- The losses associated with mechanical friction of the machine are called mechanical losses
- These are primary function of speed
- These losses occur due to friction in the moving parts of the machines like bearing, brushes etc. and windage losses
- Windage losses occur due to the air inside the rotating coil of the machine
- These losses are usually very small about 15% of full load loss
