    DC servo WEG typ: UE 301 TH/568, 80V, 1.3A

    Hi , i have purcased on a flee market for extra low price thre DC motors. WEG typ: UE 301 TH/568, 3-phaze BLDC motors, optical encouder with line driver RS422, 3 chanel optical comutation sensor. http://www.elektromehanika.com/servo/WEG/preview.html
    I complete mechanikal work on my CNC 60x40cm.

    questions:
    1. Where i may find driver for this thre phase DC motor? (circuit)
    2. how do i connect this motor? it have many wires , not only + and -.

    I am new in CNC and have much love for it.
    thanx

    Have a look at the VSD-E from Granite Devices, it can drive BLDC motors. I don't know of any DIY drive schematics etc for brushless motors. As for connecting it to the drive, the motor should have three wires and the encoder at least 6 wires for A+, A-, B+, B-, 5V, GND. You need to find a datasheet on the particullar encoder to find out what's what. Or you could trace out the circuit and figure it out but that's not easy of you're not used to that kind of thing.

    Thenx dude for answer. I have this in mind.

    Do enibody ever work wiht tis DC motor on any case?
    If exist driver for this motor i want to purcase it.
    I want to her expirience of oter mans that build CNC with thre phase BLDC motors. How other drive its DC motors.
    Salutation
