Kusiyana kwakukulu pakati pa ma synchronous motors opangidwa ndi LT SIMO Motorndi wambama asynchronous motors TDMK Motormu ntchito ndi kuti pamene galimoto synchronous ikuyenda, ngodya pakati pa armature voteji vekitala ndi rotor pole udindo ayenera kukhala mu osiyanasiyana osiyanasiyana, apo ayi dongosolo adzataya sitepe. Chifukwa chake, injini ya synchronous ikasinthidwa pafupipafupi ndikuwongolera liwiro, ngodya iyi iyenera kuyendetsedwa nthawi zonse kuti isinthe mkati mwazovomerezeka. Ichi ndiye kusiyana kwakukulu pakati pa synchronous motor frequency kutembenuka ndi asynchronous motor frequency kutembenuka. Zotsatirazi zifotokoza mwachidule zovuta zomwe zimakumana nazo mumotor synchronous frequency kutembenuka liwiro lamulondondomeko ndi mayankho ofanana a maxf pafupipafupi kutembenuka chipangizo:
Synchronous motor kuyambira ndi njira yosangalatsa
Nthawi zambiri pali njira ziwiri zoyambira mota ya asynchronous: imodzi ndiyo kusangalatsa koyamba ndikuyamba synchronously; chinacho ndi kuyamba mwachisawawa ndiyeno kusangalala ndi polarity yomweyo. Pakutembenuka kwa ma frequency a synchronous motor kuyambira, kusangalatsa kumagwiritsidwa ntchito koyamba ndikuyambira molumikizana, koma kuweruza kolakwika kwa rotor nthawi zambiri kumabweretsa kulephera kwa injini. Pakuti synchronous galimoto pafupipafupi kutembenuka liwiro lamulo, n'zosavuta kutengera asynchronous kuyambira ndi patsogolo polarity chisangalalo. Chifukwa chake, chipangizo chosinthira ma frequency maxf chimachita mofewa mopanda tsankho kuyambira pa injini yolumikizana kuti ikwaniritse torque yoyambira, ndikuyambitsa injini yolumikizirana mpaka pafupifupi 8hz kuti ipititse patsogolo polarity. Kukula kwachisangalalo ndi kuchuluka kwachisangalalo kumatha kusinthidwa ndikutsimikiziridwa malinga ndi nthawi zosiyanasiyana zogwiritsira ntchito. Panthawi imeneyi, pambuyo ngodya pakati pa galimoto rotor maginito ndi stator maginito ndi pang'ono oscillation wonyowa, galimoto rotor maginito pole ndi modalirika anakopeka ndi stator maginito pole, ndi galimoto synchronous akulowa synchronous ntchito boma. The inverter pang'onopang'ono imathandizira kufupipafupi kupatsidwa malinga ndi mathamangitsidwe omwe adakonzedweratu. Panthawi imeneyi, ngodya pakati synchronous galimoto armature voteji vekitala ndi ozungulira maginito mzati udindo pang'onopang'ono kumawonjezera mtengo zina zonse, ndi galimoto rotor maginito mzati pang'onopang'ono inapita patsogolo kwa liwiro ankafuna pansi kukopa kwa stator maginito, ndi synchronous galimoto kuyambira ndondomeko yatha.
