Product Description:

The AKM65P-ACCNDB-00 is a Synchronous servo motor produced by Kollmorgen that is intended for applications that necessitate precise control of position and speed. The servo motor is designed to deliver precise and dependable motion, that makes it suited for complex industrial automation.

The AKM65P-ACCNDB-00 servo motor has a stator size of 108 mm and produces 2.41 kW of rated power at 2000 RPM, with a rated torque of 11.5 Nm. With a peak current of 15.4 A, the motor can deliver a maximum torque of 29.1 Nm, and it operates continuously at 6.27 A. The prescribed values for the back EMF constant and torque constant are 47.3 Vrms/krpm and 0.74 Nm/Arms, respectively, with a margin of ±10 percent. Thanks to its five pole pairs, the servo motor can function reliably from -20°C to +40°C. At 0.061 Nm/krpm, the viscous suspension is measured, and at 0.077 Nm, the static friction is detected. Operating steadily during continuous duty cycles is made possible by the winding's thermal resistance to ambient heat of 0.45 °C/W and a thermal time constant of 31 minutes. By linking the rotor's speed to the stator's magnetic field, the feedback mechanism guarantees constant performance under all load conditions.

The AKM65P-ACCNDB-00 servo motor is designed for integration into systems that necessitate precision synchronization between the magnetic field of the stator and the rotor, which is crucial for precise control of speed and position. The servo motor is suitable for applications where efficiency and reliability are critical due to its optimized thermal management, low electrical resistance, and high torque density. This motor's adaptability in automation systems is boosted by its design, which allows for advanced feedback devices and many mounting options. Maintaining a consistent speed under load is an important characteristic that is essential for precision-driven processes.
