Kollmorgen 6SM37M-6000
Product Introduction:
The 6SM37M-6000 is a brushless DC servo motor from Kollmorgen’s SM Series product line. The “37” denotes a 37 mm frame size (diameter), “M” indicates a metric mounting configuration, and “6000” specifies the winding and feedback variant. This motor is a compact, high-performance servo motor designed for precision motion control in space-constrained applications such as medical devices, laboratory equipment, and small-format automation.

Structural Features:
- Aluminum alloy housing with silver anodized finish
- Precision ball bearings (sealed, lubricated for life)
- Smooth 5 mm shaft with set-screw locking
- M8 connector for power (U, V, W) and feedback (A+, A-, B+, B-, Z+, Z-, +5V, GND)
- Compact cylindrical form factor — ideal for tight spaces
Functional Features:
- High speed-to-torque ratio: 6000 RPM at 0.15 Nm continuous
- Incremental encoder provides velocity and position feedback
- Low rotor inertia enables fast acceleration/deceleration
- RS-422 differential output provides noise immunity up to 100 meters cable length
Applicable Industries:
- Medical device actuators (infusion pumps, surgical tools)
- Laboratory automation (pipetting, sample handling)
- Semiconductor inspection equipment
- Small pick-and-place machines
- Optical alignment stages
- Drone and UAV actuators (small format)
Installation Requirements:
- Mount using M3.5 screws on the 37 mm flange (4-hole pattern, 28 mm PCD)
- Use flexible coupling — max misalignment: 0.1 mm radial, 0.1° angular
- M8 connector torque: 0.5 Nm maximum
- Cable bend radius: minimum 25 mm
Usage Notes:
- Encoder signal: A+, A-, B+, B- (RS-422 differential), Z+, Z- (index pulse), +5V, GND
- Do not exceed 0.45 Nm peak torque for more than 5 seconds
- Ambient temperature limit: 45°C for continuous rated operation
- For IP65 rating, order optional seal kit (part number: SM-SEAL-37)
