KEM-4V300-KE92CB Kollmorgen Essentials 240/480 VAC 3000W Servo Motor
Sku#: KEM-4V300-KE92CB
The Kollmorgen KEM-4V300-KE92CB Servo Motor is a high-power 3.0 kW, 240/480 VAC servo motor engineered for demanding industrial applications requiring strong continuous torque, smooth motion, and integrated holding capability. As part of the Kollmorgen Essentials™ series, this motor delivers dependable performance in a rugged 138 mm IEC-frame, making it ideal for machine builders seeking high output without compromising reliability.
The KEM-4V300-KE92CB provides 11.4 Nm continuous stall torque (with brake) and 27.3 Nm peak torque at 480 VAC, along with a maximum mechanical speed of 4000 rpm. This makes it well-suited for heavy-duty applications such as large packaging machinery, gantry axes, robotics, materials processing, and industrial automation requiring significant torque reserves.
This model includes a 24 VDC failsafe holding brake, adding load-holding capability for vertical axes, precision holds, and safety-critical motion profiles. Kollmorgen’s SFD-M Smart Feedback Device provides 24-bit single-turn and 16-bit battery-free multi-turn absolute feedback, ensuring < ±1 arc-minute accuracy. Auto-recognition through the electronic nameplate drastically shortens setup time when paired with Kollmorgen Essentials or AKD drives.
Installation is simplified through a single rotatable M23 hybrid connector, combining power, brake, and feedback in one IP54-rated interface. The motor includes the Essentials standard mounting interface and a shaft key kit supporting both keyed and smooth shaft configurations.
Designed for industrial durability, the motor features Class F (155 °C) insulation, a PTC thermal sensor, 100 °C winding rise, and is rated IP54 (upgradeable to IP65 with an optional shaft seal). The robust frame and high-performance thermal design ensure reliable operation in continuous-duty, high-load environments.
When integrated with Kollmorgen Essentials drives, the KEM-4V300-KE92CB supports EtherCAT®, PROFINET®, and EtherNet/IP™, enabling a powerful, fully integrated automation solution with single-cable connectivity.
