What Affects the Vibration Level of a Miniature Vibration Motor?

Me Ke Shafar Matsayin Girgizar Ƙaramin Motar Girgiza?

I. Ra'ayin Matakin Girgiza

Matakin girgiza na ƙaramin injin girgiza mai gogewa yana nuna ƙarfin motar yana girgiza. Ana auna shi da sigogi kamar hanzari da ƙaura. Saurin hanzari yana gaya mana yadda saurin girgiza ke canzawa da kuma nisan da sassan motar ke motsawa daga matsayinsu na farawa. Tare, waɗannan suna taimaka mana mu san ƙarfin girgiza.

II. Tsarin Lissafi na Ka'ida don Matsayin Girgiza

a = m(2πn)²r / M

A. Bayanin Sigogi

- a: Matakan girgiza (hanzari)

- Abubuwan da suka dace: m (matsayin centroid na mota), r (radius na centroid), n (gudun)

- Ma'auni mara kyau: M (nauyin farantin tushe, gami da nauyin motar)

B. Bayanin Ka'ida

Da sauran abubuwa iri ɗaya, ana jin ƙarar girgiza idan na'urar girgizar motar ta yi nauyi, injin ya fi girma, ƙarfinsa da saurinsa sun fi girma, ko kuma dukkan samfurin ya yi sauƙi.

C. Amfani da Aiki

A aikace, muna amfani da "G" don nuna yawan hanzari. An kwatanta shi da saurin nauyi (g = 9.8 m/s²). Misali, idan ƙimar PEAK na mai gwada girgiza shine 11.42, yawan hanzari shine 11.42 ÷9.8≈1.16G.

III. Manyan Abubuwan da ke Shafar Ma'aunin Matakin Girgiza

1. Tasirin Nauyin Kayan Aiki

Nauyin kayan aiki yana shafar ma'aunin. Babban kayan aiki yana shan kuzarin girgiza, yana sa girgizar da aka auna ta yi kama da ƙasa da yadda take. Ƙaramin kayan aiki ba zai iya riƙe injin da kyau ba, wanda ke haifar da ma'auni marasa daidaituwa.

2. Tasirin Hanyar Shigar da Firikwensin

Ga waɗannan injinan da ke da ma'aunin girgiza, matsayin firikwensin yana da mahimmanci. Sanya injin a tsakiyar na'urar da firikwensin a gefe yana ba da mafi girman karantawa. Da zarar firikwensin ya yi nisa da injin, to, girgizar da aka auna ta yi rauni.

IV. Shawarwari don Shigar da Mota Yayin Amfani da Abokin Ciniki

1. Samun Mafi girman Fitar Girgiza

Domin samun mafi yawan girgiza, shigar da injin a gefen samfurin, kamar sama ko ƙasa. Wannan saitin "eccentric" yana ƙara ƙarfin girgizar.

2. Rage Ƙarfin Girgizawa

Don rage girgizar, shigar da injin a tsakiyar samfurin. Ko kuma, yi amfani da ikon sarrafa PWM ko ƙara resistor mai raba wutar lantarki don rage ƙarfin lantarki da saurin motar.
