Web4 Jul 2024 · Rotational losses are mechanical in nature and are thus subtracted from the mechanical power. That's why the core and stray losses are shown before the conversion from the mechanical domain to the electrical domain. So, stray losses and core losses are not mechanical power losses, but they are subtracted from the mechanical input power … Web31 Jan 2024 · Friction loss at commutator and bearings, which are about 10 % to 20 % of full load losses. Why do I have stray losses in my DC generator? They are usually due to inaccuracies in the designing and modeling of the machine. Most of the times, stray losses are assumed to be 1% of the full load. The most convenient method to understand these …
