Teknigin bilinen durumu Sincap kafesli asenkron motorlar temel olarak stator, rotor ve gövdeden olusmaktadirlar. State of the art Squirrel cage induction motors basically consist of stator, rotor and body.
Stator sargilarin bulundugu ve manyetik alanin olusturuldugu, üzerinde stator oluklari açilmis bir nüve barindirrnaktadir. Rotor ise yine üzerinde oluklar açilmis bir nüve ve bu oluklara yerlestirilmis rotor çubuklarindan olusmaktadir. Gövde ise alüminyum malzemeden veya pik döküm malzemeden yapilmis hem statoru hem de rotoru çevreleyen parçadir. The stator windings are located and the magnetic field is created, the stator grooves are opened on it. contains a core. The rotor, on the other hand, is a core with grooves on it and these grooves It consists of placed rotor bars. The body is made of aluminum material or cast iron. It is the part that surrounds both the stator and the rotor made of casting material.
Sincap kafesli asenkron motorlar çalistirildiklarinda stator ve rotor nüvesinde histeresiz ve fukolt kayiplari meydana gelmektedir. Bu kayiplar motor üzerinde isi seklinde kendini göstermektedir. Ayrica stator ve rotor arasinda bulunan hava araligi kisminda, manyetik akilarin hava araligi kisminda dolasmasiyla salinim kayiplari ve ilave yük kayiplari meydana gelmektedir. Bu kayiplar motor performansini olumsuz yönde etkilemektedirler. Ayrica rotor tepkisi de faydali akiyi azaltarak motor performansini olumsuz yönde etkilemektedir. Üretici firmalar bu kayiplari azalmak için stator ve rotor nüvesinde geçirgenligi yüksek, daha kaliteli, kayip güç degerleri daha az olan nüve malzemeleri kullanmaktadir. Fakat yine de bu kayiplarin meydana geldigi görülmektedir. When squirrel-cage asynchronous motors are started, hysteresis and hysteresis in the stator and rotor core fukolt losses occur. These losses manifest themselves in the form of heat on the engine. shows. Also, in the air gap between the stator and the rotor, the magnetic Oscillation losses and additional load losses occur as the fluxes circulate in the air gap part. is coming. These losses negatively affect engine performance. Also rotor response also affects the engine performance negatively by reducing the useful flux. In order to reduce these losses, manufacturing companies have high permeability in the stator and rotor core, It uses high quality core materials with less power loss. But still this losses appear to have occurred.
Bulusun çözümü amaçladigi teknik problemler Önerilen nüve tasarimi ile sincap kafesli asenkron motorlarda rotor tepkisi ile manyetik aki azalmasini ve beraberinde motor performansini bozan kaçak aki, kayip artisi, verim düsüsü gibi önemli etkileri daha yüksek kaliteli sac kullanmadan rotor tepkisinin azaltilmasi ve çalisma performansin artirilmasi amaçlanmistir. Bulusun amacina ulasmak için gerçeklestirilen yarikli nüve tasarimi asagidaki sekilde gösterilmektedir. Technical problems that the invention aims to solve With the proposed core design, rotor response and magnetic flux in squirrel cage induction motors leakage flux, increase in loss, decrease in efficiency, which impairs the reduction of the engine performance and reducing rotor response without using higher quality sheet metal, and It is aimed to increase the working performance. To reach the purpose of the invention The slotted core design realized is shown in the figure below.
