Tshi halaye na DD motor

1, Tsarin motar DD yana cikin nau'i na rotor na waje, wanda ya bambanta da AC servo na tsarin rotor na ciki.Adadin sandunan maganadisu a cikin motar shima yana da girman gaske, yana haifar da mafi girman farawa da jujjuyawa.

2, Radial bearing da aka yi amfani da shi a cikin motar na iya ɗaukar ƙarfin axial mai girma.

3, The encoder ne mai high ƙuduri madauwari grating.Ƙimar grating madauwari da motar jDS DD ke amfani da ita shine 2,097,152ppr, kuma yana da asali da ƙayyadaddun fitarwa.

4, Saboda ma'aunin ma'auni mai mahimmanci da tsarin masana'antu masu girma, daidaitattun matsayi na motar DD na iya isa matakin na biyu.(Misali, cikakken daidaiton jerin DME5A shine ± 25arc-sec, kuma daidaiton matsayi mai maimaita shine ± 1arc-sec)

Motar DD da servo motor + mai ragewa suna da bambance-bambance masu zuwa:

1: Babban hanzari.

2: Babban karfin juyi (har zuwa 500Nm).

3: Babban madaidaici, babu sako-sako na shaft, ana iya samun ikon sarrafa matsayi mai mahimmanci (mafi girman maimaitawa shine 1 na biyu).

4: Babban daidaito na inji, motar axial da radial runout na iya kaiwa cikin 10um.

5: Babban kaya, motar zata iya ɗaukar har zuwa 4000kg na matsa lamba a cikin axial da radial kwatance.

6: Babban tsauri, mai ƙarfi mai ƙarfi don radial da ɗaukar nauyi.

7: Motar tana da ramin rami don sauƙi na igiyoyi da bututun iska.

8: Babu kulawa, tsawon rai.

Jawabin

Motoci na DDR yawanci suna amfani da ra'ayoyin ƙara ƙarar gani.Duk da haka, akwai kuma wasu nau'ikan ra'ayoyin da za a zaɓa daga, kamar: mai rikodin rikodin, cikakken encoder da inductive encoder.Maɓallan gani na gani na iya samar da ingantacciyar daidaito da ƙuduri mafi girma fiye da encoders masu warwarewa.Ba tare da la'akari da girman babban injin DDR na babban lokaci ba, filin ƙwanƙwasa na mai sarrafa kayan sawa na gani yawanci microns 20 ne.Ta hanyar shiga tsakani, ana iya samun ƙuduri mai tsayi sosai don cimma daidaiton da aikace-aikacen ke buƙata.Misali: DME3H-030, filin grating shine 20 microns, akwai layin 12000 a kowace juyin juya hali, madaidaicin girman girman interpolation shine sau 40, kuma ƙuduri akan kowane juyin shine raka'a 480000, ko ƙuduri tare da grating kamar yadda martani shine 0.5 microns.Amfani da SINCOS (analog encoder), bayan sau 4096 na interpolation, ƙudurin da za'a iya samu shine raka'a 49152000 a kowace juyin juya hali, ko ƙuduri tare da grating azaman martani shine 5 nanometers.
