Stray losses in a DC machine are not directly accounted for by the standard categories of losses (like copper, iron, or mechanical losses). Instead, they typically include additional losses such as those due to eddy currents and hysteresis in the machine parts not accounted for elsewhere, as well as friction and windage. Thus, the closest category that encompasses a broad range of unaccounted losses would be iron loss (which includes eddy current and hysteresis losses) and mechanical loss (which includes friction and windage losses).
