The MDrive® product line, from IMS Intelligent Motion Systems, Inc., with its integrated motor+driver technology, provides an optional internal encoder for reliable position monitoring with differential or single ended outputs.
The internal encoder is less prone to electrical noise interference, is available with a choice of line counts, and does not increase the MDrive product size. Offered as an option for MDrive 14, 17 and 23 Microstepping versions with step and direction input, the optional internal magnetic encoder provides position monitoring that is less prone to interference in harsh environments. Nine line counts are available from 100 to as high as 1000 for applications demanding finer resolutions. All resolutions include an index mark.
