Stepper Motors ??

Hello,

I've recently bought second hand old Std Colors & Spots, they are in a very bad shape , not used since 2 years probably, but for what i paid it was okay .. anyway i started the mission of bringing them back to life .. i have good experience with Robe machines , but not high end , but i found that they are easier to clean and maintain ... but one problem is that i think due to the long time of inactivity 95% of the wheels Motors are stuck , so i started taking them out cleaning them and oil spraying them , some of them worked fine , but some are very weak and cant rotate the wheels or close iris , or whatever is their job .. so i just want an expert opinion , could the driver be the issue , because i'm trying to find the cheapest solution , i dont want to end up buying new motor (FINANCIAL CRISES) 10 motors per head , 60 Heads ... 600 motors .... u do the math ... so any help would be appreciated ...

Thank You

  • Okay,
    I did some research and i found that openning a stepper motor is a BAD exercise because they tend to loose magnetic flux,
    so if someone doesn't help me out here i'm going to spend (15000 + shipping + customs) on motors only, not to mention other spare parts...
    i found some web sites selling stepper motors but i can't figure out the correct number , Jeepers said its 17pm-k310-*** but going through the minebea catalog i only got to 17pm-k the rest is different ,

    Also another question, will the new motors lower the noise of operating the heads, because its generating an awful load noise, and if its not the motors how can i make it Shut-Up :)
