NuiCent 31YZ — Pick Your Speed & Gyro Size
NuiCent 31YZ — Pick Your Speed & Gyro Size is a standalone digital development package by Will Cole. Choose one configuration for £19.99. No previous NuiCent purchase is required.
120 mm Mini carrier family
The current Mini source uses 120 mm 31YZ carrier plates. Six speed labels are supplied as development targets:
| Option | Gyro / carrier target | 31YZ shaft target | T41 upper input | T36 study input |
|---|---|---|---|---|
| L4 | 1,000 rpm | 4,000 rpm | 390 rpm | 444 rpm |
| L8 | 1,000 rpm | 8,000 rpm | 390 rpm | 444 rpm |
| M4 | 2,000 rpm | 4,000 rpm | 780 rpm | 889 rpm |
| M8 | 2,000 rpm | 8,000 rpm | 780 rpm | 889 rpm |
| H4 | 3,000 rpm | 4,000 rpm | 1,171 rpm | 1,333 rpm |
| H8 | 3,000 rpm | 8,000 rpm | 1,171 rpm | 1,333 rpm |
125 mm 4×31YZ gyro family
The separate 125 mm development module uses a calculated local ratio of approximately 2.6163:1 in its documented T36/T45-to-31YZ study. Useful reference points are:
| 125 mm option | Local input reference | 31YZ shaft target |
|---|---|---|
| 125-35 | about 1,338 rpm | about 3,500 rpm |
| 125-40 | about 1,530 rpm | about 4,000 rpm |
The 125 mm carrier's own orbital RPM is a separate quantity and is not assumed to equal the 31YZ shaft speed.
What the selected package is for
- Matching CAD/reference material for the selected development configuration.
- 31YZ speed and pulley calculations.
- Relevant STEP/STL or source-CAD files where supplied for that size family.
- Belt-route, pulley-fit and build-reference material.
Development status: these are calculated prototype targets and reference configurations, not certified motor ratings or guaranteed measured operating speeds. Physical builds should verify carrier RPM and 31YZ shaft RPM with a tachometer under the intended load.
Digital files only. Motors, bearings, belts, fasteners and electronics are not included.
