Product Description:

Kollmorgen AKMH33E-ACKNCA1K Servo Motor generates a constant stall torque of 2.51 Nm and it is designed with the robust Back EMF Constant of 70.6 Vrms / krpm which results in smooth regulation and reliability of feedback that achieves a balance of torque density and electrical performance.

The AKMH33E-ACKNCA1K stainless motor offers flexible installation options with cable lengths ranging from 1 to 15 meters in one meter increments which allows users to customize connectivity based on their application requirements and structural limitations. This motor is also powered by an open keyway shaft design which provides a secure and efficient mechanical coupling to limit backlash and therefore it is applicable in high performance precision torque transmission requirements and it is capable of a maximum of 10.32 amperes that guarantees high acceleration and quick control. It contains a smart feedback device that provides proper position and speed feedback and it contains long wearing EPDM O-rings that provide good sealing and moisture and dust ingress avoidance. It also has a recommended maximum torque of 10.19 nm owing to which high load applications are possible, and with a stack length of the rotor of 3 and frame size of 3, it ensures the compact yet powerful footprint and fits into most standard mounting arrangements.

This AKMH33E-ACKNCA1K stainless servomotor is formed to provide extended durability in steady operating conditions as well as its efficiency and thermal stability are not affected by its steady stall current of 2.34 Arms. It has a good balance of power and manageable weight (5.9 kilograms) and can be used in different industrial and automation systems.

Frequently Asked Questions about AKMH33E-ACKNCA1K:

Q: How does the open keyway shaft design of the AKMH33E-ACKNCA1K improve torque transmission?

A: The open keyway shaft ensures secure coupling, minimizing mechanical slip during high torque transfer. This improves efficiency and reduces vibration in dynamic load applications.

Q: Why is the Smart Feedback Device (SFD3) used in the AKMH33E-ACKNCA1K motor?

A: The SFD3 provides high-resolution position and speed feedback with reduced wiring complexity. This enhances signal reliability and simplifies installation.

Q: How does the IP-rated EPDM O-ring material contribute to the AKMH33E-ACKNCA1K's durability?

A: The EPDM O-rings provide superior sealing against water, dust, and contaminants. This extends the motor's operational life in harsh industrial environments.

Q: What makes the 1.09 Nm/Arms torque constant important in the AKMH33E-ACKNCA1K motor?

A: This torque constant allows for predictable torque output relative to input current. It simplifies motor control tuning and system optimization.

Q: Why is the 3-stack rotor length used in the AKMH33E-ACKNCA1K servo motor?

A: A 3-stack rotor increases magnetic interaction, improving torque density without enlarging motor size. This helps achieve higher performance in compact spaces.
