This is what freaks me out a little about BMS battery.
You can get both the 36v and 48v versions in 393rpm.
Now given the rated volts @ 36v and 48v this would mean that the 36v version should be a different wind to the the 48v to enable the same rpm.
Can anyone claify this?
Yeah, it's confusing as hell.
I've been trying to get my head around this for a while now and I think your observation that,
Quote-"Now given the rated volts @ 36v and 48v this would mean that the 36v version should be a different wind to the the 48v to enable the same rpm."
Is the key to understanding what BPM winds BMS Battery actually offers, at least the higher rpm winds.
Here is what I think I know,
Based on what Rizo said,
Quote "...bmsbattery answer me this:
48V 500w rpm393, Front. code 11.
48V 500w rpm393, rear, code 10 ...."
Bms Battery only offers three BPM high-speed winds, there are,
The 48V, rear mount w/ a no-load rpm listed as 393, is a Code 10[310 rpm @ 36v].
The 48v Frt. mount w/ a no-load rpm listed as 393, is a Code 11[285 rpm @ 36V].
And according to jateureka,
Quote-"I ordered the 36V 350W front BPM motor in a 201 rpm winding from BMS Battery and received a 26 (13) motor."
So is't possible that,
The 36V frt. or rear mount w/ a no-load rpm listed as 393, is a Code 13[225{my est.}rpm @ 36V].
Has anyone recieved a 36V[393 rpm]rear and can confirm that it is a Code 13? The Ebike CA sim. indicates that it is closer to a Code 11 or Code 12.
These codes seem to jive with the top speeds for BPM faster winds that I have noted here in ES.
Concerning the slower winds, I'm still rather perplexed. Both Gartmu and d8veh have indicated that the 201 rpm winds produce Euro-legal speeds of 20 KpH @ 36V, so I will assume that,
Both the frt. and rear 48V slow-winds motors are Code 8's[201 rpm @ 36V].
But where does that leave the 36V slow winds? Could they be the same as the 48's[V]?
Code 8's?
Anyone want to comment on this remarkably obtuse system[perhaps a plot to make us mind-dead?]. I hope I haven't muddied the waters even more.
