larsb said:All that extra copper length and resistance.
It's got distributed winding, how can it be worth it? In theory there's less harmonics and eddy losses, higher winding factor but it must be possible to improve a lot with a concentrated winding..
MJSfoto1956 said:According to my QS salesman, the V4 motors are slower on takeoff but faster in top speed than the V3 motors (all other things being equal). Here is a chart I made from one of their few published comparisons of V3 vs. V4. Take it with a grain of salt please -- nothing scientific here at all.
larsb said:I don't understand. Why do you post this? Is there a dyno plot? If so, then please post the original. This chart smells like a chinese sellers sales talk and doesn't help anyone if it's not corresponding to a real motor.
What would be the problem that needs to be solved by soft startup? And how do you get a faster motor with same kV?
It's not correct.
flat tire said:It's true. That plot is worthless.
sn0wchyld said:dimensions and weight? cant find the V4 on their site...
MJSfoto1956 said:So you calling me a liar now?
larsb said:So the search doesn't actually show the correct motor?
larsb said:And how does the motor go 18% faster with same kV and all else the same?
larsb said:Why do you post it?
larsb said:I read mjsfoto drew the chart, it was done without any backing data. Fair enough but the format (to me) indicates some facts behind it.
