Ha ha. i can see it actuallyTemperature sensor is installed between the windings directly in front of the hole, poured lacquer. You can't see it - it is covered with copper.
hows the rotor stability with the inner (wire side) cover removed? would it be at all possible to run it without the inner side cover, leaving one side open?VasiliSk wrote:I've run some tests on rv160s motor. On this graph horisontal - rpm, vertical - power consumption...
as you can see when motor runs 4k+ RPM, power rises above 1kW!! I have find out that main problem of such losses is a big bearing, it is heats up instantly when motor spinning 4k.
Here is explanation vid: https://youtu.be/qTRJ4jqASRA it is in russian, but easy to understand where is problems
So i replaced this original NSK 6814 bearing to NTN 6814, cover now spins much longer!!
And finally some photo of RV160s
magnet width 25mm... winding NOT 6 parallel wire, but 5. im quite dissapointed with this motor
thx for that data and this graph about no load consumption. now we can add it to the comparison thread: https://endless-sphere.com/forums/viewt ... 0#p1168909VasiliSk wrote:Got this data from RV160 short
this gives me 39.6Nm on shaft of motor with 180 phase amps
I am very intrested in seeing the rewind and the differences it will give.VasiliSk wrote:After rewinding, Km should rise a lot
Optimal rpm? How can that be determined, and of what use is it unless you have long distance constant speed cruising.VasiliSk wrote:Yes, but after some tests. i need to find out optimal RPM
