This means you only have 1/256 of the inductance you had earlier. This makes the time constant of the motor insanely small, making the motor uncontrollable since the current rise is too fast for the controller - unless it's built for it.
Ok now I understand you, but you misunderstood me, the stator when I bought it was a generator for 250cc scooters not destined to be used as a motor.
That's why it had 41 turns, check the D.C. photo it says 19.9 Amps in WYE. That was the max amp I would get when used as a generator.
So when I was powering it up as a motor it wasn't running more than 20rpm and for 10seconds.Too many turns=low kv/rpm. That's why I rewound it,to make it a real motor for my application.
I used thicker wire to make it easier on the current draw but I couldn't wind it more with only my bare hands...So I thought it's ok, less turns=more kv/rpm right?
You are right about the current draw ,since it's in DELTA it is supposed to draw more current and have less torque.
Maybe I'll connect it in WYE and see what I'll get...Less rpm,less current draw and more torque.Thing is I was aiming for a motor of around 10,000 rpm and with WYE I'll get less rpm (or so I think...).
