Product Details:

KOLLMORGEN 6SM57M-3.000 is a permanent magnet synchronous servo motor of the classic Seidel 6SM series, frame size 57mm, rated speed 3000RPM and rated power 1.4kW. It is widely matched with Seidel 64WKS and SERVOSTAR series servo drives, applied on CNC machine tool feed axes, printing machinery, packaging equipment and rotary positioning platforms, offering stable continuous torque and fast dynamic response for medium-load closed-loop motion control axes requiring high positioning accuracy. It can be equipped with resolver or encoder feedback according to configuration, and optional 24V DC holding brake for position locking after stop.

This servo motor adopts high-performance rare earth magnet design, optimized magnetic circuit reduces cogging torque to ensure smooth running at low speed. The standard protection grade is IP65 for housing and shaft seal, suitable for workshop environments with oil mist and dust. It uses separate power connector and feedback connector structure, convenient for on-site wiring and maintenance. The rotor is dynamically balanced for high-speed operation, with low vibration and low noise characteristics. Multiple shaft and flange options are available to fit different mechanical installation interfaces.

Professional technicians can set current limit, speed loop gain and braking parameters on the supporting servo drive according to load requirements. Matched with Kollmorgen dedicated servo amplifier, it can realize torque, speed and position closed-loop control. When abnormal conditions such as overload, overheating or feedback disconnection occur, the drive will cut off output rapidly to protect the motor winding and internal feedback component from damage. The robust mechanical structure is anti-vibration, adapting to long-time cyclic continuous operation of industrial equipment.

This KOLLMORGEN 6SM57M-3.000 servo motor has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy Seidel motion systems. Maintenance personnel can complete replacement safely after power cut, and the original drive and mechanical installation dimensions can be kept consistent.

It is a widely used medium-size Seidel servo motor spare part, frequently selected for maintenance and renovation of old CNC and automation equipment.
