Integrated servo drive electronics with permanent magnet servo motors incorporate and maximize recent technological advancements while providing complete motion control solutions in a single, more compact package. Combining both drive and motor, integration improves power density with smaller and more efficient electrical components, and optimizes axis performance. Additionally, choices can come with complete network connectivity / compatibility in decentralized systems or control of simple point-to-point motion with stand-alone axes as the application for each may dictate.
Non-contact magnetic feedback is a natural selection for most integrated drive-motors. When integrating widely available magnetic encoder chips into the drive electronics, a shorter and more robust overall design is created that further eliminates costly additional encoder components. Continued advantages with magnetic encoder integration is extended environment use, both at extremely low and high temperatures. Where moisture exposure may be a problem, electronics can be conformal coated to accommodate swinging temperature ranges from one end to the other through normal operation, and no worries exist from condensation as optical devices are not in use.
In any case, integrated designs can easily accommodate many different types of feedback devices or form factors. By providing open space in the rear of the housing, a wide selection of encoders can be considered, whether in component or pre-packaged forms to fulfill the many different machine or equipment solution requirements. Small servo drives, such as ADVANCED Motion Controls’ FlexPro™ drives, might easily fit into the back of a motor without the need for custom products.
An important aspect for many OEM’s and End Users alike is the realization that this is all possible while providing a significant increase in overall system reliability and lower overall cost.
