KEM-2V040-KE92CB Kollmorgen Essentials 120/240 VAC 400W Servo Motor
Sku#: KEM-2V040-KE92CB
The Kollmorgen KEM-2V040-AC92CB Servo Motor is a 400 W, 58 mm-frame model in the Kollmorgen Essentials™ family—built to deliver precision motion performance, simplified installation, and dependable operation for OEM and industrial automation applications.
Operating from a 120 / 240 VAC single- or three-phase supply, this motor provides 1.32 Nm continuous torque with brake, 3.96 Nm peak torque, and speeds up to 6,000 rpm. It includes a 24 V DC failsafe holding brake, providing 1.42 Nm static holding torque—ideal for vertical or safety-critical axes.
The KEM-2V040-AC92CB integrates Kollmorgen’s advanced SFD-M Smart Feedback Device, offering 24-bit single-turn and 16-bit multi-turn absolute feedback without batteries. This system ensures high positional accuracy (< ± 1 arc-min typical) and enables plug-and-play setup when connected to Kollmorgen Essentials or AKD-series drives.
Designed for ease of integration, the motor uses a rotatable M23 hybrid connector combining power, brake, and feedback into a single IP54-rated interface. The IEC-standard mount and shaft key kit allow both keyed and smooth shaft coupling from a single model, streamlining inventory. For environments requiring greater protection, an optional IP65 shaft-seal kit (KEM-020-040-SSK) is available.
With Class F insulation (155 °C), a PTC thermal sensor, and conservative 100 °C winding rise rating, the KEM-2V040-AC92CB ensures long-term durability and consistent performance. Paired with Kollmorgen Essentials drives, it enables single-cable connectivity, seamless multi-Ethernet protocol compatibility (EtherCAT®, PROFINET®, EtherNet/IP™), and rapid commissioning via Kollmorgen Workbench.
This servo motor is a compact, robust choice for packaging, material-handling, and general automation systems that demand smooth motion, integrated safety, and exceptional reliability.
