Excellent electric motor repair shop full machine shop with very capable employees can do complete motor repair from small horsepower motors to very large 2500 horsepower motors

I was at Delta Motor in 1999 in a mounting application of my company. They have changed 160 engines for us, as it was better to convert them on the spot than to send them back to Germany. The company was OK. Dave is a cool guy. They have all the engines changed and then I went to the next assembly to Egypt.

We used this shop over many years to rewind generators (motors) from 65-500 kW. While the generators came back looking nice, Delta could not handle the higher level motors. I will say, their 65-120 kW rewinds were good and run well, the 400 kWs were ok, the 500 kWs had a high failure rate. On top of this, they did not stand by their warranty on a few jobs which was most disappointing. The last generator we sent them, when they said they would not warranty it (which wasnt the first generator they refused to warranty), we asked for it back, only to find they had melted off probably a thousand or so dollars (as a guess @$3/lb.) worth of copper windings and gave it back to us bare, so not only did they not fix their generator that failed in under a year, they in essence removed our materials without reimbursement. (Also an issue because another rewind shop cant see how it was wound to be able to rewind it)Years prior, we also used them for some transformer rewinds, because they advertise they do transformer repair. They rewound our 12 kV to 480 transformers to 12 kv to 690 V, per our request. They came back looking nice, the voltages were good, but 50% of them starting leaking oil out of the various bayonet fuse holders, switches etc. within a couple years of the repair.More recently, about the same time we were having our fallout over the 500 generators, we we had one of the Delta rewound transformers minorly fail under a warranty period, they inspected it, found something wrong fixed it under warranty and returned it (small fix). We put it back online and within a few months of running it, a catastrophic failure occurred at the section of transformer they had just reworked (basically it blew up). They refused to warranty it at this point and sent us a rather large quote. When pushing for warranty coverage and investigating deeper and in speaking with employees who left Delta and solicited our business, we found that they dont even do the repairs, they had subcontracted out the work to another company!!They have good prices, but you get what you pay for. The most disappointing aspect was the lack of standing behind their product warranty. We had a good run with them on the small stuff, but they pushed to do the more expensive and larger items at our facility and they failed miserably at it, which is why we no longer do business with them. They should have said sorry, honored the warranty and let us know they only want to handle the smaller stuff, instead we had a huge falling out. We are still assessing our legal options on recovering the warranty claims for the generators, transformer and the loss of windings they melted off.
