High torque servo motor drivers improve performance

ABB has enhanced its ranges of servomotor drives for ethernet-based motion control systems with variants which can substantially increase the speed of machinery and automation systems while also reducing bill-of-materials costs. By redesigning the drives’ power stage, the latest iteration of the MicroFlex e100 and e150 servo motor drives can now deliver peak current levels that are three times the continuous rated current  providing the torque to substantially increase the speed of moves and machine cycle times. The new design increases the drives’ level of overcurrent capability from 200 to 300%. This can be particularly relevant for system builders employing new generations of high performance servo motors with neodymium magnets, as these tend to offer a peak current capability that is at least three times the continuous rated current level. As many common types of automation and machinery have a lot of repetitive movements coupled with dwell periods, this can have a dramatic impact on overall cycle time and throughput. These types of operational modes can be found in many applications such as feeding materials, parts handling, assembly, filling, packaging, labelling, sampling and robotics.
