Voltage reflections and common-mode voltages-common to all inverters-can cause insulation damage to standard motors and cause harmful bearing currents.In addition,if precautions are not taken,the motor can also suffer from motor heating caused by higher harmonics generated during inverter switching.
ABB’s patented product-the output sine wave filter-configured with the ACS 1000i eliminates the aforementioned voltage reflections and common mode voltages.The motors are supplied with near perfect sinusoidal current and voltage waveforms.Not only that,the length of the motor cable can be up to 3000 meters or more without any risk of voltage reflection
电压反射和共模电压–所有逆变器存在的共性-对标准电机会造成绝缘损害,并产生有害的轴承电流。此外,如果不采取预防措施,电机还会遭受逆变器开关过程中产生的高次谐波而造成的电机发热。
ACS 1000i配置的ABB专利产品-输出正弦波滤波器-消除了上述的电压反射和共模电压。提供给电机的是近乎完美的正弦波电流和电压波形。不仅如此,电机电缆的长度可达3000米或更长,而不存在任何电压反射的风险
