maintainence schedule, and the motor isn't a problem, sounds like a thrust bearing going out, or the thrust bearing nut and lock worked its way loose. The other liklihood would be that the coupling device (usually has the brake drum on it) may have come loose or sheared the woodruff key(s) or the drum locknut came loose. Seeing the motor turn while the drum doesn't is quite disconcerting. Either way, looking is a lot cheaper than having an accident. I don't have any experience with Indian equipment, but most gearmotors are pretty much similar in purpose and implementation. Good Luck. S.
