Teknigin Bilinen Durumu Elektronik motoru, arabalarin hareket etmelerini saglayan, gelen akima göre saat yönüne veya saat yönünün tersine dönmek sureti ile hareket ederek aracin aktarim organlarini çeviren ve araci yürüten parçalardir. Elektronikli araba motorlari sensörlü ve sensörsüz ayirimindan önce içerisinde firçali (Brushed) ve firçasiz (Brushed) olmak üzere ikiye ayrilmaktadir. Firçasiz motorlar, firçalilara göre oldukça genistir. Oncelikle motor kendi içinde outrunner ve inrunner olmak üzere ikiye ayrilmaktadir. State of the Art The electronic motor is clocked according to the incoming current, which allows the cars to move. the transmission of the vehicle by moving by turning clockwise or counterclockwise. are the parts that turn the organs and move the vehicle. Electronic car engines with sensors and Before sensorless separation, to be brushed and brushless is divided into two. Brushless motors are much larger than brushed ones. Firstly The engine is divided into two as outrunner and inrunner.

Outrunner; dönme isleminin dis kasada gerçeklesmekte olup, stator bobinlerinin motor içinde sabit bir biçimde kaldigi tiptir ve bunlar Drone, Helikopter gibi rc modellerde kullanilmaktadir. lnrunner ise; diger motor türünün aksine bobinler kasada sabit sekilde kalirken, dönme hareketi miknatislari barindiran rotor da gerçeklesmektedir. Bu tip ise araba ve tekne rc modellerin de kullanilmaktadir. Firçasiz (Brushless) motorlari ayiran bir diger özellik sensör yapisidir. Bahsedilen sensör sayesinde ESC, motorun rotorunun konumunu tespit ederek daha efektif bir kontrol saglanmaktadir. Bu özellik, timing, turbo gibi özellikleri de kullanarak motordan daha yüksek verim alinmasina olanak tanimaktadir. Sensörün bir diger özelligi ise; düsük devirlerde meydana gelen motor teklemesini gidermektedir. Firçasiz motorlarin çalisma prensibi ise 3 farkli sekilde dizayn edilmistir, faz siralamasi dogru olarak baglandiysa motor saat yönünde, ters baglandi ise motor yönünün tersine dönmektedir. Outrunner; The rotation process takes place in the outer case and the stator coils of the motor It is the type in which it stays in a fixed form and these are in rc models such as Drone, Helicopter. is used. If lnrunner; Unlike other motor types, the coils are fixed in the case. while the rotation movement magnets, the rotor, which contains the magnets, also takes place. If this type It is also used in car and boat rc models. separating brushless motors Another feature is the sensor structure. Thanks to the aforementioned sensor, the ESC A more effective control is provided by detecting the position of the rotor. This feature To get higher efficiency from the engine by using features such as timing and turbo. provides the opportunity. Another feature of the sensor is; occurring at low revs Eliminates engine misfire. The working principle of brushless motors is in 3 different ways. designed, if the phase sequence is correctly connected, the motor is clockwise, reverse If it is connected, the motor rotates in the opposite direction.

Limit açili tork (LAT) motorlari özel tip firçasiz bir motordur. Tek fazli olarak çalismasi bu tip motoru digerlerinden ayiran en önemli özelliklerden biridir. Bu tip motorlar 180° açidan küçük bir açida tork üretmek için sinirlandirilmistir. LAT motorlari servovalfler, füze-yönlendirmeli radar antenleri, direkt lazer aynalari ve küçük açi ile dönmesi istenen diger sistemlerde yaygin olarak kullanilmaktadir. Yapisi genel olarak dista duran bir stator ve içte dönen bir rotordan olusmaktadir. Stator üzerinde sargilar bulunurken rotorun üzerinde sayisi degisiklik gösteren miknatislar bulunmaktadir. Basit tasarim, yüksek güvenilirlik ve kolay kontrol edilebilmesi LAT motorlarinin avantajlarinin basinda gelmektedir. LAT motorlarinin rotor yapisinda miknatis kullanilmasi durumunda karsilasilacak motordaki açi geziniminin tek tip olmasi ve sonrasinda degistirilememesi bir dezavantaj olarak ortaya çikmaktadir. Diger taraftan motorun maksimum tork degerinin degistirilebilmesinin sadece stator sargilarindaki uyarma akimiyla mümkün ve sinirli olmasi yapisinda miknatis kullanilan LAT motorlarinda karsilasilan sorunlardandir. Limit angle torque (LAT) motors are a special type of brushless motor. Single phase operation It is one of the most important features that distinguishes this type of engine from others.

Its structure is generally outward It consists of a stator and an internally rotating rotor. With windings on the stator There are magnets on the rotor, the number of which varies. simple design, High reliability and easy control are the main advantages of LAT motors. is coming. In the case of using magnets in the rotor structure of LAT motors that the angle travel in the engine to be encountered is uniform and cannot be changed afterwards turns out to be a disadvantage. On the other hand, the maximum torque of the engine It is possible to change its value only with the excitation current in the stator windings and It is limited to the LAT motors that use magnets in their structure. is one of the problems.
