servo drive e sebetsa joang:
Hajoale, li-drive tsa servo tse tloaelehileng li sebelisa li-processor tsa matshwao a dijithale (DSP) e le setsi sa taolo, se ka hlokomelang li-algorithms tsa taolo tse batlang li le thata le ho hlokomela digitization, marang-rang le bohlale.Lisebelisoa tsa motlakase ka kakaretso li amohela potoloho ea koloi e etselitsoeng mochini o bohlale oa motlakase (IPM) joalo ka mantlha.Qala potoloho ho fokotsa tšusumetso ho mokhanni nakong ea ts'ebetso ea ho qala.
Setsi sa ho khanna motlakase se qala ka ho lokisa motlakase oa mekhahlelo e meraro kapa matla a mantlha ka potoloho ea mekhahlelo e meraro ea borokho bo felletseng ho fumana matla a DC a tšoanang.Kamora ho lokisoa ha motlakase oa mekhahlelo e meraro kapa motlakase oa mains, mochini oa motlakase oa mekhahlelo e meraro oa AC servo motor o tsamaisoa ke phetoho ea maqhubu a mofuta oa motlakase oa sinusoidal PWM oa mekhahlelo e meraro.Ts'ebetso eohle ea yuniti ea ho khanna matla e ka boleloa feela hore ke ts'ebetso ea AC-DC-AC.Potoloho e ka sehloohong ea yuniti ea tokiso (AC-DC) ke potoloho e sa laoleheng ea borokho ea mekhahlelo e meraro.
Ka ts'ebeliso e kholo ea lits'ebetso tsa servo, ts'ebeliso ea li-drive tsa servo, debugging ea servo drive, le tokiso ea servo drive ke litaba tsa bohlokoa tsa tekheniki bakeng sa li-drive tsa servo kajeno.Bafani ba litšebeletso tsa theknoloji ea taolo ea indasteri ba ntseng ba eketseha ba entse lipatlisiso tse tebileng tsa tekheniki mabapi le li-servo drives.
Li-drive tsa servo ke karolo ea bohlokoa ea taolo ea sejoale-joale ea motsamao 'me li sebelisoa haholo lisebelisoa tsa boiketsetso joalo ka liroboto tsa indasteri le litsi tsa mochini tsa CNC.Haholo-holo servo drive e sebelisoang ho laola AC e sa feleng makenete synchronous motor e fetohile sebaka sa lipatlisiso lapeng le kantle ho naha.Li-algorithms tsa hajoale, tsa lebelo, le maemo a 3 a koaletsoeng a li-loop tse ipapisitseng le taolo ea vector hangata li sebelisoa moralong oa li-drive tsa servo tsa AC.Hore na moralo oa lebelo o koetsoeng ka har'a algorithm ena o utloahala kapa ha o na karolo ea bohlokoa ts'ebetsong ea sistimi eohle ea taolo ea servo, haholo ts'ebetso ea taolo ea lebelo.
Litlhokahalo tsa sistimi ea servo drive:
1. Lebelo le pharaletseng la lebelo
2. Ho nepahala ha boemo bo phahameng
3. E lekaneng phetiso rigidity le phahameng lebelo botsitso.
4. E le ho netefatsa tlhahiso le boleng ba ts'ebetso,ntle le ho hloka ho nepahala ha boemo bo phahameng, litšoaneleho tse ntle tsa karabelo e potlakileng le tsona lia hlokahala, ke hore, karabelo ea matšoao a ho latela taelo e hlokahala hore e potlake, hobane sistimi ea CNC e hloka ho eketsa le ho tlosa ha ho qala le ho qhoma.Ho potlakisa ho hoholo ho lekana ho khutsufatsa nako ea phetoho ea sistimi ea phepelo le ho fokotsa phoso ea phetoho ea contour.
5. Lebelo le tlaase le torque e phahameng, matla a mangata a mangata
Ka kakaretso, mokhanni oa servo o na le matla a mangata a fetang 1.5 ka metsotso e seng mekae kapa halofo ea hora, 'me a ka imeloa ka makhetlo a 4 ho isa ho a 6 ka nako e khutšoanyane ntle le tšenyo.
6. Ho tšepahala ho phahameng
Hoa hlokahala hore tsamaiso ea phepelo ea lisebelisoa tsa mochini oa CNC e be le ts'epo e phahameng, botsitso bo sebetsang ba ho sebetsa, ho ikamahanya le maemo a matla a tikoloho ho mocheso, mongobo, ho thothomela le matla a matla a ho thibela ho kena-kenana.
Litlhokahalo tsa servo drive bakeng sa enjene:
1. Motlakase o ka matha hantle ho tloha ka lebelo le tlaase ho ea ho lebelo le phahameng ka ho fetisisa, 'me ho fetoha ha torque ho lokela ho ba nyenyane, haholo-holo ka lebelo le tlaase joaloka 0.1r / min kapa ka tlaase, ho ntse ho e-na le lebelo le tsitsitseng ntle le ho khasa.
2. Motlakase o lokela ho ba le matla a mangata a mangata ka nako e telele ho finyella litlhoko tsa lebelo le tlaase le torque e phahameng.Ka kakaretso, li-motors tsa DC servo li tlameha ho tlatsoa makhetlo a 4 ho isa ho a 6 ka metsotso e seng mekae ntle le tšenyo.
3. E le ho finyella litlhoko tsa karabelo e potlakileng, motlakase o lokela ho ba le nako e nyenyane ea inertia le torque e kholo ea stall, 'me e be le nako e nyenyane e tsitsitseng le ho qala motlakase ka hohle kamoo ho ka khonehang.
4. Enjene e lokela ho khona ho mamella ho qala khafetsa, ho qhoqhoa le ho potoloha ka morao.
