Amakhasimende aphelele azuza ekusebenzeni okungaguquki kuwo wonke ama-batches, abhalwe phansi amapharamitha kagesi nama-mehendi, kanye nokusekelwa kokuhlanganiswa kokuphepha - izindawo ezikalwe futhi ezihlangenwe nakho lapho ukuthembeka nokuphindwayo kungenjalo -

Ukukhetha, ukucubungula nokusetshenziswa okusebenzayo

Ukukhetha usayizi wezimoto, i-voltage, kanye nohlobo lokushayela

Ukukhetha i-loop ye-loop evaliwe yangakwesokudla kufaka i-torque, ijubane, kanye nezidingo ze-inertia. Abaqambi bavame ukuqala kusuka kulayini odingekayo we-Linear noma i-Rotary Motion bese ubale i-torque ye-j · Jeα, lapho i-j Isibonelo, ukuhambisa umthwalo we-0.5 kg esikuluyeni okuholela ku-10 mm ku-500 mm / s ngokusheshisa okungu-1 000 MM / S² kungadinga i-torque ephakeme ebangeni le-0.5-1.0 N · m. I-Supply Voltage ithinta ukuphakama - I-Speed ​​Torque: Uhlelo lwe-48 v ngokuvamile lunikeza ukusebenza okungcono ku-1,000 RPM nangaphezulu kohlelo lwe-24 v, ngoba ivolumu ephakeme linqoba i-coil extance ngempumelelo.

Ukuhamba Kokusebenza Kokusebenza Kokusebenza Nepharamitha

Ukuhlelwa ngokujwayelekile kuqala ngemikhawulo yamanje yokulondolozwa kanye nokusheshisa okulinganiselwe, kulandelwe ukwenyuka okukhuphukayo ngenkathi kubhekwa iphutha lesikhundla kanye nokushisa. Amapharamitha afana nesikhundla sokuthola inzuzo, ukuphendula kwe-velocity, kanye nemikhawulo yejerk yakha impendulo enyakazayo. Ama-Drive amaningi ahlinzeka ngamathuluzi wesoftware wokuqapha isikhundla, isivinini, nawamanje. Umkhuba omuhle ukuqinisekisa ukuthi i-Peak yamanje ngesikhathi sokuhamba okusheshayo ihlala ngaphansi cishe kwe-120-150% yamanje futhi eliqinile lokushisa lemoto lihlala ngaphansi kuka-70-80 ° C ekusebenzeni okuqhubekayo. Lokhu kuqinisekisa ukumaka okwanele kokuhlukahluka okukhona futhi kunwetshwe isikhathi eside.

Ukuhlanganiswa, izintambo, kanye nokucatshangelwa kwe-EMC

Ukusebenza okuthembekile kudinga ukunakekelwa e-wiring nakusisekelo. Izintambo ze-encod Kusetshenziswa ngababili okusontekile nokuqedwa okufanele kusiza ukugcina ubuqotho besiginali ngesivinini esikhulu kanye namafrikhi encoder. Ukuxhumeka komhlaba okuvikelekile kwedrayivu kufanele kube ukungcola okuphansi, futhi izizathu zokulawula kufanele zihlelwe ukuvikela izihibe zomhlaba. Ngezinhlelo ezithe xaxa kanye ne-OEM ezihanjiswe emhlabeni wonke, ukuhambisana namazinga we-EMC kanye nokuphepha kubalulekile, okuvame ukubandakanya izihlungi zokufaka, ama-Ferrite cores, kanye nesakhiwo ngokucophelela sokusatshalaliswa kwamandla nemigqa yokuxhumana.

UMaxtech uhlinzeka ngezisombululo

UMaxtech unikeza izixazululo eziphelele zokuvimbela izixazululo ze-loop ezihlanganisa ukuphakama - i-torque hybrid motors, ukuphakama - ama-encodcters atholakalayo, kanye nokushayela okuqondayo ngama-algorithms athuthukile. Noma ngabe ungumkhiqizi oklama imishini entsha ezenzakalelayo, noma umlingani we-persolealed osebenzela izimakethe zesifunda, ukuhlanganiswa okuhambisana nokushayela kusuka ephansi - Amandla Nema 17 kuya phezulu - iTorque NEMA 34 nangaphezulu. Iqembu lethu lobunjiniyela lisekela ukubalwa kwesivinini se-torque, ukuhlaziya i-inertia, kanye ne-drive parameter tuning, ukuqinisekisa ukuthi ama-axes akho athola okunembile, ukusebenza okuthembekile ngokusetshenziswa kwamandla okulungiselelwe kwezimboni.
