KEM-2V300-KE9NCB Kollmorgen Essentials 120/240 VAC 3000W Servo Motor
Sku#: KEM-2V300-KE9NCB
The Kollmorgen KEM-2V300-KE9NCB Servo Motor is a powerful 3.0 kW, 138 mm IEC-frame servo motor from the Kollmorgen Essentials™ family—engineered for exceptional torque performance, smooth motion, and simplified integration. Ideal for high-demand automation, packaging, and material-handling applications, this motor provides a perfect balance of power, precision, and durability.
Operating from a 120 / 240 VAC single- or three-phase supply, the KEM-2V300-KE9NCB delivers 11.5 Nm continuous stall torque, 26.8 Nm peak torque, and speeds up to 4,000 rpm. Designed for energy efficiency and long service life, it combines high torque density with low inertia for faster acceleration and precise positioning in dynamic motion profiles.
The integrated SFD-M Smart Feedback Device provides 24-bit single-turn and 16-bit battery-free multi-turn absolute feedback, ensuring < ±1 arc-minute accuracy and plug-and-play configuration with Kollmorgen Essentials or AKD-series drives. This advanced feedback device includes onboard electronic nameplate data for automatic motor recognition and parameter setup.
Installation is streamlined through a rotatable M23 hybrid connector that consolidates power, brake, and feedback connections into one IP54-rated interface, reducing wiring complexity. The IEC-standard mounting interface and shaft key kit enable smooth or keyed shaft coupling in a single motor model, simplifying inventory and mechanical integration.
Built for industrial environments, this motor includes Class F insulation (155 °C), a PTC thermal sensor, and is rated for 100 °C winding rise at 40 °C ambient. Optional IP65 protection is available using the KEM-150-400-SSK shaft-seal kit. When paired with a Kollmorgen Essentials servo drive, the system supports multi-Ethernet communication protocols (EtherCAT®, PROFINET®, and EtherNet/IP™) and single-cable operation—providing powerful, precise, and efficient motion control for complex multi-axis systems.
