Hi guys,
Do any of you happen to know the wire color and correct voltage for the hall sensors on a API Gettys Turbo Servo Motor, model MEB-341 ? This is an 8 pole brushless motor with a Renco encoder, but the hall wires are separate from the encoder and come out from the inside of the motor. I am pretty sure this means they are true hall effect sensors and not just encoder tracks, so they might need +/-12V and be open collector transistors.
The 5 wires which I believe are the hall wires are yellow, brown, green, orange and blue. No obvious choice for which ones are power and ground.
The fatter, motor phase wires are black red and white, but I can figure those out with my oscope anyway.
I have scoured the internet and API's website and also Elwood-gettys website, but no luck. I can do a phone call, but would really like to get this spinning today, so I can test my Taig spindle drive (driving the spindle with this motor, hopefully).
Thanks for any help!
