@Anubis, can u check this thread I’ve posted some time ago ? https://forum.esk8.news/t/strange-noises-from-the-motors-any-idea/25525 , are you referring to this phenomenon ? If yes, will other motors than maytechs will not suffer from this problem ? (I’m looking for a better solution)
I’m not crazy about the sensor wires running the length of the stator… but it is what it is…
when you ran the flipsky’s did you have the Temperature sensor on, or just totally sensorless?
great to hear HFI works well… I can’t wait to get my grubby little paws on mine…
thanks for the GB, Ben!

I just ran sensorless, i am too lazy to open my enclosure and connect sensors. Usually i just run a stress test, see how hot it gets then adjust the current values until its all about right.

Ill subscribe to your only fans if you try one.
@itsrow The problem is the 6374 size is weird for me. It’s too big for a dual drive and too small for a single drive imho.

Ah yea I didn’t see that ring. Well-designed.

What amps? Any modifications? Epoxy? Or do you just run them as is
They run cool below 60 amps, I run mine at 50. You can epoxy them, but they’re still not greatly reliable in other ways

Motor amperes or battery amperes?
I assume the latter?
Motor amps. They don’t have temp sensors so in general the settings have to be quite conservative

Great comparison.
Could you speak to the bearings and motor shaft retention for each? Motor shaft to can retention has plagued many of these motors.

They are using two grubscrews that locks into matching holes that are maybe 1-2mm deep in the shaft, so there is som mechanical look there not just a flat spot. So can to shaft slippage should not be a problem most likely. They are using NMB bearings. A very large bearing manufacturer one in the back two in front.
They use a spring steel washers between the motor can and the c clip to put a preload on the motor housing to get rid of stupid vibrations between the motor can and stator.
I have done about 400-500km on mine already in all types of weather conditions. The curved magnets makes them run very quiet in foc and with higher switching frequency they are stupid quiet.
Actually my favourite motors so far.
Keep in mind I’m biased as I have been fairly involved in designing these motors.

Just passed 100km on mine. Had some really nice weather, they’ve been great. Flipsky’s recent product releases really have been good
