1、步进电机发热随速度变化的情况：

采用恒流驱动技术时，步进电机在静态和低速下，电流会维持恒定，以保持恒力矩输出。速度高到一定程度，电机内部反电势升高，电流将逐步下降，力矩也会下降。因此，因铜损带来的发热情况就与速度相关了。静态和低速时一般发热高，高速时发热低。但是铁损(虽然占的比例较小)变化的情况却不尽然，而电机整个的发热是二者之和，所以上述只是一般情况。

2、发热带来的影响：

电机发热虽然一般不会影响电机的寿命，对大多数客户没必要理会。但是严重时会带来一些负面影响。如电机内部各部分热膨胀系数不同导致结构应力的变化和内部气隙的微小变化，会影响电机的动态响应，高速会容易失步。又如有些场合不允许电机的过度发热，如器械和高精度的测试设备等。因此对电机的发热应当进行必要的控制。

选泵时，要求工作点所对应的流量和压头既能满足管路系统的要求，又正好是离心泵所提供的，即Q=Qe，H=He。卫生级离心泵一流量调节卫生级离心泵一改变阀门的开度改变离心泵出口管线上的阀门开关，其实质是改变管路特性曲线。如下图所示，当阀门关小时，管路的局部阻力加大，管路特性曲线变陡，工作点由M移至M1，流量由QM减小到QM1。当阀门开大时，管路阻力减小，管路特性曲线变得平坦一些，工作点移至M2，流量加大到QM2。
