Product Details:

KOLLMORGEN 6SM57S-3.000-G is a permanent magnet synchronous servo motor of the Seidel 6SM series, the G suffix indicates resolver feedback configuration. It has a frame size of 57mm, rated speed 3000RPM and rated power 0.94kW, widely matched with Seidel 64WKS series and SERVOSTAR servo drives. It is commonly used on CNC machine tool feed axes, printing machinery, packaging equipment and rotary positioning stations, delivering stable continuous torque and smooth low-speed operation for light and medium-load closed-loop motion control axes that require high positioning repeatability.

This servo motor adopts rare earth permanent magnet rotor design, optimized magnetic circuit effectively reduces cogging torque and ensures stable running performance at low speed. The resolver feedback structure provides strong anti-interference ability, suitable for environments with heavy electromagnetic noise, oil mist and dust. The housing and shaft seal reach IP65 protection grade. It is equipped with separate power connector and dedicated resolver feedback connector for convenient wiring and on-site maintenance. The rotor undergoes dynamic balance calibration for low vibration and low noise during high-speed operation. Optional 24V DC holding brake can be selected for position locking when power is off.

Technicians can configure current limit, speed loop gain and braking parameters on the matched servo drive according to different load conditions. When abnormal states such as overload, overheating or feedback signal loss occur, the supporting drive will quickly disable output and trigger fault alarm to protect the motor winding and internal resolver component from damage. The robust mechanical structure has good shock and vibration resistance, adapting to long-time cyclic continuous operation of industrial equipment.

This KOLLMORGEN 6SM57S-3.000-G servo motor has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy Seidel motion control 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 classic small-size Seidel servo motor spare part, widely used for maintenance and renovation of old CNC and automation motion axes.

Key specifications：KOLLMORGEN 6SM57S-3.000-G servo motor,0.94kW rated power,3000RPM rated speed,resolver feedback,IP65 protection,optional 24V DC brake. Operating temperature range: 0°C to +40°C. It undergoes winding insulation test, resolver signal inspection and no-load running test before shipment.

This 6SM57S-3.000-G servo motor can cooperate with Kollmorgen Seidel 64WKS series servo amplifiers to realize stable closed-loop speed and torque control.
