3 Njira zowongolera zomwe zimagwiritsidwa ntchito mu servo motor

Ma Servo motors nthawi zambiri amawongoleredwa ndi mabwalo atatu, omwe ndi njira zitatu zotsekera zowongolera zolakwika za PID. Dera la PID ndiye dera lomwe lilipo ndipo limakhazikitsidwa mkati mwawowongolera wa servo. Kutulutsa komweku kuchokera kwa wowongolera kupita ku mota kumatengera cheke cha zinthu za Hall, mayankho olakwika omwe amakhazikitsidwa ndi PID, ndipo zomwe zatuluka zimasinthidwa kuti zikhale pafupi kwambiri ndi zomwe zakhazikitsidwa. Dera lapano limayang'anira ma torque, kotero wowongolera amakhala ndi magwiridwe antchito ochepa komanso mayankho osasunthika tsiku lililonse ndipo amayenera kukhala othamanga pamachitidwe owongolera ma torque. Ngakhale pali njira zambiri zowongolera zomwe zikupezeka mu servo motor, Gator Precision, imodzi mwa China top 10mafakitale opangira ma rotorkuphatikiza kupanga nkhungu, masitampu achitsulo cha silicon, kusonkhanitsa magalimoto, kupanga ndi kugulitsa, apa tilankhula za njira zitatu zowongolera zomwe zimagwiritsidwa ntchito kwambiri mu injini ya servo.

Mitundu yayikulu yowongolera mu servo motor imaphatikiza ma torque control mode, mawonekedwe owongolera ndi liwiro.

1. Torque control mode. Munjira iyi, torque yotulutsa ya shaft yamoto imayikidwa kudzera pakulowetsa kwa analogi kapena kugawa adilesi mwachindunji. Mwachitsanzo, torque linanena bungwe shaft galimoto ndi 2.5Nm pamene analogi kunja wakhazikitsidwa 5V. Pamene galimoto imazungulira ndi katundu wa shaft wosakwana 2.5Nm ndipo katundu wakunja ndi wofanana ndi 2.5nm (pamwamba pa 2.5nm), galimotoyo imakhala yovuta kuzungulira. Pamene servo motor reversets (nthawi zambiri pansi pa katundu wa mphamvu), kukhazikitsidwa kwa kuchuluka kwa analogi kungasinthidwe mu nthawi yeniyeni mwa kusintha makonzedwe a torque kapena kusintha mtengo wa adiresi wachibale malinga ndi kulankhulana.

2. Udindo wowongolera mawonekedwe. Position control mode nthawi zambiri imatanthawuza kuchuluka kwa liwiro kudzera pamaphukusi olowera kunja ndi momwe amawonera kudzera mu kuchuluka kwa ma pulse. Kuthamanga ndi kutsika kwa madalaivala ena a servo motor atha kuperekedwa mwachindunji kudzera mukulankhulana. Munjira iyi, liwiro ndi udindo zitha kuyendetsedwa mosamalitsa, kotero kuti mawonekedwe owongolera malo amagwiritsidwa ntchito poyika ma lathes a CNC ndi zida zosindikizira.

3. Kuthamanga mode. Liwiro limatha kuwongoleredwa motengera kulowetsa kwa analogi kapena pafupipafupi kugunda kwamtundu umodzi. Pamene chiwongolero chakunja cha PID cha chipangizo chowongolera chingagwiritsidwe ntchito, njira yothamanga imathanso kuyimitsidwa, koma onetsetsani kuti mukudyetsa chizindikiro cha data ya mota kapena katundu wolunjika kumtunda wapamwamba kuti agwire ntchito.Makampani oyambira a Servo motor rotorpezani mawonekedwe amtunduwo amagwiranso ntchito kumbali yakunja ya katundu wachindunji kuti ayang'ane chizindikiro cha data, pomwe kuthamanga kwagalimoto kumangoyang'aniridwa kumbali ya servo motor shaft, ndipo chizindikiro cha data chamalo chimaperekedwa ndi chipangizo choyang'ana mwachindunji. katundu mbali. Pochita izi, kupatuka pagalimoto yapakatikati kudzachepetsedwa ndipo kulondola kwadongosolo kwadongosolo lonse kudzakhala bwino.
