Ni ubuhe buryo bwo guhangana na stator ihindagurika ya moteri y'ibyiciro bitatu idafite moteri ikwiye gufatwa nkibisanzwe bitewe n'ubushobozi?(Kubijyanye no gukoresha ikiraro no kubara guhangana ukurikije diameter ya wire, ntabwo bidashoboka.) Kuri moteri iri munsi ya 10KW, multimeter ipima gusa oms nkeya.Kuri 55KW, multimeter yerekana icya cumi.Irengagize reaction ya inductive kuri ubu.Kuri moteri ya 3kw ihuza moteri, multimeter ipima kwihanganira guhindagurika kuri buri cyiciro kuba hafi ya oms 5 (ukurikije icyapa cyerekana moteri, ikigezweho: 5.5A. Impamvu zingufu = 0.8. Birashobora kubarwa ko Z = 40 oms, R = 32 oms).Itandukaniro riri hagati yombi naryo ni rinini cyane.

Kuva moteri itangira kugeza mugihe cyambere cyo gukora imitwaro yuzuye, moteri ikora mugihe gito kandi ubushyuhe ntabwo buri hejuru.Nyuma yo gukora isaha 1, ubushyuhe busanzwe buzamuka Kugera kurwego runaka, imbaraga za moteri zizagabanuka cyane nyuma yisaha imwe?Ikigaragara ni uko!Hano, nizere ko inshuti zamashanyarazi zifite uburambe zishobora kwerekana uburyo ubipima.Inshuti nazo zayobewe mugihe cyo gusana moteri zirashobora gusangira uko ubyumva?

Ongeraho ifoto kugirango urebe:

Kurwanya ibyiciro bitatu bizunguruka bya moteri bipimwa kuburyo bukurikira:

1. Kuramo igice gihuza hagati ya moteri.

2. Koresha urwego ruto-rudasanzwe rwa digitale ya digitale kugirango upime guhangana nintangiriro nimpera yimyenda itatu ya moteri.Mubihe bisanzwe, kurwanya imirongo itatu bigomba kuba bingana.Niba hari ikosa, ikosa ntirishobora kurenga 5%.

3. Niba moteri irwanya moteri irenze 1 ohm, irashobora gupimwa nikiraro cyamaboko imwe.Niba moteri irwanya moteri iri munsi ya 1 ohm, irashobora gupimwa nikiraro cyamaboko abiri.

Niba hari itandukaniro rinini mukurwanya hagati ya moteri, bivuze ko guhinduranya moteri bifite imiyoboro migufi, imiyoboro ifunguye, gusudira nabi hamwe namakosa mumibare ihindagurika.

4. Kurwanya insulasiyo hagati yumuyaga no kurwanya insulasi hagati yizunguruka nigikonoshwa bishobora gupimwa na:

1) Moteri ya 380V ipimwa na megohmmeter ifite intera ingana na megohms 0-500 cyangwa megohms 0-1000.Kurwanya insulasiyo ntishobora kuba munsi ya megohms 0.5.

2) Koresha megohmmeter ifite urugero rwa megohm 0-2000 kugirango upime moteri yumuriro mwinshi.Kurwanya insulasiyo ntishobora kuba munsi ya megohms 10-20.
