Any ideas how to control the middle motor with arduino ??
It doesn't work like an ordinary motor (because is big )
and I don't have any idea how to control it please help!

A photo isn't much help - all motors look the same.
What sort of motor is it? a regular brished DC motor, or a brushless DC motor, or a stepper motor, or something else?
Can you post a link to the datasheet for the motor?
...R
I can’t find the datasheet ( and the buyer ).
The only thing that I know is the label over the motor:
MODEL: GM05009009
PMI Motors
KOLLMORGEN CORP.
SYOSSET, N.Y.
I think is a Kollmorgen PMI Motion ServoDisc DC Motor...

Help me out a bit here ??
What do you infer from that description?
How did you get the motor?
What do you want to use it for?
How many wires come out of it?
Have you made any attempt to get it to rotate?
If so, what did you try and what happened?
And anything else you can think of ....
...R
What do you infer from that description?
Maybe nothing but It's a start.
How did you get the motor?
The motor It was inside on a machine.
The purpose of the motor is to move up / down one platform with the anointing of a belt that is connected to one side of the motor.
What do you want to use it for?
I want it for the same purpose but to control it from arduino.
How many wires come out of it?
Two.
Have you made any attempt to get it to rotate?
Yes ! but only on the machine , It operates at 14V ans 47mA supply but I can't rotate It with arduino.
If so, what did you try and what happened?
When I tried to control it from arduino,It started to produce a loud squeaking sound without spinning.
and I used this driver:
It operates at 14V ans 47mA supply
Think about that - 47mA for an industrial servo motor.... I don't think so.
Measure the armature resistance - I would expect it to be very low in
this type of motor.
Do you mean by
at 14V ans 47mA supply
that you have a 14v power supply that can only supply 47mA when connected to the motor?
Or do you mean that you have a 14v supply than can provide several amps but the motor only takes 47mA?
Do you know anything about the machine the motor came from
- for example is there any reason to suspect it was designed for a high voltage supply?
- was it required to do heavy work in the machine?
As @MarkT has said, measure the resistance.
Post a diagram of how you have the Arduino, the driver and the motor connected.

send KOLLMORGEN CORP an email and ask

I wonder are they prepared to spend more on the reply than the OP spent on the motor?

Kollmorgen doesn't have the time to help every hobbyist with an old motor. What you CAN get from their site is an idea of how big and how much power a motor that size will take. Without the rest of the circuit, we are hard pressed to decipher why it would squeal when you connected it. I suspect something was current-limiting at that frequency. From their catalog, you can see they make many "servodisk" motors that run off 24V and several amps. From the picture it seems it's a DC motor (only 2 wires). See if you can get it to spin by putting it on a car battery. It should rotate at HALF its design speed, and we know the car battery can supply 10 amps or better. I suspect it will run about 24V and 7A, so right away that little L298 Controller won't push it. You're going to have to "up" your game.
A car battery in good condition can supply >600A, so you always put a fuse in the
circuit, avoid wearing metal watchstraps/jewelry... Should definitely shift that
ironless servo 
I would wear leather gloves when trying it across the battery. If the motor is seized or shorted those wires are going to glow red. If it's a 24V or better motor and you connect it to 12V it should at least turn. If you feel brave, put your Multimeter in CURRENT mode and see if you can read the current. If it's 3.5A at 12V, it should be about double that at 24V.
Then if all the above looks reasonable, this would be a good job for that little 43A H-Bridge they sell on e-bay. You will need to use one between your motor and Arduino!
