Hi i have a 24V BLDC motor. I want to rotate the motor certain angle or laps. The motor have 3 pin that "+", "-" and "GND". I'm not sure what kind of ESC i need use for position control. I found some ESCs but these ESCs have different pin names that "U", "V", "W". What kind of ESC do i need use to control for this motor?

What's the brand and model number? Got a picture so someone can identify it.
There is no brand of motor. i asked the supplier and they give info about pin names and SP2110/S3 female connector on the motor. all info are this. i just learn probably there is a controller inside of the motor but i don't know how to control this motor with these pins

Probably, what You need is a Stepper-Motor,
this will give You fairly precise positioning, and much better motion-control.

You need to give a detailed explanation of what You are
trying to achieve, or the problem You are trying to solve.

Sounds like a brushed DC motor.

More info on the motor is needed !!??

This is the document i have and supplier said that it is BLDC but i'm not sure the type.

I would say it has an internal controller so it is not readily controllable. This is similar to most PC fans that are BLDCs but not the sort you can control the position of.
This motor is not suitable for your project it appears. It REALLY would help if you can give some details of what you want to do. Like, what is the load the motor needs to move for example.
As @LowQCab states, you may do better with a stepper motor.

is the winding on the bit that goes round or the bit that stays still?

I attached the document about motor. At the beginning i just need to know how to control this motor. Now i'm not sure this motor is BLDC

It is not easily suitable for your needs.
You may be able to dissemble it, remove the internal electronics and add a suitable controller (if it is a BLDC).
Otherwise, you will need a micro controller, power H-bridge driver, and a rotary encoder for a start. Then the programming code to go with it all.
WHAT IS YOUR APPLICATION?
Why is it so hard to get real details???
Knowing what you really want to do makes it a lot easier for us to help you!

Is this it, for a solar tracker?

Yes it's for solar tracker but it's not important i think so i didn't give detail. First i need to learn how to control this motor but i can't specify type of motor i confused.

Probably easier, cheaper and more reliable to buy extra solar panels and keep them stationary.
I would suspect that you have a brushed DC motor. Take the cover off and see where the windings are, and whether you can see the brush gear. If so, it is likely to have 500 hours’ life.

What electronic experience and programming do you have?
Have you used Arduinos for instance?

But I agree with @Ian0 in that it would be cheaper to just add extra panels.

I have some experience about electronic and programming but i have no experience about this motor. Do i need just give 24V or need need controller?

If you can get away with fixed speed, a couple of relays can be used, for example, driven from an Arduino.
From this web site... http://www.bpesolutions.com/gadgets.ws/gtechgen.html

or you can use an H bridge driver and that will allow direction and speed control.
https://www.allaboutcircuits.com/projects/control-a-motor-with-an-arduino/ has some example code. But the L298 is not big enough to use and they are old and lossy.
Look for a 36V and 10A version at least.
An encoder driven from the motor can help with position sensing, and if it is not an absolute encoder, a home switch to calibrate it.
But, an AS5600 magnetic encoder on the output can "remember" the position.

These can be connected to an Arduino for control.
