6. No-load loss
The no-load loss rates of Miter Gear Boxes are shown in the table below.
This data is calculated from actual measurements at room temperature (25°C) and should only be used as a reference as it can be affected by the ambient environment and operating conditions. These values are not guaranteed.

Calculation of no-load loss
・When running ED6M1-LR-Y (reduction ratio: 1:1) at 2000 rpm:
Based on an input kW of 18.6 kW and a no-load loss of 10%, no-load loss is calculated as 18.6 × 0.1 = 1.86 kW.
