定子内径与转子外径之间的特定比例可使它们的磁通量大化。但是，使转子太大会增加转子惯性，并会使电机对速度变化的响应变差。较大的转子直径也会导致定子绕组的空间减少，从而减少产生的磁通量。进行了重复测试以确定佳比例。

· 定子叠片

为了大限度地减少磁通量损耗，我们重点设计了定子叠片上小齿的凸极宽度、背轭宽度和表面积。齿形也比过去的设计更方，这大限度地减少了定子齿和转子齿之间的磁通量损失。

· 转子叠片

转子是通过在永磁体的每一侧固定许多薄齿硅钢片而制成的。研究证明，存在可使扭矩大化的理想叠片数量。通过检查磁化特性的峰值电压和饱和电压，我们能够同时增加扭矩并降低扭矩波动引起的振动。

提高刚性

采用更大的轴承以提高刚性并增加径向载荷。轴的底部直径已增加。这导致径向载荷比过去的设计大 1.4 到 1.5 倍。还在电机输出侧的轴承组件中添加了粘合剂，从而减少了轴承箱组件上的间隙，增加了增加转子长度的空间，并减少了振动。我们还改进了定子叠片的紧固方法，以提高转子和定子铁芯的刚性，这也有助于进一步降低电机产生的振动。
