abb电机的额外转速挑选，要根据拖动花费机械的央求及传动设备的配比状况来思索。
ABB电机每分钟的转数平日有3000、1500、1000、750及600等多种，异步电主见额外转速由于存在转差率，一般要比上述转速低2％～5%。
从ABB电机制作视点讲，失常功率的电机若额外转速越高，其电磁转矩外形尺寸就愈小，本钱就愈低且分量亦轻，而且高速电机的功率因数及效能比低速电机都高。若能挑选转速愈高的佳木斯电机，则经济性愈好，但若由此而惹起电主见与被拖主见械间的转速相差过大时，所需装设加快设备的传动级数就越多，这就会加大配备本钱及传动的能量损耗。故要经由分析对比择优选定。
咱们平日运用的ABB电机大多数是选用4极1500r/min的电机，由于这种额外转速的西门子电机习气计划广，而且其功率因数和使命效能也较高。 的额外转速挑选，要根据拖动花费机械的央求及传动设备的配比状况来考虑。
