Kollmorgen 57M-4.000-M-AG-6R
Product Name: Kollmorgen 57M Series Hybrid Stepping Motor — 57 mm frame, 4.000″ stack length, AG winding, 6-lead or 8-lead configuration
Product Introduction:
Industrial hybrid stepper (2-phase bipolar) from Kollmorgen’s stepping motor line. “57M” = 57 mm square flange (NEMA 23 equivalent). “4.000” = 4.0 inch (101.6 mm) stack length indicating medium-high torque for its frame.

General Notes & Warnings
-
All servo motors must NOT be connected directly to AC mains; they require a properly matched servo drive/amplifier.
-
Ensure regenerative resistor sizing (XTL-230-18) matches total kinetic energy of decelerating load.
-
Verify feedback device compatibility (resolver vs. encoder vs. SFD) between motor and drive before installation.
-
For legacy products (Goldline B-series, SERVOSTAR 400), confirm availability of replacement cables and mating connectors.
-
Ground all equipment to protective earth (PE) per local electrical code and Kollmorgen installation manuals.
