电机的高效率需要高转速，用齿轮泵、叶片泵、柱塞泵，适配的电机和减速器效率又差了很多。我觉得最现实的方法是2-4MPa，这样一级离心泵就足够了。计算过程大概是：压力-转速-流量-效率-扭矩-电机功率

步进电机，我拆过几个硬盘电机，都是四线三相的，也做过驱动电路，我用单片机+uln2003就可以驱动了，电流不大，基本原理就是找到公共地端，大致就是分别按照正极1,2,3的顺序连接正转，321顺序反转，调节停顿时间可以调节速度

圈神和我们做的这种电机属于脉冲式的，我做的那种没铁芯，和普通励磁电机完全不一样，转子不克服铁芯吸力，半周加速，半周无加速，反馈线圈的由于是电压控制电流小，对转子无明显减速。
