No nā motika asynchronous, ʻo ka slip kahi kūlana kūpono no ka hana ʻana o ke kaʻa, ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o ka wikiwiki o ka rotor ma mua o ka wikiwiki o ke kahua magnetic rotating. No ka moto synchronous, e hoomau mau ana na kahua magnetic o ka stator a me ka rotor i ka holo like, oia hoi, ua like ka holo o ka holo ana o ke kaa me ka mämä holo.
Mai ka nānā ʻana, ʻaʻole ʻokoʻa ka ʻōnaehana stator o ka mīkini synchronous mai ka mīkini asynchronous.Ke hoʻokomo ʻia kahi ʻano ʻekolu i loko, e hoʻokumu ʻia kahi māla magnetic rotating synchronous; ʻO ka ʻāpana rotor o ka kaʻa he sinusoidally distributed magnetic field of DC excitation, hiki ke hana ʻia e nā magnet mau loa.
Ke holo maʻamau ka kaʻa, ua kūlike ka wikiwiki o ka mākia rotor me ka wikiwiki o ka stator magnetic field, ʻo ia hoʻi, paʻa ka stator a me ka rotor magnetic field i ka lewa, ʻo ia ke ʻano synchronous o ka synchronous. kaʻa kaʻa. Ke kū ʻole nā mea ʻelua, ua manaʻo ʻia ʻo ke kaʻa i waho o ka pae.
Ke lawe nei i ka rotation direction o ka rotor ma ke ʻano he kuhikuhi, i ka wā e alakaʻi ai ka mākia rotor i ka stator magnetic field, hiki ke hoʻomaopopo ʻia ʻo ia ka mana o ka rotor magnetic field, ʻo ia hoʻi, ka hoʻololi ʻana o ka ikehu ma lalo o ka hana o ka mana, ʻo ka motor synchronous. ka mokuahi generator; ma ka ʻaoʻao ʻē aʻe, ʻo ke ʻano o ka rotation o ka rotor kaʻa no ka ʻike ʻana, i ka wā e waiho ana ka māhina rotor ma hope o ke kahua magnet stator, hiki iā mākou ke hoʻomaopopo i ka huki ʻana o ka mākēne stator i ka rotor e neʻe, a aia ke kaʻa i kahi mokuʻāina. .I ka wā o ka hana ʻana o ke kaʻa, ke piʻi aʻe ka ukana i huki ʻia e ka rotor, e hoʻonui ʻia ka lag o ka mākēneki rotor e pili ana i ke kahua magnetic stator. Hiki i ka nui o ke kaʻa ke hōʻike i ka mana o ke kaʻa, ʻo ia hoʻi, ma lalo o ka volta helu helu like a me ka manawa i helu ʻia, ʻoi aku ka nui o ka mana, ʻoi aku ka nui o ke kihi mana e pili ana.
Inā ʻo ka mokuahi kaʻa a i ʻole ka moku hana, inā ʻaʻohe ukana o ka kaʻa, ʻaʻohe ʻano o ka mana theoretical, ʻo ia hoʻi, ʻokoʻa loa nā māla magnetic ʻelua, akā ʻo ke kūlana maoli ma muli o kekahi mau poho o ka kaʻa. , aia nō kahi kihi mana ma waena o lāua. Loaʻa, ʻoi aku ka liʻiliʻi.
I ka wā ʻaʻole i hoʻonohonoho ʻia nā māla magnetic rotor a me stator, hoʻololi ke kihi mana o ke kaʻa.Ke waiho ka rotor ma hope o ka stator magnetic field, hoʻopuka ka stator magnetic field i ka ikaika hoʻokele i ka rotor; i ka wā e alakaʻi ai ke kahua mākēneki rotor i ke kahua mākēneki stator, hoʻopuka ke kahua mākēne stator i ke kūʻē ʻana i ka rotor, no laila ʻaʻole ka awelika torque.No ka mea ʻaʻole loaʻa i ka rotor ka torque a me ka mana, hiki mai ia i kahi lohi.
Ke holo nei kekahi kaʻa kaʻa synchronous, e hoʻohuli ke kahua mākēne stator i ka māhina rotor e hoʻohuli.Aia kahi torque paʻa ma waena o nā māla magnetic ʻelua, a ua like ka wikiwiki o ka huli ʻana o nā mea ʻelua.ʻAʻole like ka māmā holo o nā mea ʻelua, ʻaʻole i loaʻa ka torque synchronous, a kū mālie ke kaʻa.ʻAʻole like ka wikiwiki o ka rotor me ka stator magnetic field, no laila e nalowale ka torque synchronous a kū mālie ka rotor, i kapa ʻia ʻo "out-of-step phenomenon".I ka wā e puka mai ai ka hanana ma waho, pi'i koke ke au o ka stator, he mea maika'i 'ole ia. Pono e ʻoki ʻia ka mana i ka hikiwawe e pale aku i ka pōʻino o ke kaʻa.
