Eddy ugbu a bụ otu n'ime nnukwu ihe isi ike na ụlọ ọrụ moto nke ga-eme ka okpomọkụ nke magnet na-adịgide adịgide ma kpatara demagnetization, wee metụta ọrụ arụmọrụ nke moto ahụ.
N'ọtụtụ ọnọdụ, mfu eddy ugbu a nke ndọta na-adịgide adịgide dị ala karịa mfu ígwè na mfu ọla kọpa nke moto, mana ọ ga-ebute nnukwu ọnọdụ okpomọkụ n'ime moto na-agba ọsọ na nnukwu ike njupụta moto.
Dị ka o kwesịrị, stator magnetik na rotor magnetik nke PMSM na-atụgharị synchronously, ma ọ bụ dịtụ static, si otú magnets na-adịgide adịgide na-enweghị eddy ugbu a ọnwụ na dị otú ahụ.
