Motor

Both motors (drive, osc) were identical

PITTMAN
GM8712-41
19.1 VDC
187:1 RATIO
MFG 05-29-98 S

33 and 17 ohm. Is one of these damaged? Why are their resistances so different?

Tried testing under load

  • black goop
    • 12.19 V @ 1.266 A (current limited)
    • 8 ohm after
  • other
    • Initially drawing way less current than first
      • 12.12 V @ 0.332 A (voltage limited)
    • then started smoking
      • 11.68 V @ 1.248 A (current limited)
    • 6 ohm after

Aren't these rated 19.1 V? Am I misunderstanding?


Try pinning out the spare bad head

  • 1-5: 2.8 k
  • 2-6: 147 R
  • weird...


what does the secondary machine test? (believe good)

  • 1-5: 9.0 R
  • 2-6: 10.4 R


What is max voltage allied puts out on motors?

  • 1-5
    • 7.6 (fixed)
    • osc
  • 2-6
    • 15.0 (max)
    • drive


Head connector

Head plug

  • 4x2 (8 pins)
  • 3 mm pitch
  • Head female, cable male
  • Maybe Minitek Pwr™ 3.0 Series
    • https://www.digikey.com/product-detail/en/amphenol-icc-fci/10132445-08LF/609-5283-ND/7590945

  • 1: drive motor +
  • 3: drive motor -
  • 7 V

McMaster

2020-01-14

  • Win cross sectioning kit


2020-02-20

  • Order sample holder
  • Order replacement tubing
    • Later found I had some spare, but meh can use for other projects


Primary

2019-12-19

  • Submitted offer. Negotiations failed

2020-02-23

  • Observe osc motor is not moving
  • Observe osc doesn't have slit like spare to keep in place...how is it supposed to work?
    • Is this a DRM thing of sort where they didn't supply the right adapter if the user didn't purchase osc option?
    • ie the motor was intentionally disabled and also mechanically hindered
