KEM-4V400-KE92CB Kollmorgen Essentials 240/480 VAC 4000W Servo Motor
Sku#: KEM-4V400-KE92CB
The Kollmorgen KEM-4V400-KE92CB Servo Motor is a high-power 4.0 kW, 240/480 VAC servo motor designed for heavy-duty industrial automation requiring high torque, precise motion control, and integrated load-holding capability. As part of the Kollmorgen Essentials™ family, this model delivers exceptional robustness in a 138 mm IEC-frame, making it ideal for advanced machinery operating under continuous or demanding loads.
This motor provides 17.2 Nm continuous stall torque (with brake) and an impressive 40.5 Nm peak torque at 480 VAC. With a maximum mechanical speed of 4000 rpm, it excels in high-load, high-precision tasks such as gantry systems, large robotic joints, presses, forming machinery, and heavy conveyor or indexing applications.
The integrated 24 VDC failsafe holding brake ensures secure load support for vertical axes and safety-critical positioning. Kollmorgen’s SFD-M Smart Feedback Device supplies 24-bit single-turn plus 16-bit battery-free multi-turn absolute feedback, enabling < ±1 arc-minute positioning accuracy and auto-recognition when connected to Kollmorgen Essentials or AKD-series drives.
A single M23 hybrid connector consolidates power, brake, and feedback wiring into an IP54-rated interface, simplifying wiring and machine integration. The motor incorporates Class F (155 °C) insulation, a PTC thermal sensor, and a 100 °C winding rise for durability in continuous-duty environments. Standard IP54 protection can be upgraded to IP65 using an optional shaft-seal kit.
Designed for modern automation, the KEM-4V400-KE92CB pairs seamlessly with Kollmorgen Essentials drives, supporting EtherCAT®, EtherNet/IP™, and PROFINET® motion systems with single-cable servo architecture for simplified installation.
