Product Description:

The 6SM 37M-6000 is a synchronous servo motor built by Kollmorgen for the 6SM Synchronous Servo Motors series. It serves as the rotary actuator in motion axes that require accurate speed tracking and tight position control. Integrated feedback supplies rotor position data, while the IM B5 (V1, V3) flange arrangement allows the motor to mount to compatible gearboxes or machine frames.

During continuous duty, the motor develops 0.5 kW of mechanical output while operating at a rated speed of 6000 rpm. This output is produced with a rated shaft torque of 0.8 Nm and a steady-state phase current of 1.5 A. Standstill capability reaches 1 Nm of static torque with 1.6 A, providing holding force when the axis is stationary. The electrical characteristics include a phase inductance of 21 mH and a winding resistance of 12.8 Ω, which affect current rise time and copper loss. A two-pole resolver supplies rotor angle data to the drive, allowing precise interpolation for closed-loop motion control. The resolver signals help the drive regulate speed and position during changing load conditions.

Transient loads are supported by a peak current limit of 6.5 A, enabling short acceleration bursts while keeping current within the permitted range. The housing has an IP65 ingress protection rating, preventing dust intrusion and protecting internal components from low-pressure water jets. The magnetic circuit has 6 poles, which establishes the electrical frequency required for synchronous operation. A torque constant of 0.62 Nm/A indicates the relationship between phase current and generated torque. Back electromotive force is rated at 38 V/1000 rpm, allowing the connected drive to account for generated voltage at increasing motor speeds. This value also supports appropriate DC bus and regenerative braking component selection for the intended operating range.
