Andkisaconstantfunctionofmaximumemf:Where:-m1andm2=numberofphasesofstatorandrotor.-Z1...
And k is a constant function of maximum emf:
Where:
- m1 and m2 = number of phases of stator and rotor.
- Z1 and Z2 = number of turns and sheets of stator and rotor.
- ξ1 and ξ2 = distribution factors for stator and rotor.
All the terms are known except the radial coordinate h which corresponds to change of sense in current along the shape profile.
With the coordinate h known, it is possible to calculate the total sheet current, by integration of the current equation between the upper a lower limits of the sheet:
The ring per-sheet current and the total currents are:
The torque is related to this total current:
VIII. CONCLUSION
With a proper choice of the materials and constructive shapes, it is possible to obtain low starting current of induction motors. This will not suppose a decrease in their torque values, and at the same time, their life is extended considerably and the maintenance is reduced.
These motors present a high starting torque related to shortcircuit current. This characteristic makes them adequate for drives in which we were asked to have a high number of starting and stops per hour. Its main inconvenience is the high cost of the tools used in the configuration of the rotor sheets, so that they should be fabricate in mass production. Nowadays there are many electrical drives of the mentioned characteristics, with increased demands.

和是一个常数函数的最大电磁场:
在哪儿。
- M 1和M 2=相数的定子和转子。
- Z 1、Z =匝数片定子和转子。
-ξ1和ξ2 =分布因素的定子和转子。
所有条款除已知的径向坐标小时对应上的变化在电流沿外形轮廓。
用坐标小时称,这是可以计算的总电流片,通过一体化的电流方程之间的上下界限的表:
每片的环电流和总电流:
扭矩是与此相关的总电流:
第八。结论
选择一个适当的材料和形状,可以获得低起动电流感应马达。这将不想减少其扭矩值,并在同一时间,他们的生活大大延长,减少维修。
这些马达提出一个高起动转矩与短路电流。这种特性使其足够的驱动器,我们被要求有大量的启动和停止每小时。其主要的不便,是高成本的工具用于配置转子片,所以他们应该在批量生产制造。现在有许多电气传动的特点,增加的需求。
