What outrunner would you use?larsb wrote: ↑Mar 07 2019 5:18pmthe revolt reviews are in my posts. Well documented, and i think you already wrote earlier that you read some of them.. In the rotor losses thread possibly.
The low copper fill, useless soldering of wires etc has been a general issue for Revolt. It was 22% copper fill in my motor originally..
And if the laminations are low quality like in Revolt case then it's not better with lower pole count.
Now I remember your posts on the Revolt motors...not very thorough or detailed. Obviously I'm going a lot further with lots more detail than you did. no offense intended there, but this thread is intended to expose everything about these motors...good and bad.
I do honest reviews...show the good and bad for the benefit of everyone. I've already said several things about the RV-100-reg and RV-120-reg that I don't like. I also point out things I LIKE about them. I'd do that for any review.
Lower pole count plays several roles. What about motor eRPM? In an outrunner especially...like the 120 and 150 series AP motors...all those poles makes running those motors on typical EV controllers impossible because the eRPM is so high. Keeping eRPM down will also help with iron losses. I'll be posting test results from running this motor at various voltages to see how the iron losses play out. There's lots to cover yet...
I'll get the motor apart further soon enough and then I can post images and measure the lam thicknesses. They are probably no worse that the AP 12090 that I am comparing it with.
What do you expect from a cheap motor? I never expect perfection and you do get what you pay for.
This is far better copper fill in the 120-reg. There's still room for a bit more copper here, but I'd call this 80% full.
Than this on the 12090...where the stator teeth are 60% full.
Same here...the RV-100-regular has an 80% full stator.
While the AP C80100 is more like 60% full.
