Hi to everyone!
I´m new here, and I´m a dentist.
I´ve been into electronics for a long time, as a hobby always, so I´m not a tech, but I enjoy building stuff.
Here´s my problem. I have one BLDC 3-phase motor, but I don´t have it´s control box. I´ve searched ebay, and found some PCBs which are general BLDC controllers, and allow a wide range of volts (12-36), allow me to control it´s speed and direction, etc. So, I guess I could build a control box for this motor I have.
There are no specs for it, and I can´t get it. It´s a replacement motor for a dental device, and there´s no info on what´s inside.
I do have another one which is exactly the same, with it´s original control box (the one I use everyday)
So, how can I find out on how many volts is this motor supposed to be driven, it´s current, etc? I know it´s not simple as attaching a multimeter in parallel and in series, because brushless are different..
Is there a way for me to find out?
I´ve have a 2 channel oscilloscope soon. I´ve ordered it over ebay, but it may take weeks to arrive to me...
I have this other complete unit, working, with it´s original control box (sealed, never opened it). Sois there a way for me to "check" the volts, amps from the original controller to find out how much power I need to drive the motor?
I know it´s easier to buy another original control-box, but i don´t want to spend more than 1000 dollars on it right now...
I´m sorry if I didn´t make myself clear. English is not my first language..
Thanks a lot!
