Good Day,
I'm working on a project (Home Hobby) that require Stepper motors.
Some of my requirements:
- Torque: 1000 oz/in minimum
- bipolar parallel
- Motors rated for minimum of 72 Volts
I looked and found that this falls in the NEMA 34. And begin looking for a motor that fits my requirements. Of which I found it. It was a KL34-8N-1000 See below. I began designing for NEMA 34 mounting brackets.
NEMA34 Hybrid Servo Motor,
- KL34-8N-1000,
- 1/2" Shaft
Rated Torque 1128 oz-in,
- 8 N-m
- with Encoder 1000 line
Now what I found is, there is a dimensional discrepancy. I contacted the supplier and they sent me a link that they said should help, but it reflected the same.
The question that I have is a dimension on the frame size shown below.
This is (NEMA 34) KL34-8N-1000 That actually says 60mm (in red). The link to it is above.
All other dimensions are the same for NEMA 34, is there something I'm missing here. I contacted the supplier, he responded this morning, and gave me another link that should help, but its the same. And I thought I'd poised this here, is there something, I'm missing, frame size or something. I thought NEMA 34 should have the same mounting configuration.

And this is what I thought was a standard for NEMA 34. I circled in red the discrepancy
