Lerata la li-motors tsa motlakase le ka aroloa ka mekhahlelo e meraro: mehloli ea lerata ea aerodynamic, mechanical le electromagnetic lerata. Lilemong tsa morao tjena, batho ba 'nile ba ela hloko haholoanyane tšusumetso ea mehloli ea lerata ea motlakase. Sena se bakoa haholo ke mabaka a mabeli: (a) bakeng sa li-motor tse nyane le tse mahareng, haholo-holo li-motors tse lekantsoeng ka tlase ho 1.5kW, lerata la motlakase le laola sebaka sa acoustic; (b) mofuta ona oa lerata o bakoa haholo-holo ke bothata ba ho fetola thepa ea makenete ea enjene hang ha e etsoa.
Lithutong tse fetileng, phello ea lintlha tse fapaneng lerata la enjene e 'nile ea hlahlojoa ka bophara, joalo ka phello ea pulse wide modulation current on the acoustic lerata boitšoaro ba ka hare magnet permanent synchronous motor drives; phello ea windings, liforeimi le impregnation ka stator resonant frequency; phello ea core clamping khatello, windings, wedges, leino sebopeho, mocheso, joalo-joalo ka vibration boitšoaro ba stator ea mefuta e fapaneng ya Motors.

Ba hahile mefuta ea CAD e ipapisitseng le boholo ba jometri le thepa ea thepa ea enjene ea 'nete,' me mohlala oa litšupiso e le 4-pole, 12-slot Interior magnet synchronous motor (IPMSM).
