Product Description:
The 6SM 37VL-6000-09-G-6R is a synchronous servo motor manufactured by Kollmorgen within the 6SM Synchronous Servo Motors series. It delivers closed-loop rotary actuation to conveyors, indexing tables, and small machine-tool spindles in industrial automation. Resolver feedback guides the drive, while an integrated permanent-magnet holding brake secures the load during controlled stops or power-off conditions.
The motor delivers 1.2 kW of mechanical power when running at its rated speed of 6000 rpm. At this operating point, it draws 2.8 A of phase current and produces 2 Nm of continuous torque at the shaft. A standstill capability of 3 Nm lets the axis resist external forces without motion while energized. The permanent-magnet brake accepts a 24 V DC release signal, preventing drift when the drive is disabled. Two-pole resolver feedback supplies angular position information within each revolution, simplifying commutation. Electrical losses are influenced by a winding resistance of 3.65 Ω. The compact lamination stack allows heat to leave the stator quickly during continuous operation at nominal ratings.
Dynamic events are handled by a peak current limit of 15.2 A, allowing short bursts of acceleration. The electromagnetic design has a torque constant of 0.79 Nm/A, enabling the controller to translate demanded current into predictable load torque. Back-electromotive force is characterized by a voltage constant of 48 V/1000 rpm, which helps with bus-voltage sizing for regenerative events. A phase inductance of 8 mH attenuates current ripple and supports drive stability. The thermal model uses a 15-minute time constant to predict winding temperature during operation. The flange must remain below 65 °C to protect the insulation and bearings from excessive heat.
