伺服电动机有两项技术值得注意，一是高密度电机，采用一种叫“大电机”的设计思想。例如六九槽电机，定子由九个独立的构成，在每个上绕制集中线圈，然后再将九个拼装起来，形成九个槽的电机铁芯。由于每个是独立绕制和整形，所以即使采用自动机绕，也能保持槽满率高达90%。这类电机制造工艺好，空间利用和体积都达到了小化，故称为高密度电机。从运行原理上讲，这类电机不属于旋转磁场电机，它在三相脉振磁场下工作，因此，它的适用性、设计方法和运行方式都有特殊性，所以这类电机不适合方波电流驱动。
另一类是嵌入式磁钢速率伺服电动机，它可利用凸效应引起的交、直轴电感随位置变化的特点，构成真正意义上的无位置传感器速率伺服电动驱动系统。
传感器
除了各类光电编码器以外，磁编码器值得关注。磁编码器的体积和重量都比光电编码器小几十倍，温度范围更宽，几乎不怕冲击和振动。其工作原理非常简单，它的定子是一颗内嵌霍尔磁敏元件和DSP的芯片，体积可以小到MSOP-24封装，它的转子是一颗两磁钢。它的分辨率10—12位，精度8—10位。这种磁编码器已有供应。
作为空间应用，为了满足-35℃—80℃环境要求，几乎难以采用传统的光电编码器，为此我们自行研制了磁编码器，分辨率16位，精度12位。磁编码器信号处理电路共存于驱动控制电路（FPGA）中，形成传感器与驱动控制电路一体化。
电流传感器是伺服控制必不可少的，小功率系统可以采用电阻采样，一般可采用 [1] 霍尔电流传感器。两种方法都要将模拟信号转换成数字信号，然后参于数字伺服控制。上述A/D转换的输出形式通常是串行数字脉冲或脉宽调制信号。
