I-hub motor eqhelekileyo yi-DC brushless motor, kwaye indlela yokulawula iyafana naleyo ye-servo motor.Kodwa ubume be-hub motor kunye ne-servo motor ayifani ncam, eyenza indlela eqhelekileyo yokukhetha i-servo motor ingasebenzi ngokupheleleyo kwi-hub motor.Ngoku, makhe sijonge indlela yokukhetha i-hub motor efanelekileyo.
I-hub motor ithiywa ngokwesakhiwo sayo, kwaye ihlala ibizwa ngokuba yi-rotor yangaphandle ye-DC brushless motor.Umahluko ukusuka kwi-servo motor kukuba indawo ehambelana ne-rotor kunye ne-stator iyahluka.Njengoko igama lithetha, i-rotor ye-hub motor ifumaneka kumda we-stator.Ke xa kuthelekiswa ne-servo motor, i-hub motor inokuvelisa i-torque engaphezulu, emisela ukuba indawo yesicelo se-hub motor kufuneka ibe ngoomatshini abanesantya esiphantsi kunye ne-torque ephezulu, njengeshishini leerobhothi ezishushu.
Xa uyila inkqubo ye-servo, emva kokukhetha uhlobo lwenkqubo ye-servo, kuyimfuneko ukukhetha i-actuator.Kwinkqubo ye-servo yombane, kuyimfuneko ukugqiba imodeli ye-servo motor ngokomthwalo wenkqubo ye-servo.Le yingxaki ehambelanayo phakathi kwe-servo motor kunye nomthwalo womatshini, oko kukuthi, ukuyila indlela yamandla yenkqubo ye-servo.Ukumataniswa kwe-servo motor kunye nomthwalo womatshini ikakhulu kubhekiselele ekufaniseni inertia, umthamo kunye nesantya.Nangona kunjalo, ekukhethweni kwee-servo hubs, intsingiselo yamandla iyancipha.Ezona zalathisi zibalulekileyo yitorque kunye nesantya, imithwalo eyahlukeneyo kunye nokusetyenziswa okwahlukileyo kwe-servo hub motor.Indlela yokukhetha i-torque kunye nesantya?
1.Ubunzima benjini yehabhu
Ngokuqhelekileyo, iirobhothi zenkonzo ziya kukhethwa ngobunzima.Ubunzima apha bubhekisela kubunzima obupheleleyo berobhothi yenkonzo (i-robot self-weight + weight load).Ngokuqhelekileyo, kufuneka siqinisekise ubunzima obupheleleyo ngaphambi kokuba senze ukhetho.Ubunzima benjini buchongiwe, ngokwesiseko iiparamitha eziqhelekileyo ezifana netorque zimiselwe.Ngenxa yokuba ubunzima bunciphisa ubunzima bezinto zangaphakathi zamagnetic, ezichaphazela i-torque ye-motor.
2.Isakhono sokulayisha ngaphezulu
I-angle yokunyuka kunye nokukwazi ukunyuka phezu kwemiqobo nayo isalathisi esibalulekileyo ekukhethweni kweerobhothi zenkonzo.Xa ukhuphuka, kuya kubakho i-gravitational component (Gcosθ) eyenza i-robot yenkonzo idinga ukunqoba umsebenzi, kwaye kufuneka ikhuphe i-torque enkulu;ngendlela efanayo, i-angle ye-tilt nayo iya kwenziwa xa ukhwela i-ridge.Kwakhona kufuneka ukoyise umxhuzulane wokwenza umsebenzi, ngoko ke amandla okulayisha ngaphezulu (oko kukuthi, i-torque ephezulu) iya kuchaphazela kakhulu amandla okunyuka umqolo.
3.Isantya sesantya
Ukubaluleka kokugxininisa iparameter yesantya esilinganisiweyo apha kukuba ihluke kwiimeko zokusetyenziswa kweemoto eziqhelekileyo.Umzekelo, inkqubo ye-servo ihlala isebenzisa imotor + isinciphisi ukufumana itorque enkulu.Nangona kunjalo, i-torque ye-hub motor ngokwayo inkulu, ngoko ke ukusebenzisa i-torque ehambelanayo xa idlula isantya sayo esilinganisiweyo kuya kubangela ilahleko enkulu, okukhokelela ekugqithiseni okanye kumonakalo kwi-motor, ngoko ke kuyimfuneko ukunikela ingqalelo kwisantya sayo esilinganisiweyo.Ngokuqhelekileyo ilawulwa ngaphakathi kwamaxesha e-1.5 ukuya kumthamo wayo wokufumana iziphumo ezilungileyo.
Ukususela ekusekweni kwayo, i-Shenzhen Zhongling Technology Co., Ltd. igxile kwi-R & D, imveliso kunye nokusebenza kakuhle kweenjini ze-hub, ukubonelela abathengi ngeemveliso zodidi lokuqala kunye nezisombululo kunye nemilinganiselo yokugxila, ukuveliswa kwezinto ezintsha, ukuziphatha kunye nepragmatism.
