I have a DC motor that has the attached wiring diagram, the question is, how should I wire this motor?, preferably to a PWM controlled motor controller
The datasheet attached is contradictory as it shows two wires on the figure and three terminals U,V,W on the table.
If it has three wires that is not a brushed DC motor but a brushless DC motor; which is a three phase AC machine. You need a three phase power converter or an ESC to connect to phases denoted as U,V,W. Hall effect sensors will allow for closed-loop speed control in case you are building/using a sinusoidal power converter which does not use six step commutation.
This might help:

Check the actual wiring coming out of your machine.

Thesis Design and Implementation of an Electronic Speed Controller ...
@Kris Scicluna it has 8 wires cumming out of it exactlly as described in the diagram, I have got the data sheet from the supplier. I was thinking that I would be able to build a controller for this motor(depending on the effort needed to build it) or just buy one, since my project is not really about motor controllers. what would you recomand ?
Thank you!

Therefore:
U,V,W - Power Terminals Phase A, B,C
5V, GND - Hall Effect Sensor Powers
HALL A, B C - Hall Effect Sensor Terminals with respect to GND
The dissertation I attached has full details on the construction of the DC-AC inverter for such applications but building, testing and control requires significant work. I would recommend an off the shelf unit. This should do the trick:

@Kris Scicluna for a motor controller that will be embedded in a product that will be produced serially what would you suggest?
