Sin\u00fczoidal Olmayan \u00c7\u0131k\u0131\u015f ve Motor Performans\u0131 \u00dczerindeki Etkileri<\/h3>\n<\/div>\n<\/div>\n\n\n\n

Bir VFD motor h\u0131z\u0131n\u0131 d\u00fczenledi\u011finde, \u00e7\u0131k\u0131\u015f voltaj\u0131 dalga formu m\u00fckemmel bir sin\u00fcs dalgas\u0131 de\u011fildir. Bunun yerine, tipik olarak kademeli veya darbe geni\u015fli\u011fi mod\u00fclasyonlu (PWM) bir sinyale benzer ve motor performans\u0131n\u0131 a\u015fa\u011f\u0131daki \u015fekillerde etkileyen harmonik bile\u015fenler ortaya \u00e7\u0131kar:<\/p>\n\n\n\n

1. Artan Bak\u0131r Kay\u0131plar\u0131<\/h4>\n\n\n\n

Stator Bak\u0131r Kay\u0131plar\u0131:<\/strong>
Stator sarg\u0131lar\u0131nda ind\u00fcklenen harmonik ak\u0131mlar bak\u0131r kay\u0131plar\u0131n\u0131 (I\u00b2R kay\u0131plar\u0131) art\u0131r\u0131r. Bu durum \u00f6zellikle harmonikler girdap ak\u0131mlar\u0131na ve manyetik doygunlu\u011fa neden olarak daha y\u00fcksek uyarma ak\u0131m\u0131 gereksinimlerine ve dolay\u0131s\u0131yla motor taraf\u0131ndan \u00e7ekilen toplam ak\u0131mda bir art\u0131\u015fa yol a\u00e7t\u0131\u011f\u0131nda fark edilir.<\/p>\n\n\n\n

Rotor Bak\u0131r Kay\u0131plar\u0131:<\/strong>
Rotor \u00e7ubuklar\u0131, \u00f6zellikle derin yar\u0131kl\u0131 sincap kafesli rotorlarda, harmonik frekanslarda deri etkisi nedeniyle \u00f6nemli \u00f6l\u00e7\u00fcde daha y\u00fcksek kay\u0131plar ya\u015far. \u00d6rne\u011fin, 50Hz temel frekansta, be\u015finci ve yedinci harmonikler s\u0131ras\u0131yla 300Hz ve 600Hz'de rotor ak\u0131mlar\u0131 olu\u015fturur. Bu kadar y\u00fcksek frekanslarda, rotorun AC direnci dramatik bir \u015fekilde artar - bazen DC direncinin 3,7 kat\u0131na kadar - daha fazla enerji kayb\u0131na ve \u0131s\u0131 olu\u015fumuna neden olur.<\/p>\n\n\n\n

2. Artan Demir Kay\u0131plar\u0131<\/h4>\n\n\n\n

Harmoniklerin varl\u0131\u011f\u0131, zamanla de\u011fi\u015fen manyetik alanlar ek girdap ak\u0131mlar\u0131 ve histerezis kay\u0131plar\u0131 olu\u015fturdu\u011fundan, motorda y\u00fcksek demir kay\u0131plar\u0131na (n\u00fcve kay\u0131plar\u0131) da yol a\u00e7ar. Birincil manyetik ak\u0131 temel dalga bi\u00e7imine ba\u011fl\u0131 kal\u0131rken, harmonik ak\u0131lar \u0131s\u0131nman\u0131n artmas\u0131na ve motor verimlili\u011finin azalmas\u0131na katk\u0131da bulunur.<\/p>\n\n\n\n

Bir VFD'den gelen tipik bir 6 ad\u0131ml\u0131 dalga bi\u00e7iminde bile, motor hava aral\u0131\u011f\u0131ndaki tepe manyetik ak\u0131 saf sin\u00fcs dalgas\u0131ndan 10% daha y\u00fcksek olabilir, ancak demir kayb\u0131ndaki ger\u00e7ek art\u0131\u015f nispeten m\u00fctevaz\u0131d\u0131r.<\/p>\n\n\n\n

3. Ek Ka\u00e7ak Kay\u0131plar<\/h4>\n\n\n\n

U\u00e7 Sarg\u0131 Ka\u00e7a\u011f\u0131 ve Girdap Ak\u0131mlar\u0131:<\/strong>
Y\u00fcksek frekansl\u0131 harmonikler ayr\u0131ca stator u\u00e7 sarg\u0131lar\u0131 ve motor u\u00e7 kapaklar\u0131ndaki ek girdap ak\u0131mlar\u0131 nedeniyle ka\u00e7ak kay\u0131plar\u0131 da art\u0131r\u0131r. Bu kay\u0131plar kapal\u0131 yuval\u0131 veya e\u011fri yuval\u0131 tasar\u0131mlara sahip motorlarda daha belirgindir.<\/p>\n\n\n\n

E\u011fri Yuva Ka\u00e7ak Ak\u0131s\u0131:<\/strong>
Stator ve rotor manyetik alanlar\u0131 aras\u0131ndaki faz a\u00e7\u0131s\u0131 harmonik etki alt\u0131nda de\u011fi\u015fti\u011finden, \u00e7arp\u0131k yuval\u0131 ka\u00e7ak ak\u0131, \u00f6zellikle motor \u00e7ekirde\u011finin u\u00e7 sarg\u0131lar\u0131 ve di\u015fleri yak\u0131n\u0131nda b\u00f6lgesel \u0131s\u0131nmaya yol a\u00e7ar.<\/p>\n\n\n\n
