Kollmorgen M-203-S-23

  • Product Name:​ Goldline M-203-S Medium Inertia Permanent Magnet Brushless Servo Motor
  • Product Introduction:​ Goldline M-series is the medium-inertia counterpart to the low-inertia B-series. M-203 is a frame size ~NEMA 34–42 equivalent, offering smoother low-speed operation and better match to higher-inertia loads. Used with BDS5, SERVOSTAR, or S300 drives.
