Seri Ba\u011flama<\/span><\/strong><\/h3>\n

Seri motor, armat\u00fcr sarg\u0131lar\u0131na seri ba\u011fl\u0131 alan sarg\u0131lar\u0131na sahiptir. Bu d\u00fczenleme ile y\u00fckteki bir art\u0131\u015f, h\u0131zda bir azalmaya ve geri e.m.f.’de bir d\u00fc\u015f\u00fc\u015fe neden olacakt\u0131r. Bununla birlikte, artan y\u00fck ak\u0131m\u0131 \u015fimdi manyetik alan\u0131 ve dolay\u0131s\u0131yla geri e.m.f.’yi art\u0131racakt\u0131r. Motor sonunda baz\u0131 azalt\u0131lm\u0131\u015f h\u0131z de\u011ferlerinde dengelenecektir. Seri motor h\u0131z\u0131 bu nedenle y\u00fckle \u00f6nemli \u00f6l\u00e7\u00fcde de\u011fi\u015fir.<\/span><\/p>\n

DC kontrol\u00fc motorlar olduk\u00e7a basittir. \u015e\u00f6nt sarg\u0131l\u0131 motor, g\u00f6sterildi\u011fi gibi saha devresinde de\u011fi\u015fken bir dirence sahiptir. Bu, alan bobinlerindeki ve ayr\u0131ca arka emf’deki ak\u0131m\u0131n de\u011fi\u015fmesine izin vererek bir dizi sabit h\u0131z sa\u011flar. Motoru ters \u00e7evirmek i\u00e7in alan ak\u0131m\u0131 beslemesi g\u00f6sterildi\u011fi gibi ters \u00e7evrilir.<\/span><\/p>\n

Bir seri sarg\u0131l\u0131 motor i\u00e7in bir h\u0131z kontrol y\u00f6ntemi, alan bobinlerine paralel olarak de\u011fi\u015fken bir dirence sahiptir. Ters \u00e7al\u0131\u015fma, g\u00f6sterildi\u011fi gibi alan ak\u0131m\u0131 beslemesinin ters \u00e7evrilmesiyle tekrar elde edilir.<\/span><\/p>\n

\u00c7al\u0131\u015fma s\u0131ras\u0131nda \u015f\u00f6nt sarg\u0131l\u0131 motor, y\u00fckten ba\u011f\u0131ms\u0131z olarak sabit h\u0131zda \u00e7al\u0131\u015f\u0131r. Seri motor y\u00fck taraf\u0131ndan belirlenen bir h\u0131zda \u00e7al\u0131\u015f\u0131r, y\u00fck ne kadar b\u00fcy\u00fckse h\u0131z o kadar yava\u015f olur.

Ba\u015flang\u0131\u00e7 torku da \u00f6nemlidir. Seri sarg\u0131l\u0131 bir motor i\u00e7in ba\u015flang\u0131\u00e7 torku y\u00fcksektir ve y\u00fck artt\u0131k\u00e7a azal\u0131r. Bu, seri motoru vin\u00e7 ve vin\u00e7 uygulamalar\u0131 i\u00e7in kullan\u0131\u015fl\u0131 k\u0131lar. Y\u00fcks\u00fcz olarak \u00e7al\u0131\u015ft\u0131r\u0131lan bir seri motorun sonsuz bir h\u0131za sahip oldu\u011funa dikkat edilmelidir.<\/span><\/p>\n

Bu tehlikeli olaydan ka\u00e7\u0131nmak i\u00e7in az miktarda birle\u015ftirme ola\u011fand\u0131r. \u015e\u00f6nt sarg\u0131l\u0131 motor, y\u00fckten ba\u011f\u0131ms\u0131z olarak sabit h\u0131z\u0131n gerekli oldu\u011fu yerlerde kullan\u0131l\u0131r; \u00f6rne\u011fin, fanlar veya pompalar ile. bir d.c.’nin ba\u015flang\u0131c\u0131 motor, armat\u00fcr ak\u0131m\u0131n\u0131 s\u0131n\u0131rlamak i\u00e7in bir devre d\u00fczenlemesi gerektirir. Bu, bir ba\u015flat\u0131c\u0131 kullan\u0131larak elde edilir.<\/span><\/p>\n

Armat\u00fcrde bir dizi diren\u00e7 sa\u011flan\u0131r ve motor h\u0131zland\u0131k\u00e7a ve e.m.f.’yi geri ald\u0131k\u00e7a kademeli olarak kald\u0131r\u0131l\u0131r. geli\u015ftirildi. Armat\u00fcr devresinin bir par\u00e7as\u0131 olan bir kol, diren\u00e7 kontaklar\u0131 \u00fczerinde hareket eder, \u00f6yle ki bir dizi diren\u00e7 \u00f6nce armat\u00fcr devresine konur ve ard\u0131ndan a\u015famal\u0131 olarak kald\u0131r\u0131l\u0131r.<\/span><\/p>\n
