在保证曳引机质量的前提下,与曳引机配套的电机的性能也直接关系到电梯的起制动过程的性能,问题主要表现为启动舒适感的好坏。如果电机的启动转矩大,在电梯松闸的时刻产生的倒溜就会很小。目前,在许多变频器的手册中,有严重误导用户的说法。变频器可以达到200%甚至300%以上的启动转矩,实际上都是没有实际意义的。如果一个电机的设计启动转矩 和大转矩 小,变频器再好,也不会产生大的输出转矩,而且还容易产生速度的波动,造成振荡。
根据异步电机的基本知识,电机的M-N曲线如图1(a)所示,图中A点为初启动转矩点,B点为大转矩点,C点为额定工作点。其中电机的启动转矩 与电机的转差率s有关,转差大,初始启动转矩大,要提高转差,要求转子电阻 大,转子电感小,图1(b)示出了转子电阻不同情况下的机械特性曲线。从图上还可以看出,随着转子电阻增大,大转矩 未发生变化,但是其对应的大转差 增大,在同等负载下,转差也增大。这就是进口品牌电梯采用高转差电机的原因。可是目前许多进口品牌曳引机为了降低成本,均配备国产低转差电机,转差频率一般小于2.5Hz,其启动性能大打折扣。因此在选择曳引机品牌时,其配套电机的品牌和性能的选择也同等重要。
