Is féidir go ndéantar damáiste do mhótar líonra leictreach sa phróiseas a bhaineann le húsáid a bhaint as an mbord sreangaithe bloc teirminéil, agus ansin ní féidir idirdhealú a dhéanamh idir sé chríochfort agus comhtháthú an naisc foirceanta inmheánaigh, roinneann an páipéar seo an modh ilmhéadar go AC agus DC an oibríocht mhionsonraithe ar thús agus deireadh an mhótair foirceanta trí chéim a aithint. 1, idirdhealú an dá chríochfort foirceanta den mhótair le foirceannadh trí chéim, tá dhá chríochfort ag gach céim foirceanta, idirdhealú gach céim críochfoirt foirceanta OHM ilmhéadar infheidhme. Cuir an ilmhéadar R × 10Ω, ag tomhas dhá chríochfort ar bith den fhriotaíocht sa bhosca teirminéil mótair, má tá an fhriotaíocht an -bheag, taispeáin an dá chríochfort reatha de chríochfort céimnithe, bain úsáid as an modh céanna chun teacht ar an gcríochfort foirceanta dhá chéim eile, mar sin tá an t -am ar fad ag an gcríochfort de réir mar a mhaolaíonn an dá ghrúpa eile de réir mar a mhaolaíonn an dá ghrúpa eile de chuid Terminals. 2, Ní féidir idirdhealú a dhéanamh idir an chéim eireaball foirceanta den chéad mhótar, agus ní féidir idirdhealú a dhéanamh idir an chéim U, V, W, ach i ndeireadh gach céime tá gá le foirceannadh chun idirdhealú a dhéanamh. An chéad cheann idirdhealaitheach den bhealach a úsáidtear go coitianta chun modh foirceanta DC agus modh cumarsáide a bheith agat. 1) Modh DC chun an chéad cheann den fhoirceannadh trí chéim a mheas sa difríocht idir deireadh céim ag foirceannadh ar dtús trí mhodh DC a chur i bhfeidhm, is gá an dá chríochfort foirceanta a fháil amach. Dc method first discriminant winding end puts multimeter minimum dc current file, red, black pens and separation by a group of two terminals of the winding, and then to the other one phase winding two terminals of the battery and switch, switch on, at the instant of the switch is closed, if the clock right swing, indicate the battery terminals and red pens and the anode receive receive terminal for side (with the sameBattery cathode by the terminal and terminal for Taobh leis na pinn dhubh chéanna agus faigh, má luann an clog ar chlé, tabhair le fios go léiríonn críochfoirt na gcríochfort diúltach ceallraí agus na pinn dhearga agus go bhfaigheann tú deireadh, leis an bhfigiúr céanna a bhfuil an luascán ceart ina lámha, léiríonn deireadh an WA le deireadh UA go deireadh, agus an t -athrú céanna arís, ag baint úsáide as dhá phinn agus piocadh suas ceann de na dhá théarma atá fágtha den fhoirceannadh, ag baint úsáide as an modh céanna chun an chéim a bhaint amach. Sainaithin gach céim ag foirceannadh tar éis dheireadh an ainm chéanna, beidh an cineál céanna trí dheireadh leis an ainm céanna leis an gceann foirceanta, an chuid eile de na trí chríochfort don deireadh foirceanta. Mar gheall ar an bhfriotaíocht foirceanta mótair tá sé beag, athraigh an t -am dúnta nach bhfuil ró -fhada, chun an ceallraí a rith amach nó a dhó amach. Dc method judging winding end with the same principle is: when closing switch moment, W winding electromotive force, arising from Russia but have a current through the electromotive force polarity for Wa, Wb negative, because the other two phase winding and within easy reach of W phase winding, W on the phase winding is induced electromotive force on the two phase winding, if Ua end with end to end with the same Wa, the Ua the polarity is positive, U phase winding into a circuit with a multimeter, U phase winding of induction electromotive force of the current flow from red pens and multimeter, the clock will swing, right open closed after one period of time, into the W phase winding current basically stable, W phase winding electromotive force was not occurred, the other two phase winding nor inductive electromotive force, multimeter the clock will stop at zero Calabrú. . Communication method to judge winding fore and aft of the two phase winding first link up the two terminals, multimeter under ac voltage, red, black pens and separation after the two phase winding of the other two terminals, and then to the rest of the phase windings to light bulbs and 220 v ac power, if the clock is marked by voltage indicator, red, black pens and pick up the two terminal end (for different nameLink up the two terminals are same Taobh) ag athrú foirceanta arís, an bhfuil an tástáil thuas, léiríonn ilmhéadar luach voltais 0, ag léiriú UBWA ar thaobh (leis an rud céanna ar thaobh) leis an rud céanna。 Sainaithin gach céim foirceanta tar éis dheireadh na dtrí cinn de na trí théarma ag deireadh na foircinn. Communication method of judging the principle is: the same name as the 220 v ac voltage by the bulb step-down to a phase winding, the other two phase winding induction voltage, if the two phase winding is end with different end link up with the same name, the superposition of two voltage on the phase winding increases one times, multimeter can have voltage indicator, if the two windings is end with the same name with the same cohesion, Cuirfidh maolú dhá voltas ar an gcéim foirceanta a chéile ar ceal, is é 0 voltas tomhaiste ilmhéadar.
