KEM-2V250-KE92CB Kollmorgen Essentials 120/240 VAC 2500W Servo Motor
Sku#: KEM-2V250-KE92CB
The Kollmorgen KEM-2V250-KE92CB Servo Motor is a powerful and reliable 2.5 kW, 108 mm IEC-frame motor in the Kollmorgen Essentials™ series—engineered for precision, durability, and simplified integration in demanding automation systems. Designed to provide exceptional torque output and smooth performance, it’s ideal for OEMs and machine builders seeking a cost-effective, high-performance servo solution.
Operating from a 120 / 240 VAC single- or three-phase supply, the KEM-2V250-KE92CB delivers 10.1 Nm continuous stall torque (with brake), 23.4 Nm peak torque, and speeds up to 5,000 rpm. It includes a 24 V DC failsafe holding brake with 14.5 Nm static holding torque, providing secure load retention in vertical or safety-critical applications.
The integrated SFD-M Smart Feedback Device offers 24-bit single-turn and 16-bit battery-free multi-turn absolute feedback, ensuring < ±1 arc-minute accuracy and simplified plug-and-play setup with Kollmorgen Essentials or AKD-series drives. The onboard electronic nameplate automatically communicates motor parameters to the drive, reducing commissioning time and configuration errors.
Installation is streamlined with a rotatable M23 hybrid connector that combines power, brake, and feedback connections into one IP54-rated interface. The IEC-standard mount and shaft key kit allow smooth or keyed shaft options in a single model—helping minimize inventory complexity and simplify system design.
This motor features Class F insulation (155 °C), a PTC thermal sensor, and 100 °C winding rise for long-term reliability in industrial conditions. The optional KEM-150-400-SSK shaft-seal kit enables IP65 protection for harsh environments.
When paired with Kollmorgen Essentials drives, the KEM-2V250-KE92CB supports multi-Ethernet communication protocols (EtherCAT®, PROFINET®, EtherNet/IP™), single-cable operation, and rapid setup through Kollmorgen Workbench software—delivering consistent performance in packaging, robotics, conveyors, and material forming systems.
