I have a problem that I need your help with. I have a Keling Technologies KL23HM276-30-8B Stepper motor that I need to replace (The shaft broke). I need a direct replacement, so I don't have to change the set up on the controllers, because I have no clue how to do that. I have searched for a week trying to find someone that sells this model # and can not find it. Keling Technologies now has the same model number without the M character. I contacted them, and they informed me it was the same motor, but it was at 1.8 degrees instead of something else (what does that even mean). The man I spoke with was difficult to understand. My question is will this work? Are there other manufacturers which would offer a direct replacement? What are the performance characteristics that I should look for? Please Help.
