Product Introduction:
The M-607-B-A3 is a compact, high-torque-density AC servo motor from Kollmorgen’s M-Series lineup. It is designed for applications requiring high dynamic response in a small footprint, with integrated feedback and optimized for use with S200, AKD, and S700 series drives.
Technical Specifications:
| Parameter | Value |
|---|---|
| Frame Size | M-607 (NEMA 23 equivalent) |
| Stator Outer Diameter | 60 mm (approx.) |
| Stack Length | 70 mm (approx.) |
| Rated Torque (Continuous) | 2.39 Nm |
| Peak Torque | 7.17 Nm (3× rated, 10 s) |
| Rated Speed | 3000 RPM (continuous) |
| Max Speed | 4500 RPM |
| Rated Power | ~750 W |
| Winding Code | B (Rated voltage: 200–480 V AC) |
| Connector Type | A3 (M23 12-pin military-style connector) |
| Feedback Device | Single-turn absolute encoder (EnDat 2.2 / BiSS-C, 128–2048 lines) |
| Holding Brake | No (B = without brake) |
| Insulation Class | Class F (155°C) |
| IP Rating | IP65 (with optional seal kit) / IP54 (standard) |
| Weight | ~1.8 kg |
| Shaft Type | Keyed shaft with D-cut, 14 mm diameter |
| Bearings | Deep groove ball bearings (sealed) |
Structural Characteristics:
- Aluminum housing with anodized finish for corrosion resistance
- High-energy SmCo magnets (Samarium Cobalt) for high-temperature operation
- Skew-slot stator design for reduced cogging torque
- Integrated temperature sensor (PTC/KTY) in winding
Performance Parameters:
| Parameter | Value |
|---|---|
| Torque Constant (Kt) | 0.76 Nm/A (typical) |
| Back-EMF Constant (Ke) | 7.6 V/krpm (typical) |
| Rotor Inertia | ~18 × 10⁻⁶ kg·m² |
| Mechanical Time Constant | ~8 ms |
| Electrical Time Constant | ~2.5 ms |
Advantages:
- High torque-to-inertia ratio for fast acceleration
- Wide speed range with constant torque up to 3000 RPM
- Robust connector (A3) for harsh industrial environments
- SmCo magnets maintain performance at elevated temperatures
Applicable Industries:
Pick-and-place robots, small CNC axes, semiconductor wafer handling, medical devices, lab automation
Installation Requirements:
- Mount using 4× M6 mounting holes on the front flange
- Ensure shaft coupling is backlash-free (bellows or Oldham coupling recommended)
- Apply torque: 2.5 Nm on mounting bolts
- Verify encoder cable routing — minimum bend radius: 50 mm
Usage Notes:
- Do not exceed 4500 RPM — mechanical overspeed will damage bearings
- Do not apply axial load > 50 N on the shaft
- Use Kollmorgen Workbench for commissioning and parameter optimization
