spleblem Posted May 28, 2007 Report Share Posted May 28, 2007 hey guys im doing a school physics project on how a microwave oevn worksand im going to go in to a fair bit of detail of all the electronic components like the high voltage transitor and the special light needed and all about the magnetors.so i was after a service manula on any moden microwave ovenand i was also hopeing to find a explosion diagram of a microwave ovenso any help at all about this assigmnent whould be greatif you got any links to sevrice manuals that would be great tothanks alot in advance Quote Link to comment Share on other sites More sharing options...
AN920 Posted May 28, 2007 Report Share Posted May 28, 2007 Here is a conventional diagramhttp://www.eserviceinfo.com/downloadsm/27009/Daewoo_KOR-180A2A,%20KOR-181G2A,%20KOR-181H2A.htmlAlso http://www.repairfaq.org/sam/micfaq.htmMany modern microwave ovens now use a HF, high voltage switch mode PSU Quote Link to comment Share on other sites More sharing options...
spleblem Posted June 3, 2007 Author Report Share Posted June 3, 2007 that the links are greatbut im having a bit of trouble understanding how the magnertron worksi know that current flows out the hot filament and the spirals around befor getting tothe anode becuase of the magnetic fieldbut im not sure about how the rest workshow the current goes into the cavitys and stuff ahppens in there which makes the microwaves.can someone explain in a grade 11-12 level for my assigment thanks in advancesteve Quote Link to comment Share on other sites More sharing options...

spleblem Posted June 3, 2007 Author Report Share Posted June 3, 2007 im still not really understanding what happens inside these cavity thingshow the electrons are changed into waves Quote Link to comment Share on other sites More sharing options...
Omni Posted June 4, 2007 Report Share Posted June 4, 2007 The cathode is generally pulsed with a negative potential using a HV DC source, within the core of a circular chamber the latter cathode is placed.Angular to the core a magnetic field is constructed which in turn allows the electrons to spiral out in a circular pattern to the anode.Provided around the outer edge of the core are additional cavities, as the electrons pass the latter opening they resonate at a high frequency.The circular pattern cause the electrons to push together (group).A small amount is forced/directed to a metal tube (WG), the waveguide emits the high Freq RF energy to the cooking containment area for heat etc...Actually, the above process is similar in relation to a klystron tube but much more efficient.Although, a klystron is better suited for other applications; High power transmitter etc...Final note: Use caution around any HF wave when experimenting since radiation is emitted in a dangerous manner when uncontrolled; dont take the path of Madame Curie...-Omni Quote Link to comment Share on other sites More sharing options...
spleblem Posted June 4, 2007 Author Report Share Posted June 4, 2007 so as the electron pass these cavity things inbetwen the anode it cause them to resonate and that force a small amount of force to the metal tube which cause electromagnetic wavesright?
