失步原因及解决方法 1．转子的加速度慢子步进电动机的旋转磁场 转子的力n速度慢于步进电动机的旋转磁场，即低于换相速度时，步进电动机会产生失步。这是因为输入电动机的电能不足，在步进电动机中产生的同步力矩无法使转子速度跟随定子磁场的旋转速度，从而引起失步。由于步进电动机的动态输出转矩随着连续运行频率的上升而降低，因而，凡是比该频率高的工作频率都将产生丢步。这种失步说明步进电动机的转矩不足，拖动能力不够。解决方法：①使步进电动机本身产生的电磁转矩增大。为此可在额定电流范围内适当加大驱动电流；在高频范围转矩不足时，可适当提高驱动电路的驱动电压；改用转矩大的步进电动机等。②使步进电动机需要克服的转矩减小。为此可适当降低电动机运行频率，以便提高电动机的输出转矩；设定较长的加速时间，以便转子获得足够的能 量。

铝合金门窗，是指采用铝合金挤压型材为框、梃、扇料制作的门窗称为铝合金门窗，简称铝门窗。铝合金门窗包括以铝合金作受力杆件(承受并传递自重和荷载的杆件)基材的和木材、塑料复合的门窗，简称铝木复合门窗、铝塑复合门窗。铝合金门窗的保养介绍使用铝合金门窗，推拉动作要轻，发现有困难不要硬拉硬推，应先排除故障。积灰、变形是铝合金推拉困难的主要原因，要保持门框清洁，特别是推拉槽的清洁。可用吸尘器吸去槽内和门封毛条的积灰。
