Wani Deep Bar Double Cage Induction Motor?

Zai da shi Deep Bar Double Cage Induction Motor?

Ma'ana da Deep bar double cage induction motor

Motoda deep-bar double-cage induction suna motoci da take amfani da rotor biyu don taimaka hanyar kawo da karfi da na yin da na yi.

Siffarwar rotor biyu

A cikin rotor biyu, rod deep ya zama biyar.

Tsakiyar gaba ta da tsari mai yawa da zarafin mafi yawa, an kofara ita a farkon baya. Wannan ya haɗa da darajar da yawa da inductance mafi yawa. Zarafin mafi yawa ta cikin tsakiya gaba ta haɗa da karfin kawo da mafi yawa tare da maida aiki. Tsakiyar gida ta da rod da tsari mai yawan yawa da zarafin mafi yawa. Rododin wa suka zama a iron, wanda ya haɗa da darajar da yawa da inductance mafi yawa. Zarafin mafi yawa da inductive reactance ratio mafi yawa ta haɗa da tsakiya gida ta zama daidai a lokacin da ake amfani a cikin aiki.

Addinin aiki

A lokacin da ya fi shiga, rododin gida da gaba suka shiga voltage da current a matsayin fadin sama. Yanzu ana iya cewa inductive reactance (XL= 2πfL) ya samun mafi yawa a cikin rod deep ko gida saboda skin effect da ke faruwa (voltage da current). Saboda haka, current ta gane irin ita a cikin rod gaban rotor.

Rotor gaba ta haɗa da zarafin mafi yawa, amma inductive resistance mafi yawa. Zarafin da ta dace a cikin rotor ya kasance mafi yawa da zarafin rotor da rod biyu. Idan zarafin rotor ya kasance mafi yawa, karfin kawo da ya samun mafi yawa a lokacin da ake shiga. A lokacin da rotor speed na deep-bar double-cage induction motor ya zama mafi yawa, frequency da induced electromotive force da current suka rage mafi yawa. Saboda haka, inductive reactance ya rage mafi yawa a cikin rod gida ko deep rod, da kuma current ya zama da inductive reactance mafi yawa da zarafin mafi yawa. Ba za a buƙata karfi mafi yawa ba saboda rotor ya samu speed da yake da aiki.

Muhimmin karfi da speed

Idan, R2 da X2 su ne rotor resistance da inductive reactance a lokacin da ake shiga, E2 shine rotor induced electromotive force da

Ns shine RPS speed don synchronize stator flux, da S shine slip ta rotor speed. Diagram na speed-torque na gaba ta nuna cewa a lokacin da ya fi shiga, idan zarafin da ta dace mafi yawa, karfin kawo da za su mafi yawa, da kuma idan slip value mafi yawa, karfin kawo da za su mafi yawa.

Tambayar da motor ta single cage da motor ta double cage

• Rotor biyu ta da current da ya faru mafi yawa da karfin kawo da mafi yawa. Saboda haka, ya zama daidai don direct online startup.

• Saboda effective rotor resistance mafi yawa na double-cage motor, rotor ta yan sake mafi yawa a lokacin da ake shiga musamman da single-cage motor.

• Zarafin mafi yawa ta cikin tsakiya gaba ta haɗa da zarafin double cage motor. Amma, full load copper loss ta rage mafi yawa da efficiency ta rage mafi yawa.

• Pull out torque na double cage motor ta mafi yawa da single cage motor.

• Gaskiya na double-cage motor ta mafi yawa da single-cage motor ta hanyar grade mafi yawa da 20-30%.
