Tsarin kayan aikin wutar lantarki na yau da kullun sun haɗa da rotor na mota (shaft, rotor core, winding), stator (stator core, stator winding, akwatin mahaɗi, murfin ƙarshe, murfin bearing, da sauransu) da sassan haɗawa (bearing, hatimi, carbon goga, da sauransu) da sauran manyan sassan. A cikin dukkan sassan tsarin motar, wasu shaft na bear da radial load amma ba su da nasu motsi na ciki na dangi; Wasu daga cikin motsin ciki na dangi bayan amma ba sa ɗaukar axis, radial load. Bearings kawai suna ɗaukar nauyin shaft da radial yayin motsi dangane da juna a ciki (dangane da zoben ciki, zoben waje da jikin birgima).
