Misaloli na Synchronous Motor

Struktura da Tushen Synchronous Motors

Mai girma synchronous motor yana nuna biyu masu muhimmanci: stator (babban birnin) da rotor (babban yanayi). Stator ya tattara da jirgin AC na uku, sannan rotor ya tattara da jirgen DC.

Prinsipi na Tushen:
Tushen yana nufin tsarin magana cikin stator da rotor, zan iya kawo su zuwa electromagnets. Wani wannan magnetic coupling yana da muhimmanci wajen kawo energy na shiga zuwa yanayi na mechanical.

Kawar Magana na Magnetic Field a Synchronous Motors

Jirgin AC na uku yana kawo poles na north da south a stator. Saboda jirgin yana sinusoidal, pola na wave (positive/negative) ta gama da haka har shekaru, wanda ke kawo poles na north da south a stator zuwa kimi. Wannan yana kawo magnetic field mai yanayi a stator.

Magnetic field na rotor yana kawo da jirgen DC, wanda ke fix pola da kuma kawo magnetic field mai bace - wato poles na north da south suna ci gaba.

Sakamakon yanayin na magnetic field na stator yana nufin synchronous speed, wanda ke cikakken jirgen supply da kuma sakamakon poles na motor.

Matsalolin Poles na Magnetic a Synchronous Motors

Idan poles na stator da rotor suna haɗa, yana faru force na attractive bayan su, wanda ke kawo torque mai yanayi. Torque, idan an yi amfani da shi a matsayin rotational equivalent of force, yana kawo rotor zuwa canza poles na magnetic na stator.

Bayan har shekaru, pola na pole na stator ta gama. Amma, inertia na rotor - ingantaccen ku fuskantar yanayi - yana da shi mulkin rike. Idan poles na like (north-north ko south-south) suna haɗa, yana faru force na repulsive wanda ke kawo torque mai yanayi.

Don in fahimta, za ka duba 2-pole motor: a figure na duniya, poles na stator-rotor na opposite (N-S ko S-N) suna kawo forces na attractive, kamar yadda aka nuna.

Ba a nan, poles na stator suka gama. Pole na sama na stator da rotor suna haɗa, da kuma force na repulsion yana faru bayan su.

Torque na non-unidirectional yana kawo rotor zuwa kimi da kuma saboda haka synchronous motor ba zan iya haɗa shiga ba.

Mechanism na Haɗa Shiga na Synchronous Motors

Don in haɗa shiga, rotor yana tattara da drive na external, wanda ke haɗa pola na stator da rotating magnetic field. Idan poles na stator da rotor suka haɗa, yana faru torque na unidirectional, wanda ke kawo rotor zuwa yanayi a synchronous speed na stator's field.

A lokacin da ake synchronize, motoci yana tafi a kansu sama da synchronous speed, wanda ke fix da jirgen supply da kuma sakamakon poles.
