I still have a Maytech 6374 Motor (170 KV) so I would just have to buy another one to complete the set.
But I think 170KV might be too high for my 12S Setup.
I was also looking at APS Motors - those are not enclosed for the most part so the sensor PCB might be problematic for muddy/rainy terrain.
Most other suppliers that I checked are out of stock on certain motors.
Whats your thoughts ?
I think the motors should have around 130KV (or would you use 170KV and just compensate with gearing) ?
Would you use APS Motors - or can you recommend others that are on stock in Europe ?
Some People say they prefer sensorless because they are less likely to fail (I want to use them with a FOCBOX) - what’s your experience ?
Maybe I am also lucky and some motors pop up in the used items market.
Thanks again guys
have a great day
The Maytech 6374 work perfectly for a MTB, you just have to gear accordingly.
I had tried them with 13/66 gearing and they were fine. I might have wanted a little shorter gearing but I would be happy with that too. Keep in mind that I like very short gearing on an MTB since I live in a very steep area that gets really hot during the summer.
APS motors have a lot of problems. Do a search and you will find plenty. Stick with Maytech or Hobbyking SK8.
Sensorless does not work for MTB since you can’t push start. An exception to that would be the use of an external encoder such as AS5047.
I am not sure that the 190kv is accurate though, they are closer to 170kv.
I can’t measure the kv with the vesc terminal KV command since I run FOC, but I can tell you what erpm they reach at what V and you or someone else can figure it out.
The Unity has been rated for higher discharge, for longer amounts of time when compared to the single focbox, but the temperature aspect sort of becomes irrelevant when you strap a heatsink to it.
Ive heard of people doing 80a batt max on a single focbox(I think this was Kug3lis ?) But I would stick around 40a unless you have some good cooling
So I should wait until the unity is available in Europe ?
Then I will only order the motors and the direct drive and hope for the focbox unity to be available to EUROPEAN Suppliers as well
Unity batch 2 is shipping now, i would expect the likes of bioboards.se will have stock fairly soon at a slightly inflated price compared to enertion direct, but of course without the wait for batch 3.
