Kollmorgen 6SM37L-4.00 three-phase permanent magnet synchronous servo motor

Product Description

Kollmorgen 6SM37L-4.00 (6SM37L-4.000) is a 3-phase permanent magnet synchronous servo motor from Kollmorgen 6SM series, the classic compact brushless servo motor of Seidel. The rotor adopts NdFeB permanent magnet material with built-in resolver for position feedback. Featuring robust construction, low cogging torque and excellent dynamic response, it supports S1 continuous duty operation and can be matched with Kollmorgen SERVOSTAR servo drives. 24VDC electromagnetic brake is available as option. Widely adopted in high-precision positioning machinery. As a classic European servo product, it is commonly used in machine tools and automation lines.
