Brushless DC motors e sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyeletsoa lisebelisoa tsa indasteri, lisebelisoa tsa bongaka le lisebelisoa tsa elektroniki tsa bareki. Karolo e 'ngoe ea bohlokoa ea li-motor tsena ke "magnetic rotor" ea ente, e sebelisetsoang ho fana ka ts'ebetso e nepahetseng le e tšepahalang.
E entsoe ka phofo ea NdFeB le polymer binder e sebetsang hantle haholo, ente e kopantsoeng ea magnetic rotor ke makenete ea ts'ebetso e phahameng e fanang ka thepa e ikhethang ea khoheli le botsitso. Rotor e entsoe ka ente e nang le limakenete sebakeng, e hlahisang moralo o matla, o kopaneng le o sebetsang hantle.
