Friction in the bearings and in the commutator, and windage loss. Electrical resistance of the armature and field windings and the brushes.
What are the functions of Total productive maintenance?
to meet the client satisfactions and to insure that all equipment are in good running condition, to prevent loss of quantity of production,, and to have more accurate reports on when or when this equipment will get damage or to give information on the status of the machine,, for future reference,,and carry all standard procedures for the maintenance of equipment
Why are distribution transformers frequently designed to develop maximum efficiency at loads that are somewhat lower than rated value?
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
Why shunt field resistance is high incase of dc shunt motor?
Back emf is proportional to the flux in the field winding.Flux in the field winding is proportional to the mmf in the winding.mmf = current passing through the winding * no of turns in the windingTo attain the required mmf we can use more current and less turns ( or ) less current and more turns .As the power loss in the field winding is considered it isPower loss = Square of voltage / resistanceAs the voltage is constant for a high resistance it is possible to have less losses. So we prefer for high shunt field resistance.As the field resistance is high current is less , so no of turns in the shunt field will be more to attain the required mmf.Answer'Shunt' is an archaic term for 'parallel', so the shunt winding is in parallel with the supply voltage which means its resistance must be relatively high to limit the current passing through it.Incidentally, the back-emf. is not proportional to the flux, but to the rate of change of flux.
Why you are generating ac not dc?
question is wrong....ac is generated in alternator <<>> The most likely reason is that there is no field voltage being generated. This is controlled by the voltage regulator. Check to see if you are getting a DC field voltage. On the voltage regulator there are terminals to different pieces of equipment on the machine. Look for the terminals that are designated F1 and F2. These should have a DC voltage on them. Also look for a potentiometer that controls the field voltage. Turn it one way and the voltage will go down and turned the other way the voltage will go up. Make sure that this potentiometer is in the correct position to allow voltage to the field coils.
