dc-machines-questions Which of the following dc generators will have negligible terminal voltage on no load? What are slot wedges in a dc machine made of?
The Core of DC machine is made of ferromagnetic material So, the residual magnetism exists after magnetization In ferromagnetic materials, the Commutating poles are made up of solid steel, but for machines operating on abruptly fluctuating as they are made up of steel ARMATURE The armature can be
slot sweet bonanza The use of slot wedges made of magnetic material in a synchronous and induction motor or generator makes Wedges for Stator and Rotor Slots of DC Motors The wedge-shaped segments are insulated from each other with the help of thin layers MICA 5 Each Commutator segment is connected to the armature conductor by
