Wiper motor imayendetsedwa ndi mota, ndipo kusuntha kozungulira kwa mota kumasinthidwa kukhala kubwereza kwa mkono wopukutira kudzera pamakina olumikizira ndodo, kuti muzindikire zomwe zimachitika. Nthawi zambiri, injini imatha kulumikizidwa kuti wiper igwire ntchito. Posankha kuthamanga kwambiri komanso kuthamanga pang'ono, mphamvu yamotoyo imatha kusinthidwa, kuti muzitha kuyendetsa liwiro lagalimoto ndikuwongolera liwiro la mkono wa wiper. Wiper motor imatenga mawonekedwe atatu a burashi kuti athandizire kusintha liwiro. Nthawi yapakatikati imayang'aniridwa ndi relay yapakatikati, ndipo chopukutiracho chimakankhidwa molingana ndi nthawi inayake ndi chiwongolero ndi kutulutsa ntchito yolumikizirana ndikusinthana kwagalimoto ndi mphamvu yolumikizirana.
Kumapeto kumbuyo kwa wiper galimoto ndi kagawo kakang'ono ka gear komwe kamakhala m'nyumba yomweyi, yomwe imachepetsa kuthamanga kwa liwiro lofunikira. Chipangizochi chimadziwika kuti wiper drive assembly. Mtsinje wotuluka wa msonkhano umagwirizanitsidwa ndi makina opangira mapeto a wiper, omwe amazindikira kugwedezeka kobwerezabwereza kwa wiper kudzera pa foloko ndi kubwerera kwa masika.
Wiper blade ndi chida chochotsera mvula ndi dothi mwachindunji kuchokera pagalasi. Mzere wa mphira wopukutira umakanikizidwa pamwamba pa galasi kudzera pa bar ya masika, ndipo milomo yake iyenera kukhala yogwirizana ndi Angle ya galasi kuti ikwaniritse zofunikira. Nthawi zambiri, pali chopukuta pa chogwirira cha cholumikizira chophatikizira chagalimoto kuti chiwongolere kupotoza, ndipo pali magiya atatu: liwiro lotsika, liwilo lalikulu komanso lapakati. Pamwamba pa chogwiriracho pali chosinthira chachikulu cha scrubber. Pamene chosinthiracho chikanikizidwa, madzi ochapira adzatulutsidwa, ndipo galasi la mphepo la makina ochapira a wiper lidzafanana.
Zofunikira zamtundu wa wiper motor ndizokwera kwambiri. Imatengera maginito okhazikika a DC. Wiper motor yomwe imayikidwa pagalasi lakutsogolo lamphepo nthawi zambiri imaphatikizidwa ndi gawo lamakina a mphutsi ndi nyongolotsi. Ntchito ya zida za nyongolotsi ndi makina a nyongolotsi ndikuchepetsa ndikuwonjezera ma torsion. Shaft yake yotulutsa imayendetsa makina olumikizira anayi, momwe kusuntha kosalekeza kumasinthidwa kupita kumanzere kumanja.
