Kollmorgen 6SM-77S-3.000-09-V/12
Product Introduction:
The 6SM series (also known as Kollmorgen Seidel 6SM) are three-phase brushless synchronous servo motors with rare-earth neodymium permanent magnet rotors, optimized for high dynamic response and compact installation. The 6SM-77S-3.000-09-V/12 denotes frame 77 mm, S-length (medium), 3000 min⁻¹ rated speed, 9-pole resolver or encoder feedback (V = resolver/encoder variant), winding code 12.
