Hello again, this week I will test as an induction motor at low revs, I am going to wait a bit, to see if Marty gets any response from the manufacturer. But at 50Hz it would have to turn at 1500 RPM if the motor is 4 poles, with the formula set before I think that's the case, correct me.

Good Ashesman, it is crazy what I am going to expose but I do not know, if the motor were made of magnets, if I bring a simple compass closer I could know if there are magnets with the movement of the compass needle, do you think it would work, or is it a Madness as I say, I do not know.

ashesman, thank you for stepping into help out. Nice to see you have the background to help. It is tough when you can't actually be there and rely on the information being provided. We do the best we can do. Marty Thanks. Just trying to return the favor for all the people that help me! Its a long s...

Ok, so now that I can read the motor name plate... It has frequency and RPM ratings. Using the formula poles = 120 x f / RPM you can see that it is a four pole motor. 272 hz at 8000 RPM is 4 poles. Actually, it does not line up exactly. 4 poles at 272 hz is 8160 RPM. That suggests it is rated with ...

Good, at the end this weekend the engine has moved after 30 years of sleeping, it is very exciting but I do not know if I did it well or badly, I was touching several parameters at very low revs, but when trying to enter parameters I got different things to the manual and I realized that the manual ...

Hello again, tomorrow I am going to try to move the supposedly permanent magnet motor, but I have a question with the expansion card of the drive, I don't know which one to order for the encoder that comes with the motor, or find another encoder to make it better, to put a photo of the manual, becau...

Ok and thanks for helping me, this weekend I will connect the variator, first I will check the factory configuration that surely comes for an induction motor, I will try to read the manual to see how many parameters I have to change for a permanent magnet motor, and I will try to control it with a p...

Hello again, the current is low 10 mv because the spin was slow, when it spun faster the current shot up and I thought it was easier to make a slow reading that's why the voltage is so small. I do not know if I can do something with the little data on the motor plate, I do not know the poles of the ...
