Any body know , it's motor had how many pole?

thanks you very much

Hallo nhatson.
a think.. blue and white is phase 1
and green and red is phase 2..
give him 30-35 Volt AC..
his make work..
Encoder pin 25 und 26 has give you 5 Vpp of Oscilaskop..
a think so..
a have make a reparier with tornos maschin baujahr:2007

I would think it would be more like the three stator connections red,white,blue and green ground, a resistance check would confirms this.
This would apply for DCBL or AC sinusoidal.

I want control it with FOC, for that reason, i need check it had how many pole ?

any body help me

thanks alote

If the three stator windings checks out as I indicated, wire a 10k resistor to each connection and connect the opposite ends to a star point, this you use as a common for an oscilloscope check between this point and Red, if you rotate the shaft, every positive sine wave output per mechanical revolution x2 will give you the pole count.

Hallo nhatson..
you must open the motor and look to.. in motor..
and see this Stator or (Wicklungs-Anordnung)
sorry my english is not so good.

Good Look my Friend..

thanks elektriker
I was open it, but i can't see winding because it cover by epoxy

Thanks Al the man, it have 4pole.

thanks you again
