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
- Initially drawing way less current than first
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
