MECHANICAL LOSS These losses consist of friction and windage losses.
{"Image DocumentName": "MECHANICAL LOSS These losses consist of friction and windage losses.", "Image ImageDescription": "Some power is required to overcome mechanical friction and wind resistance at the shaft. This loss is nothing but the friction and windage loss. The mechanical losses are also constant for a d.c. The magnetic and mechanical losses together are called stray losses. For the shunt and compound d.c. machines where field current is constant, field copper losses are also constant. Thus stray losses along with constant field copper losses are called constant losses. While the armature current is dependent on the load and thus armature copper losses are called variable losses. Thus for d.c. machine, Total losses = Constant losses + Variable losses.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
