I don't see any customary star straps across the terminals?
Max.

Because all this "straps" are outside the motor in control box. And I suspect the Dahlander (two speed-motor) connection.
But of course I could be wrong.

That is exactly what I said in my previous post, star-delta starter!
Max.

 

So, start-delta started motor in a system designed for 380V.
But OP wants to run it on 220V only. Should be possible if OP is willing to modify the control circuit to disconnect from the star-delta starter and wire it permanently as Hohe Drehzahl.

 

This is not star/delta but as we can see the motor is connect in star but the motor has two speeds.

OK and what's mean that?

As you may have gathered this may not be a simple hookup or transfer over, this is why the external wiring/connections were asked for.
I suspect you may be a little out of your depth here?

I only see a 1700rpm (4 pole) motor, star delta does not change the rpm.
Max.

 

can you show pics of the ends of the cables from the motor, to see how its working.

But, but, but... see pic in post #15 niedrige drehzahl hohe drehzahl

 

I think its nit star delta. Its high spd low spd, hence no 220v rating on the nameplate

 

According to the label inside the peckerhead, the two options are 1.) Delta, and 2.) Star with half as many poles. See translation attached

.OK. what the best solution to be conectit at 220 v.

I missed Pole count change, I stand corrected.

I can't tell you it's a good idea to run it on 220v. If it were my motor i would connect it in delta and try it. But i wouldn't try it if it wasn't my motor or if i couldn't afford a failure.

OK. If I want to replace the motor with one on single phase,which motor I should buy to be the same power.

One with the same hp/kw rating and speed rating as what you have:

Hi.the motor it's a 4.5 kw and 6.2 HP,and I want to know if it's eny way to be conectit at 220 v. Thanks.

BTW were talking this whole time about how to connect your motor to run on 220v single phase?
Because if so, that is not, and was never possible.

Also, be aware that a single phase motor of the same rating will draw a lot more amps than the 3 phase motor that you have. You will need to verify the size of wires, fuses, breakers, contactors, and overloads in the system to verify everything can handle the increased current before purchasing a motor.

Hi.do you think a static convertor will be helpful for me or I need a rotary converter?

 

The higher current will also apply to a 220v 3ph motor.
Re-reading the plate I see the two rpm's are 700/1390.
If you use a RPC or static conv you will still need a higher voltage for that motor.
If you want variable rpm for a single speed motor it might be wiser to look for a VFD and use 220v 1ph input and a standard 3ph 240v 4 pole motor.
You can also set them for a series of fixed speeds.

Hi.i find this motor.you fo yoi think that will be OK.

Hi.i mean to keep the three phase motor and to buy a convertor,but I don't know wich one its better,static or rotary converter.

 

Static would be the better choice or VFD, IMO.
