電動機性能的評估及成本的高低,事實上在設計階段即已大部分定案,所以設計的精進是馬達工業進步的關鍵所在。
轉速高速化是目前伺服感應馬達的重要發展方向之一,其中軸承為其主要的關鍵元件。為了滿足不同的運轉條件,轉子的支撐結構要求越來越高。
本文主要探討轉子-軸承系統在運轉過程中,轉軸在各種參數下改變情形。在支撐元件中,軸承的排列方式及轉軸幾何形狀主宰了馬達的性能。由於軸承線速限制了軸承及轉軸軸頸之尺寸,因而轉軸之強度隨著轉速增加而降低。
The electrical motors performance capability and its manufacturing cost are must be taken into consideration at same time during the design stage. However, the excellent design skill is the key to the success for the electric motor companies.
One of the most important development directions of induction servomotor is the high speed rotation of the rotor shaft. Among those, the bearings are the main key components. In order to satisfy the various operating conditions, the supporting structure of a rotor are becoming very important role in the design.
One of the most important study in this thesis is to investigate the best arrangement of the rotor-bearing systems under varying parameters during the operation. For the components of the supporting system, the arrangement of the bearings and geometry of the rotor shaft become the main roles in the performance of the entire motor. Because of the size of the bearings and the rotor shaft of the motors are constrained by the rotating speed of the bearing, the strength of the shaft will be decreased as rotating speed is increased.
