Our inductive filter cards have been designed to complement ADVANCED MOTION CONTROLS servo amplifiers. These filters contain two inductors for single phase loads and three inductors for three phase loads. Inductive filter cards have two typical applications: 1. To increase the inductance to meet the minimum load inductance requirement of Advanced Motion Controls amplifiers. Some motors have inductances that are less than the minimum load inductance requirement for the amplifier. For example "basket-wound" and "pancake" motors do not have a conventional iron core rotor so the winding inductance is usually less than 25
