Background: I have been dealing with a company in Turkey for some time. The last time I purchased small lathe machines the motors attached to them were 220v single phase. Over the years the motors (50hz) have gotten worse (slower rpm) probably due to the electric supply being 60hz. I had a licensed electrician do the wiring for them and spoke to him about this issue, he wasn't much help and didn't offer any solutions. This is not my field of work so I have been using them while they degrade with the passage of time. I intend to replace them soon with motors from the USA.
Current situaion: I needed more of the lathe machines so I spoke to them about the 220v 50hz motors not working well here. Their recommendation was to use 380v 3 phase motors and suggested I would not have a problem with the hertz if I went that route. I was hesitant but it's not easy talking to the company because they do not speak English and their translator doesn't always understand what I say. So, fast forward, I have the machines now and tried to get them running. The problem is that they run very slowly. I can stop the motor shaft from spinning with my bare hands. I have gotten in touch with the company and asked them for help on the matter. Due to the time difference, they will get back to me tomorrow. I also contacted the motor manufacturer for advice and I am waiting on that end as well. It took over a year for me to get these machines so the person I had hired to do the wiring is not immediately available either.
I am attaching pictures of the motor tag and the setup. If anyone can point me in the right direction, the help is appreciated. I am trying to better understand what the problem is. If it is out of my hand, I will wait for my electrician and the company to get back to me.
