CPM-80-25 Measured Performance Data¶
Status: Public engineering reference
Source: SigGear CPM-80-25 catalogue dynamometer data
The data below contains representative measured points from CPM-80-25 dynamometer testing at 24 V, 36 V and 48 V. These are test observations, not guaranteed continuous operating points.
Actual results depend on controller settings, current limit, thermal state, duty cycle, assembly configuration and test setup.

| Test | Ambient temperature |
|---|---|
| 24 V data set | 28.4 C |
| 36 V data set | 28.8 C |
| 48 V data set | 28.5 C |

Interpretation¶
Do not use stall points as continuous operating ratings. The public rated output torque remains 10 Nm and peak output torque remains 50 Nm for preliminary product selection. Confirm the required torque-speed cycle and peak duration for the actual project.
