转速

Finish to design the micro CNC, I have to investigate the adaptable parameters for cutting. This paper had calculated tool's radius, spindle's rotational speed, radial depth, and feed speed by the instantaneous cutting areas of the cutting forces model. To find out the instantaneous cutting areas by mathematica which can calculate the tangential, radial and axial component of cutting forces during cutting.

设计完微型工具机后，接著探讨最佳的切削参数，本论文采用瞬时投影面积的数学模型，且推导出利用刀具半径、主轴转速、径向切深、进给速度等参数来做为瞬时切削投影面积的函数，并使用软体mathematica算出瞬间面积大小，预测出切削过程里所产生的切线切削力、径向切削力和轴向切削力。

The dimension of iPP spherulities and the degree of alloys reduced with increasing the blend temperature of rotate speeds.

而随着共混温度或共混转速的升高，iPP球晶的平均半径和结晶度逐渐减小。

This will limit the operating range of the generators. Hence, this proposal aims to develop an innovative 「dual variable configuration」 generator which can be applied to wind power system. The feature of the proposed generator is such that its windings and air gap are regulable so that the characteristics can be regulated to cope with variable rotational speed operations and different turbine designs with a control algorithm applied.

因此，本计画旨在研发一创新双重变结构之发电机，并应用於风力发电系统，其特色为利用两种发电机变结构设计-亦即「绕组切换」与「调整气隙」，结合控制法则以即时调整发电机特性，使其适用於各种叶片设计以及各种转速下之操作，并使发电机输出得以始终运作於最大功率点。
