Product Parameters

• Manufacturer / Brand: Kollmorgen (a Regal Rexnord company).
• Series: AKM (High-Performance Servo Motors).
• Model: AKM42E-EKGNR-01.
• Frame Size: AKM 42 (indicating a specific motor diameter, approximately 42mm).
• Motor Type: Permanent Magnet Synchronous Motor (PMSM).
• Performance Level: The “E” in the model often denotes a specific performance tier or winding variant within the frame size.
• Feedback System: The suffix “-EKGNR-01” specifies the integrated feedback device, which is a high-resolution single-turn or multi-turn encoder (typically a sin/cos encoder or a resolver).
• Rated Speed & Torque: Specific values (e.g., 3000 RPM, specific Nm continuous torque) defined in the detailed datasheet for this exact model code.
• Voltage Constant: Defined in V/kRPM, which is crucial for selecting the correct bus voltage on the matching drive.
• Torque Constant: Defined in Nm/A, used to calculate the required drive current.
• Protection Class: Typically IP65 (dust-tight and protected against water jets), suitable for most industrial settings.
• Connector: Features a standardized motor connector (e.g., a circular metal connector) for power and feedback.

Advantages and Features

• High Torque Density: Delivers high continuous and peak torque from a compact frame size, allowing for smaller mechanical designs and higher machine performance.
• Low Cogging & Smooth Operation: Advanced magnetic design minimizes cogging torque, enabling extremely smooth rotation at low speeds, which is critical for precision applications like dispensing or scanning.
• Excellent Dynamic Response: Low rotor inertia allows for very high acceleration and deceleration rates, reducing cycle times in pick-and-place or indexing applications.
• High Reliability & Durability: Built with high-quality materials and bearings, designed for long service life in demanding 24/7 operation.
• Seamless System Integration: Designed as part of the complete Kollmorgen ecosystem, ensuring optimal performance and simplified tuning when paired with an AKD or AKI series servo drive.

Application Cases in Industry

• Semiconductor Manufacturing: Used in wafer handling robots, stepper motors for photolithography stages, and die bonder positioning axes where precision and cleanliness are paramount.
• Packaging Machinery: Drives rotary filling heads, precise cut-off knives, and high-speed pick-and-place units on cartoning and blister packaging lines.
• Printing & Converting: Provides precise registration control for printing cylinders and tension control for webs in digital and flexographic printing presses.
• Medical Automation: Powers the smooth and accurate movements in automated diagnostic equipment, liquid handling robots, and surgical device actuators.
• Advanced Robotics: Serves as the joint actuator in collaborative robots (cobots) and high-speed delta robots used for sorting and assembly.

Comparison with Competing Products

Direct competitors include servo motors from Beckhoff (AM8000 series), Bosch Rexroth (IndraDrive Mi), and Yaskawa (SGM7V series). The KOLLMORGEN AKM42E-EKGNR-01 distinguishes itself through its exceptional smoothness at low speed (low cogging) and its reputation for high reliability and quality. Compared to a standard asynchronous (induction) motor with a gearbox, the AKM42E offers vastly superior controllability, precision, and dynamic response in a direct-drive form factor. Within the servo motor market, Kollmorgen is often positioned as a premium provider, with the AKM series competing favorably on performance metrics, sometimes at a higher initial cost that is justified by longevity and precision in critical applications.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. Select the KOLLMORGEN AKM42E-EKGNR-01 when designing a high-performance motion axis that requires excellent low-speed smoothness, high acceleration, or compact size.
  2. Carefully analyze the motion profile (speed, torque vs. time) to ensure the motor’s continuous and peak torque ratings are sufficient, with appropriate safety margins.
  3. Always select a compatible Kollmorgen servo drive (e.g., AKD series) using the manufacturer’s sizing software (e.g., Kollmorgen Motioneering) to ensure optimal performance and thermal management.
• Precautions:
  1. Drive Compatibility: The motor must be paired with a drive specifically configured to work with its feedback type (the “-EKGNR-01” suffix). Incorrect drive configuration can damage the feedback system.
  2. Mechanical Installation: Adhere strictly to specified mounting tolerances and coupling alignment. Misalignment is a leading cause of premature bearing failure and vibration.
  3. Thermal Management: Ensure the motor is adequately sized so that it operates within its thermal limits. Consider external forced cooling if the duty cycle is very demanding. Monitor motor temperature via the drive if possible.
  4. Cable and Connector Handling: Use only recommended motor feedback and power cables. Protect the motor connector from contamination and strain. Improper cable routing can introduce noise into the feedback signal.
  5. Model Code Precision: The full model number AKM42E-EKGNR-01 is critical. Variations in the suffix indicate different windings, feedback types, or shaft options. Verify the exact code against your requirements and source from authorized Kollmorgen distributors.
