力矩电机直驱转台的精度卡在转子、轴承、编码器三者的同轴：转子跳动落到转台边缘即角秒误差，编码器偏心把机械误差写进反馈，误差沿角度累加。

直线电机在半导体设备上的卡点是磁轨多段拼接：接缝台阶与贴装高度公差决定气隙均匀度，法向吸力放大装配风险，长行程把三段误差累加放大。

三相异步电机的气隙卡在定子压装：机座止口与铁芯外圆同轴度先定基准，铁芯叠压与烘烤变形再吃掉一段余量，四条基准串联后散差落在最小气隙一侧。

轴向磁通电机体积小、功率密度高，但定转子合装受强磁吸力制约，气隙均匀度与磁钢定位决定批量一致性。量产拼的不是设计，是装配过程能否被固定住。

轴向磁通电机磁力线平行于转轴，定子被双层转子夹住，同功率下体积与重量约减半。它的量产难点集中在磁钢耐温与定转子合装，制造一致性直接决定良率与节拍。

A multi-pole architecture brings a high-frequency fundamental; at 10,000 rpm the fundamental frequency can reach several kHz. Traditional IGBTs suffer soaring switching losses and severe heating — it is the MHz-class switching capability of SiC MOSFETs that truly matches high-frequency multi-pole axial flux motors.
