BMC / MAC 500w-1000w hub motor stator dimensions?

[neptronix]

Hey folks...

I'm wondering if any of you know the following dimensions for the stator on the 500-1000w BMC and MAC motors:

1) Total circumference of the stator.
2) Stator width w/o copper.
3) Stator width w/ copper width included.

May not be what your looking for , but the only measurements I could find.

I have been pushing 2-4k into a mac 8t for a while now.. bought 2 so i can part it out as stuff breaks.

Looking forward to seeing how your new motors do.

Thanks for trying, but that doesn't help ohzee .. the stator diameter and width are far smaller than the hub motor's dimensions in these geared motors. I've pulled a few mostly apart, just never went through the stator removal process.

Hoping someone here can chip in.

Also, stator dimensions of the 'can' scooter motors ( IE the 600w, 1000w, 1500w, 2000w MAC/BMC motors ) would be useful too.

The 2000w MAC so far is 135mm in circumference, 22mm stator, and including copper width, the stator is approx. 28mm wide.

I see now - sorry I actually have the 2nd motor apart. I have been painting the windings with insulating varnish.

135.06mm circumference
27.08mm measuring copper to copper
21.96mm w/o copper

This is an 8t from cell_man. I have an 8t from lyen which seems identical as I have swapped parts with no issues.

I even have an extra stator on top of those 2 mac's - I really plan on seeing what I can do with these.

It's in a urbancommuter mid kit so a little different then pushing it in a wheel.

Well, there goes my day. I have more copper width than you, by 1mm. The stator of this motor is identical. I don't see how this is a 2000w rated motor.

I will weigh the motor now to see if i got the right one :/
