KEM-4V040-KE9NCB Kollmorgen Essentials 240/480 VAC 400W Servo Motor
Sku#: KEM-4V040-KE9NCB
The Kollmorgen KEM-4V040-KE9NCB Servo Motor delivers efficient, precise, and reliable motion performance for modern automation systems. As part of the Kollmorgen Essentials™ family, this 400 W, 240/480 VAC servo motor combines compact design, high torque density, and plug-and-play simplicity—making it ideal for OEMs and machine builders seeking dependable motion at an exceptional value.
This 84 mm IEC-frame motor provides 1.27 Nm continuous stall torque, 3.96 Nm peak torque, and speeds up to 6,000 rpm. Engineered for smooth operation and long life, it features Kollmorgen’s SFD-M Smart Feedback Device, a 24-bit single-turn and 16-bit battery-free multi-turn absolute encoder that offers < ±1 arc-minute accuracy and automatic configuration when paired with Kollmorgen Essentials or AKD-series drives.
The rotatable M23 hybrid connector integrates power, feedback, and brake wiring into a single IP54-rated connection, reducing cabling and simplifying installation. With an IEC-standard mount and interchangeable shaft key kit, the KEM-4V040-KE9NCB supports both keyed and smooth shaft coupling in a single model—helping to streamline inventory and improve system flexibility.
Designed for industrial reliability, it includes Class F insulation (155 °C), a PTC thermal sensor, and a 100 °C winding temperature rise for long-term durability. The motor’s standard IP54 protection can be upgraded to IP65 with the optional KEM-075-100-SSK shaft-seal kit.
When used with Kollmorgen Essentials drives, this motor supports EtherCAT®, PROFINET®, and EtherNet/IP™ control protocols, ensuring easy integration and optimal performance in packaging, robotics, material handling, and general automation systems.
