Dynamometer
The Micro Dyne offers two different torque configurations in one unit. Depending on the motor’s maximum torque rating, the user can easily switch between the 2.0 mN·m and 4.0 mN·m torque settings via the dynamometer’s rear access panel. The ratings are the same for either configuration. |

Power Absorption Curve
Based on the maximum kinetic power ratings, the curve below represents the maximum power (heat) that the dynamometer can dissipate over time. The area under the curve equals the maximum torque/speed combinations for both a motor test of less than 5 minutes (intermittent duty) and a continuous-duty motor test. |
