Product Description:

The AKM41E-ACDNA-0F servo motor is engineered for precision and reliability, featuring a continuous stall torque of 2.02 N-m and a peak stall torque of 6.28 N-m for demanding applications. This motor is part of a product lineup designed to meet the needs of modern industrial automation, supporting efficient and precise motion control through its robust design. The motor achieves a maximum speed of 6000 RPM when operated at 480 VAC, which allows for adaptable use in different operations. It can deliver a rated power of 244 Watts when running to 120 VAC, making it helpful for systems of different power needs through voltage level adjustments.

An important aspect of the AKM41E-ACDNA-0F servo motor is its electrical characteristics that enable precise control. It has a torque constant of 0.71 N-m/arms and a back EMF constant of 45.6 vrms/krpm, which are essential for accurate torque and speed regulation. The motor has specific current needs, requiring a continuous stall current of 2.85 arms and a peak stall current of 11.4 arms to achieve its maximum performance. The rotor's design is indicated by its rotor inertia of 0.000081 kg-m², which is critical when calculating how the motor's speed and torque respond to input.

Other important technical details, the AKM41E-ACDNA-0F is built to handle real-world conditions, having a thermal resistance of 0.97 °C/watt and a thermal time constant of 13 minutes. These characteristics are key to preventing problems from heat, which makes sure the motor stays reliable even with continuous use. The static friction (less shaft seal) is 0.014 N-m, which indicates the small amount of force needed for operation, and the viscous damping is 0.009 N-m/krpm, which is very important for balancing the machine.
