KEM-4V040-KE92CB Kollmorgen Essentials 240/480 400W Servo Motor
Sku#: KEM-4V040-KE92CB
The Kollmorgen KEM-4V040-KE92CB Servo Motor delivers precise, efficient, and reliable performance in a compact 84 mm IEC-frame design. As part of the Kollmorgen Essentials™ family, this 400 W, 240/480 VAC servo motor integrates advanced feedback, a built-in holding brake, and simplified connectivity—ideal for OEMs and industrial machine builders seeking high-performance motion control in a value-driven package.
Providing 1.22 Nm continuous stall torque (with brake), 3.96 Nm peak torque, and speeds up to 6,000 rpm, this model combines energy efficiency with excellent torque linearity. The integrated 24 V DC failsafe holding brake delivers 1.42 Nm static holding torque, offering dependable load holding in vertical-axis or safety-critical applications.
At its core is Kollmorgen’s advanced SFD-M Smart Feedback Device, which provides 24-bit single-turn and 16-bit battery-free multi-turn absolute feedback, enabling < ±1 arc-minute accuracy. With built-in electronic nameplate data, the SFD-M simplifies setup by allowing plug-and-play motor recognition when paired with Kollmorgen Essentials or AKD-series drives.
The motor features a rotatable M23 hybrid connector, combining power, brake, and feedback into one IP54-rated interface for faster wiring and easier maintenance. Its IEC-standard mount and shaft key kit enable both keyed and smooth shaft configurations from a single model—reducing system complexity and part count.
Engineered for durability, the KEM-4V040-KE92CB features Class F insulation (155 °C), a PTC thermal sensor, and 100 °C winding rise for reliable operation in demanding environments. With IP54 protection standard (upgradeable to IP65 using the KEM-075-100-SSK shaft-seal kit), it’s designed for long life in industrial settings.
When combined with a Kollmorgen Essentials servo drive, this motor provides multi-Ethernet compatibility (EtherCAT®, PROFINET®, EtherNet/IP™), single-cable connectivity, and seamless integration—making it ideal for packaging, robotics, and general automation applications requiring precision and performance.
