KEM-2V040-KE9NCB Kollmorgen Essentials 120/240 VAC 400W Servo Motor
Sku#: KEM-2V040-KE9NCB
The Kollmorgen KEM-2V040-KE9NCB Servo Motor is part of the Kollmorgen Essentials™ family—combining performance, efficiency, and value in a compact 58 mm IEC-frame design. Operating from a 120/240 VAC single- or three-phase supply, this model delivers 400 W continuous output power, 1.37 Nm continuous torque, and 3.96 Nm peak torque, with speeds up to 6,000 rpm.
The KEM-2V040-KE9NCB is equipped with Kollmorgen’s SFD-M Smart Feedback Device, providing 24-bit single-turn and 16-bit battery-free multi-turn resolution with onboard electronic nameplate data for instant plug-and-play recognition when paired with Kollmorgen Essentials or AKD-series drives. The integrated SFD-M reduces wiring and installation time by combining power, brake, and feedback in a single rotatable M23 hybrid connector.
This servo motor features an IEC-standard mount, Class F insulation system (155 °C), and a conservatively rated 100 °C winding temperature rise, ensuring reliable performance and long service life. A PTC thermistor provides thermal protection, while the IP54 housing (upgradeable to IP65 with the optional KEM-020-040-SSK shaft-seal kit) offers robust protection for industrial environments.
When paired with a Kollmorgen Essentials servo drive, the KEM-2V040-KE9NCB provides seamless single-cable integration and compatibility with EtherCAT®, PROFINET®, and EtherNet/IP™ control platforms. It’s ideal for packaging machinery, material handling, and light-automation systems requiring compact high-performance motion.
