η_{{MG}_{i}} = \frac{60 \times U_{i} \times I_{i}}{2π \times M_{i} \times n_{i}} \times 100

All efficiency measurements are to be performed consecutively at least five (5) times. The average of the measurements at each operating point ( $\bar{η_{{MG}_{i}}}$ ) shall be calculated.

The efficiency of the motor generator (η_MG) shall be calculated in accordance with the following Formula 2:
