Takaitaccen hanyar torque

Akwai na iya kalkulasu torque a motorin induction da tasiri goma sha daya ta hanyar current na rotor, magnetic flux da power factor.

Current na rotor

Current na rotor yana da muhimmanci wajen samun torque kuma ana iya kasance saboda electromotive force da impedance na rotor.

Starting torque

Starting torque shine torque da take samu a lokacin da motorin induction ya faru. Ana sani cewa a baya fadada rotor N tana ɗauke.

Saboda haka, idan an sama s=1 a hanyar torque na motorin induction da tasiri goma sha daya, za a iya samun hanyar starting torque ta da saƙo.

Starting torque tana da sunan rest torque kuma.

Matsayin maximum torque

Idan slip ya dace da tsari da resistance na rotor zuwa reactance na rotor, zai samu maximum torque, wanda yake nuna muhimmancin takamfa na rotor.

Slip da speed

Values na slip suka fi muhimmanci wajen neman speed da efficiency na motor, kuma values na slip masu ɗauke suna ba da efficiency masu ɗaya.

Hanyar torque shine

Idan slip s = R, torque zai ɗauke da ɗaya

Idan an sama slip daga hanyar, muna samu maximum torque,

Saboda hakan don samun starting torque masu ɗaya, ya kamata a zama additional resistance zuwa circuit na rotor a lokacin da faru kuma a zama gradual cut-off idan motor ya haɗa shiga.

Kammalawa

Daga hanyar da aka bayar, muna iya kammala cewa:

• Maximum torque ana dogara da square da induced electromotive force na rotor a lokacin da ita ɗauke.

• Maximum torque ana dogara da inverse da reactance na rotor.

• Yana da kyau a sani cewa maximum torque ba ya yi amfani da resistance na rotor.

• Slip inda maximum torque yake faru ana dogara da resistance na rotor R2. Saboda haka, tare da vary da resistance na rotor, muna iya samun maximum torque da any desired slip.
