O'ZGARMAS TOK ELEKTR DVIGATELINI
O'RGANISH (MODELDA)
Ishning maqsadi: O’zgarmas tok elektr dvigatelining asosiy detallari bilan uning modelini tanishtirish.
Kerakli jihozlar: akkumulator, kalit, ulovchi simlar, o'zgarmas tok elektr dvigateli modelini yig'ish uchun zarur detallar.
Ishningo’rinlanishi:
1. Elektrodvigatel modelin olib, sinchiklab ko’zdan kechiramiz. Dvigatelning qo’zg’luvchan bo’limi, qozg’almas bo’limi, tok keluvchi bo’limlari, kollektori, cho’tkalarining tuzilishini o’rganamiz.
2. Elektrodvigatel modelini o’rganamiz.
3. Tok manbayiga elektrodvigatelni tutashtirib, aylanishini nazorat qilamiz.
Kuchlanishi 1 – 2 V atrofida o’zgartirib, aylanish tezligi o’zgarishini
nazorat qilamiz.
4. Tok manbayi qutblarini almashtirib tutashtiramiz va dvigatel Yakorining aylanish davrini o’zgarishini nazorat qilamiz.
