Answer 1

Although feedback is not usually required,stepper motors are compatible with

feedback signals,either analog or dgital.Error is noncumulative as long as pulse-to-step integrity is maintained by the

stepper motor.A stream of pulses can be counted into stepper motors,and the stepper motor's final position will be known

within a small percentage of one step.

因在低频脉冲时发生最大动力矩，步进电机可以轻松的加载。当到达预定位置时，脉冲停止，步进电机轴停止转动，而不需要离合器或是刹车闸

。 步进电机通常在停止位置时剩余部分能量。 一旦停止，步进电机保持保持力矩所需的动量。 PM步进电机的另一个特点是切断电源时，它会

电磁滞留在停止位置。 它可以在很宽范围内转动，例如1.8到180度之间，不需要逻辑操作。步进电机拥有固有低速特性而不需减速齿轮。典型

的步进电机在500赫兹脉冲下达到150转/分钟。 步进电机的转动惯量通常很小。 同源驱动多步进电机可以维持完美的同步运转。 但是步进电机

的效率低；多数的输入能量都必须以热量耗散掉。必须准确分析负载以达到最佳的步进电机性能。同时，输入能力必须与步进电机和负载匹配。

当负载惯性异常大时可能要加阻尼来防止振动。

Answer 2

反馈通常不是需要，步进电机兼容的反馈信号，模拟或dgital.Error是noncumulative只要脉冲对完整的步骤是由步进motor.A流脉冲可以指望到步进电机，并步进电机的最后立场将被称为内一小部分的一个步骤。
由于最大动态扭矩发生率低脉冲，步进电机可以很容易地加速load.When所需的立场是达到和指挥脉冲停止，步进电机轴停止，而且也没有必要的离合器或brakes.The sepper电机通常是左活力在停止position.Once停止，步进电机抗拒动态运动最多的价值，举行torque.An额外功能的PM步进电机是，当一切权力被删除，这是magentically拘禁在过去position.A广泛的一步角度可供1.8至80 ，例如，没有逻辑manipulation.Stepper汽车拥有固有低速无齿轮reduction.A典型的步进电机驱动500聚苯硫醚轮流150 rpm.The步进电机的转子惯量通常较低。多步进电机驱动的来自同一来源的保持完美synchronization.But步进motor'sefficiency低;大部分能量必须作为热量散失。负载必须仔细分析，以实现最佳的步进电机performance.And inputsmust相应的步进电机和load.Damping时可能需要的负载惯量是非常高的，以防止振荡。
