Product Description:
Kollmorgen manufactures the AKM41E-ACDNCA-0F. The AKM41E-ACDNCA-0F synchronous servo motor has a well-balanced combination of mechanical and electromagnetic properties to meet the demands of high-precision industrial automation. With a peak stall torque of 6.28 Nm and a continuous stall torque of 2.02 Nm, this motor has both momentary and sustained torque, which is required for tasks that involve abrupt transients and static loads. These torque values define the maximum mechanical stress the motor can withstand before degrading thermally, and whether it’s suitable for repeated force applications like robotic articulation and press feeding systems. It's heat management and precisely designed winding architecture that prevents long-term performance degradation during high duty cycles is which allows it to deliver this torque without overheating.
Fast acceleration and deceleration with no delay is possible with its low rotor inertia of 0.000081 kg-m2, which further improves its dynamic response. In systems like semiconductor production or vision-guided pick-and-place units where quick positioning changes and fast settling times are critical, this is key. High conversion efficiency from input current to output torque is indicated by a torque constant of 0.71 Nm/Arms, which improves torque production efficiency. When choosing amplifiers and designing motion control loops, system designers must balance torque delivery and power budget constraints. This ratio is critical. Accurate velocity control in closed loop is critical to maintain synchronization in coordinated multi-axis systems. At the same time, the back electromotive force constant of 45.6 Vrms/krpm provides reliable voltage feedback for a given shaft speed.
The long-term durability and integration readiness of the AKM41E-ACDNCA-0F are shown by its electrical and thermal characteristics. Higher efficiency and less thermal stress on insulating materials are achieved by the motor’s regulated internal heating under rated conditions, which is shown by its DC resistance of 6.02 ohms at 25°C. The thermal resistance of 0.97 °C/W allows for efficient heat dissipation, and the 13-minute thermal time constant describes the motor’s delayed thermal reaction under constant load, giving important protection time before thermal thresholds are crossed. The static friction of 0.014 Nm allows for better start behavior without overshoot, and at high speed, energy losses are minimized by the viscous damping coefficient of 0.009 Nm/krpm. All these values work together to provide precisely calibrated motion profiles and minimize thermal wear, making the motor suitable for automation systems that require accuracy and high speed.
