DC Generator Plot explanation

Summary:: Hello

Got the following plot (please see below), and am trying to figure out the phenomena behind it (plot behaviour)

What do you guys think?

It's a DC Generator to be calibrated. On the x axis: the ratio between the power of the generator / nominal power of the generator, while on the y axis: the generator efficiency.

In terms of an explanation for the plot behaviour, thinking that the efficiency of the dc generator peaks at low ratio between the powers, declines at higher ratios of powers.
