KEM-4V150-KE9NCB Kollmorgen Essentials 240/480VAC 1500W Servo Motor
Sku#: KEM-4V150-KE9NCB
The Kollmorgen KEM-4V150-KE9NCB Servo Motor is a 1.5 kW, 240/480 VAC high-performance servo motor engineered for demanding industrial automation applications. Part of the Kollmorgen Essentials™ product family, this 108 mm IEC-frame motor delivers excellent torque density, smooth motion, and long-term reliability in a cost-optimized design.
This model provides 5.9 Nm continuous stall torque and 13.3 Nm peak torque at 480 VAC, enabling high-precision control for mid- to high-power applications such as packaging equipment, material handling axes, robotics, and automated machinery. With a maximum mechanical speed of 5000 rpm, it offers strong acceleration and responsive performance across a wide operating range.
The motor includes Kollmorgen’s SFD-M Smart Feedback Device, supplying 24-bit single-turn and 16-bit battery-free multi-turn absolute feedback. This ensures < ±1 arc-minute accuracy and supports automatic motor recognition, dramatically reducing commissioning time when paired with Kollmorgen Essentials or AKD-series drives.
A rotatable M23 hybrid connector integrates power and feedback into a single IP54-rated interface, minimizing wiring effort and simplifying installation. The IEC-standard mount and dual keyway shaft kit enable easy mechanical integration and support both keyed and smooth-shaft configurations.
Designed for robust industrial environments, the KEM-4V150-KE9NCB uses Class F (155 °C) insulation, a PTC thermal sensor, and is designed for long duty cycles at 100 °C winding rise. The motor is IP54-rated and compatible with an optional shaft-seal kit for upgraded IP65 protection.
When combined with Kollmorgen Essentials servo drives, this motor supports EtherCAT®, PROFINET®, and EtherNet/IP™ communication with single-cable connectivity—making it an excellent choice for OEMs seeking performance and simplicity.
