(4)在重物开始升降或停止时，要求制动器和电动机的动作之间，必须紧密配合。由于制动器从抱紧到松开，以及从松开到抱紧的动作过程需要一定的时间(约6s)，

而电动机转矩的产生或消失是在通电或断电瞬间就立刻反映的。因此，两者在动作的配合上极易出现问题。如电动机已经通电，而制动器尚未松开，将导致电动机的严重过载；反之，如电动机已经断电，而制动器尚未抱紧，则重物必将下滑，即出现溜钩现象。4　起重机械变频调速采取的措施 
4.1　选择合适的变频器容量
在起重机械中，因为升、降速时的电流较大，应求出对应于 大起动转矩和升降速转矩的电动机电流。
通常，起重机械用变频器容量按以下步骤求出：
(1)恒定负荷上升时的电动机容量PMN
（kW） （5）
式中，GN——额定重量(kg)，具体计算时，应考虑须有125％的过载能力；
v——额定线速度(m/min)：
η——机械效率。
(2)变频器容量
变频器的额定电流可由下式求出：
变频器额定电流>电动机额定电流× (6)
式中，k1——所需 大转矩÷电动机额定转矩；
k2——1.5(变频器的过载能力)；
k3——1.1(余量)。
4.2　溜钩的预防措施 
起升机构中，由于重物具有重力的原因，如没有专门的制动装置，重物在空中是停不住的。为此，电动机轴上必须加装制动器，常用的有电磁铁制动器和液压电磁制动器等。多数制动器都采用常闭式的，即：线圈断电时制动器依靠弹簧的力量将轴抱住，线圈通电时松开。 
为了有效地防止溜钩，某些新型变频器设置了一些独特的制动功能，如：
(1)零速全转矩功能变频器可以在速度为0的状态下，电动机的转矩也能达到额定转矩的150％。这就保证了吊钩由升、降速状态降为零速时，电动机能够使重物在空中暂时停住，直到电磁制动器将轴抱住为止，从而防止了溜钩。
