Description

The Kollmorgen SAM-DA-400-07B-P4N-F is a high-performance permanent magnet AC servo motor engineered for demanding industrial motion control applications requiring exceptional dynamic response, precision, and reliability. As part of Kollmorgen’s SAM (Servo Automation Motor) DA series—designed specifically for 400 V class drive systems—the Kollmorgen SAM-DA-400-07B-P4N-F delivers 7.0 Nm of continuous torque and up to 21 Nm peak torque in a compact P4N frame size, making it ideal for space-constrained yet high-power applications such as robotic arms, CNC machining centers, and automated assembly lines.

Built on Kollmorgen’s decades of expertise in electromechanical design, the Kollmorgen SAM-DA-400-07B-P4N-F features low rotor inertia for rapid acceleration/deceleration, high-resolution feedback integration, and robust thermal management via an optimized stator winding and finned housing. The “F” suffix denotes factory-installed single-turn absolute encoder (EnDat 2.2 or BiSS-C compatible), while the “B” indicates an integrated electromagnetic fail-safe brake—critical for vertical-axis safety and holding during power loss. Fully compatible with Kollmorgen’s AKD, S700, and legacy S200/S600 servo drives, the Kollmorgen SAM-DA-400-07B-P4N-F ensures seamless system integration, reduced commissioning time, and long-term operational stability in 24/7 production environments.

Main Features and Advantages

High power density in a compact footprint:
The Kollmorgen SAM-DA-400-07B-P4N-F packs 7 Nm of continuous torque into a P4N frame (90 mm flange), enabling machine builders to achieve high axis performance without increasing cabinet or robot arm size. Its axial length is minimized through optimized magnetic circuit design, reducing overall machine inertia.

Integrated safety and precision feedback:
Equipped with a factory-aligned absolute encoder (suffix “F”), the Kollmorgen SAM-DA-400-07B-P4N-F eliminates homing routines at startup—critical for robotic and packaging applications requiring immediate position awareness. The built-in brake (suffix “B”) provides failsafe holding during emergencies or power interruptions, meeting ISO 13849 PLd requirements when used in certified safety circuits.

Optimized for 400 V drive systems:
Unlike standard 230 V servos, the Kollmorgen SAM-DA-400-07B-P4N-F operates directly from 400 V DC bus voltage (derived from 400 V AC mains), reducing current draw by ~40% compared to 230 V equivalents. This lowers I²R losses, improves thermal efficiency, and allows longer cable runs without voltage drop issues—ideal for large-scale machinery.

Robust environmental protection:
With an IP65 rating, the Kollmorgen SAM-DA-400-07B-P4N-F withstands washdowns, dust, and oil mist common in food processing, metal cutting, and automotive plants. The shaft seal prevents ingress, while conformal-coated windings resist corrosion from airborne contaminants.

Seamless drive compatibility:
The motor is plug-and-play with Kollmorgen AKD and S700 servo drives using standard hybrid cables. Auto-recognition via electronic nameplate (stored in encoder memory) enables automatic parameter loading in WorkBench software—cutting setup time by up to 70%.

Application Field

The Kollmorgen SAM-DA-400-07B-P4N-F excels in high-dynamic automation tasks across multiple industries. In industrial robotics, it powers joint axes in SCARA and 6-axis arms where rapid cycle times and precise repeatability (<±0.02 mm) are essential—its integrated brake ensures safe arm parking during E-stop events. In CNC machining, the Kollmorgen SAM-DA-400-07B-P4N-F drives tool changers, rotary tables, and feed axes, leveraging its high torque-to-inertia ratio for smooth contouring at high speeds.

Packaging and converting machinery also benefit from this motor’s capabilities: in form-fill-seal lines, it controls film tension rollers and cut-off knives with microsecond-level responsiveness. In semiconductor handling equipment, the Kollmorgen SAM-DA-400-07B-P4N-F’s low cogging and smooth torque delivery prevent wafer slippage during high-acceleration transfers. Even in renewable energy test rigs—such as solar tracker simulators—the motor’s 400 V efficiency and thermal resilience ensure reliable operation under continuous load cycling. Wherever precision, safety, and uptime matter, the Kollmorgen SAM-DA-400-07B-P4N-F delivers industrial-grade performance.

Installation and Maintenance

Pre-installation preparation: Before mounting the Kollmorgen SAM-DA-400-07B-P4N-F, verify that the mechanical coupling and load are aligned within 0.05 mm TIR to avoid bearing stress. Ensure the brake power supply (24 V DC) is isolated from logic grounds and includes a flyback diode. Use only Kollmorgen-specified hybrid cables (e.g., TB-400 series) to maintain signal integrity and encoder resolution. Confirm that the drive firmware supports DA-series motors—older AKD versions may require update.

Maintenance recommendations: The Kollmorgen SAM-DA-400-07B-P4N-F is maintenance-free under normal conditions due to its sealed bearings and solid-state design. However, inspect the shaft seal and connector gasket annually in washdown environments for cracks or hardening. Test brake engagement force every 12 months using a torque wrench; replace if holding torque drops below 8 Nm. Monitor motor temperature via the drive’s thermal model—repeated overtemperature faults may indicate blocked ventilation or excessive duty cycle. Always store spare Kollmorgen SAM-DA-400-07B-P4N-F units in dry, temperature-controlled conditions to preserve bearing lubrication.
