1. Khetha i-shaker efanelekile: Uma i-voltage elinganiselwe yokusebenza yemoto evivinywayo ingu-380V, khona-ke singakhetha i-shaker engu-500V.
2. Nyakazisa iwashi eliyisicaba, yenza ukuhlolwa kwe-short-circuit, finyeza amapeni okuhlola amabili, bese unyakazisa isikhombi sesibambo eduze no-0 kuhle.
3. Hlukanisa amapeni amabili okuhlola, nyakazisa isibambo, futhi isikhombisi siseduze nokungapheli.
4. Uma ulinganisa, kungcono ukususa ucezu lokuxhuma lwe-motor yesigaba ezintathu, igobolondo igxiliwe, futhi ama-terminals aphansi ama-windings amathathu kufanele ahlanganiswe, U, V, W ukusuka kwesobunxele kuya kwesokudla.
5. Isinyathelo sokuqala: linganisa ukumelana nokufakwa kwe-insulation phakathi kokuphela kokukhishwa kwezigaba ezintathu kanye ne-casing, u-E uthinta i-motor casing, u-L uthinta amatheminali amathathu u-U, V, no-W ngokulandelanayo, nyakazisa isibambo ngokushesha (ama-revolutions angu-120 ngomzuzu), bese ulinda isikhombisi ukuze sizinze ku-infinity Insulation yinhle uma iseduze.
6. Isinyathelo sesi-2: Kala ukwahlukanisa phakathi koxhumene nabo abathathu u-U, V, no-W. Linganisa okokufaka kanye ngababili. Uma amasethi amathathu ezikhombi zedatha wonke engapheli, ukwahlukanisa kuhle.
7. Ingabuye ilinganiswe ngaphandle kokukhipha ucezu lokuxhuma. Lona umehluko phakathi kwezintambo zenkanyezi ne-delta. Ekucushweni kwenkanyezi, ukumelana phakathi kwamaphuzu amathathu u-U, V, W kanye nephuzu elingathathi hlangothi kungalinganiswa. Amaqembu amathathu amanani wokumelana afana. Okuhle, U, V, W amaphuzu amathathu akalwa ngababili, futhi inani lokumelana liyafana lihle. Kunembile kakhulu ukukala inani lokumelana ne-multimeter, futhi ulinganise ukumelana nomhlabathi ngesikhathi esifanayo.
