Electrical Machines In dc machines, the field system has to be provided on stator unlike synchronous machines Where in it could be on any member, because it reduces field structure iron losses dc machines are comparatively low rating machines. it gives more uniform air-gap flux distribution commutator action is not possible otherwise it reduces field structure iron losses dc machines are comparatively low rating machines. it gives more uniform air-gap flux distribution commutator action is not possible otherwise ANSWER DOWNLOAD EXAMIANS APP
Electrical Machines The magnetic circuit of a dc shunt generator with negligible armature resistance and brush contact voltage drop remains unsaturated when it delivers full-load current at rated terminal voltage. The brushes are kept in the interpolar axis and speed is maintained constant. When the load is switched off, the terminal voltage would decrease become zero increase remain the same decrease become zero increase remain the same ANSWER DOWNLOAD EXAMIANS APP
