DC motor: da na'urar, mai aiki aikace-aikace

The aikin tattauna a wannan labarin, da naúrar ya dogara ne a kan sabon abu daga electromagnetic shigar da. Wannan shi ne ainihin manufa na aiki na mota DC. Sananne ne cewa halin yanzu-dauke da shugaba mikawa kanta sanya a cikin wani Magnetic filin zone, yana da wani sakamako ƙarfi, wanda za a iya ƙaddara daidai da hagu-hannun mulkin: F = B * I * L, inda -electric halin yanzu ina, B - shigar da filin. L - da dabara tsawon. Tsallaka layin da Magnetic karfi, da shugaba yakan mallaki wani electromotive karfi, wanda a halin yanzu dangane da kwarara ne directed da shi, kuma aka kira a baya ko counter. A motor sabobin tuba cikin DC ikon zuwa wani inji nau'i na makamashi, amma kuma partially ciyar da ita a kan dumama.

A surface na inji taro na'urar za a iya gani kamar haka: da DC motor tsarin ne in mun gwada sauki, shi ne wakilta inductor da armature, wanda aka ware da wani iska rata.

Inductor halitta da keken Magnetic filin daga cikin na'ura da kuma, bi da bi, kunshi wani firam, da iyakacin duniya (main kuma ƙarin). Saka a kan frame sanduna, da substrate kanta ne da hannu a cikin shigarwa na Magnetic kewaye. Babban filin Tuddan sandunan zasu samar da wani Magnetic filin, da kuma karin - nada don inganta connection.

Motor DC sanye take da anga daga raba zanen gado, waya da kuma nada tafki (Fitted a kan shaft Silinda na jan karfe faranti). Material kau ne da za'ayi amfani da yanzu goga. Suna gyarawa da kuma aka gudanar a wani wuri, wanda ya samar da ake buƙata karfi na matsin lamba a kan tara surface.

Lokacin aiki na DC goga motor motsa a kan surface na zagawa da tafki a irin wannan hanyar da aka kullum motsi daga daya farantin zuwa wani. Saboda haka canja layi daya sassan na nada da kuma armature halin yanzu an canza. Tsari, kazalika da mamaki hade da shi, an kira sharuddan sauyawa. EMF sa ƙarin halin yanzu, wanda yana da wani m rarraba ikon yawa a kan surface na goge. Wannan ne babban dalilin da ya haifar da da tara (a cikin tsanani da wannan sabon abu ne kiyasta sharuddan sauyawa kuma ingancin grading tsare ta iko).

DC motor iya jurewa zumudi - samar da shi a halin maganaɗisu filin da ake bukata a cikin na'urar. Sun kasu kashi hudu kungiyoyin (tuki Hanyar):

• Independent wanda Tuddan powered daga wani waje DC Madogararsa.
• Layi daya - Tuddan a layi daya don bayar da armature nada.
• M - alaka a jerin.
• Gauraye (tare da serial da layi daya zumudi coils).

A farko farawa ƙarfin lantarki da kuma armature da ake gyarawa a shi ne sifili. Resistance ne kananan, don haka lokacin da na fara halin yanzu zai iya zama 10-20 fiye da sau da rated. Don tabbatar da wani m farko-up ne amfani stepwise resistor wanda juriya darajar yiwu an zabe ta Starter motor halin yanzu.
