Dalilai na Torque Mai Gajarta

• Mai Gajarta da Karamin Kirki: A cikin lokacin da aka taka shi, motorin induction yana kara kirki mai gajarta, yawancin da ke 5 zuwa 7 karamin kirkin da aka bayar. Wannan kirki mai gajarta yana zama zafiya masu flux mai magana, wanda yake haɗa da torque mai gajarta.

• Factor Mai Gajarta Da Yake: A cikin lokacin da aka taka shi, motorin yana yi aiki a factor mai gajarta da yake, ma'ana haka yawancin da ke kara kirki ana iya amfani da ita don haɗa kan magnetic field ba tare da rashin yaɗa torque mai kyau.

• Tushen Masu Sauran: Don in ba da torque mai kyau a cikin lokacin da aka taka shi, motorin induction suna faɗa da tushen da suke da torque mai gajarta a wasu lamarin kadan.

Hanyoyin Da Zan Iya Amfani Da Su Don Tabbatar Torque Mai Gajarta

Kawo Voltage Mai Gajarta

Prinsip: Kawo voltage da aka baka da motorin don kawo kirki da torque mai gajarta.

Hanyoyin

• Star-Delta Starting: A cikin lokacin da aka taka shi, motorin yana baka a star configuration, sannan ya dogara zuwa delta configuration idan an samu waɗannan tashe.

• Auto-transformer Starting: Amfani da auto-transformer don kawo starting voltage.

• Series Resistor or Reactor Starting: Baka resistors ko reactors a series da motorin a cikin lokacin da aka taka shi don kawo starting voltage.

Amfani Da Soft Starter

• Prinsip: Fadada baka voltage da aka baka da motorin don tsara lokacin da aka taka shi, kawo kirki da torque mai gajarta.

• Hanyoyin: Amfani da soft starter don kontrollo starting voltage, fadada baka shi zuwa rated value.

Amfani Da Variable Frequency Drive (VFD)

• Prinsip: Kontrollo speed da torque na motorin tare da vary frequency da voltage na power supply.

• Hanyoyin: Amfani da VFD don taka motorin a low frequency da voltage, fadada baka duka zuwa rated values.

DC Injection Braking

• Prinsip: Baka DC current a stator windings kafin ko a lokacin da aka taka shi don haɗa magnetic field wanda yake kawo torque mai gajarta.

• Hanyoyin: Kontrollo magnitude da duration na DC current don regulate starting torque.

Amfani Da Dual-Speed ko Multi-Speed Motors

• Prinsip: Shafi connection na winding na motorin don samun speeds da torque characteristics daban-daban.

• Hanyoyin: Faɗa multi-speed motors wanda suke yi aiki a low speed a cikin lokacin da aka taka shi, sannan dogara zuwa high speed baƙin taka shi.

Sakamakon Tushen Motorin

• Prinsip: Sauke tushen motorin don kawo magnetic flux density da kirki mai gajarta a cikin lokacin da aka taka shi.

• Hanyoyin: Zaɓe winding designs da materials daidai, kuma sakamako magnetic circuit structure don kawo magnetic saturation a cikin lokacin da aka taka shi.

Gajarta

Torque mai gajarta na motorin induction yana da shirin da shi a cikin tushen da suke da operating principles. Amma, akwai hanyoyi daban-daban da za a iya amfani da su don kawo torque mai gajarta da kuma kawo impact na power grid da mechanical systems. Hanyoyin mafi yawan amfani sun hada da kawo voltage mai gajarta, amfani da soft starters, amfani da variable frequency drives (VFDs), DC injection braking, amfani da dual-speed ko multi-speed motors, da kuma sakamakon tushen motorin. Zan iya zaɓe hanyoyin da ya dace a cikin specific application requirements da system conditions.
