Brushless DC Motor has two constructure , Synchrunous machine and DC machine , which one is suitable for modeling . Photo of my Motor you can find in attachment.

Also i find that the Sator is solidary and there is just 2 Point for Terminal voltage, but in datasheet of my Motor stands 2 Phase brushless DC Motor.I have a Controller before he Motor which is integrated in Motor  and Output of Controller has 5 terminal and are distirbuted and ae soldered in Stator. Rotor is Permanent magnet and cylindrical. Totaly i have a Permanent Magnet Brushless DC Motor. whic Kind of machine we have and how can i measure the Parametres of related machine?
