Allright, finally got some pics. Had to work all day and had the motor box sitting in front of me all day! time to check out the new toy!
Two big MACs. One to blow up finding it's limits, one to ride with on a permanent basis
First note is the huge black plastic case and 12 gauge phase coming out of it.
The axle is flipping huge.
22.3mm.. that's a 7/8" shaft size in inches, which seems to be fairly standard.
70mm width, so ~2.7 inches. This would fit inside a bike triangle pretty well.
I'm missing my tape measure and my caliper is maxed out. I'm gonna guess this is 165mm in width ( 6.5 inches ). The plate adds quite a bit of extra width too, maybe the total diameter is 180mm or so ( 7 inches ). I'll get more exact dimensions later.
Ghetto rigged boat chair seat swivel from wal-mart fits over it..
And fits under it.. i could sandwich the motor between these if i wished. Cool!
mock bike mount..
mock bike mount showing chain line..
Okay, opened up now and oh no, shrinkage! apparently the case is very oversized. Oh well, i was warned.
Cooling holes pre-drilled, sorta like the BMC motors..
Magnet diameter, about 23.5mm or so ( hard to measure here )
Total stator circumference is 135mm.
22mm stator width.
Or 28mm with copper..
Hall sensors and what looks like maybe.. a thermistor?
Okay, back to the case... looks like there is a groove that you could use to seal the motor up by inserting an o-ring, or throwing in some RTV gasket maker, to waterproof the motor.
And last but not least.. showing how oversized the motor cover is.
Overall first impression... this is most definitely a lawn mower motor. It's very overbuilt. If redesigned, it could easily shed pound or two for eBike usage. The case size could be drastically reduced as well. I think the 7/8" shaft is going to have to be cut down for eBike usage, and maybe a custom case could be made as well.
Should have some actual motor tests in a few weeks. Life's a bit hectic but you will definitely hear more about these later
