Introduction: Solving Precision Motion Challenges
When industrial applications demand rapid acceleration and precise positioning, the Mitsubishi HG-KR053 servo motor provides a reliable solution. This low-inertia, small-capacity motor from the MELSERVO series handles demanding motion tasks with efficiency.
Technical Specifications Breakdown
The HG-KR053 delivers a rated speed of 3000 rpm and a maximum speed of 6000 rpm, enabling fast cycle times. Its rated output power is 0.05 kW, with a rated torque of 0.16 Nm and a maximum torque of 0.56 Nm. The power rate at continuous rated torque reaches 5.63 kW/s, ensuring quick acceleration. A rated current of 0.9 A and maximum current of 3.2 A support efficient operation. The recommended load-to-motor inertia moment ratio of 17 times or less maintains stability.
Industry Applications
In pick-and-place systems, the HG-KR053's low inertia allows rapid start-stop cycles, reducing cycle times. For packaging machinery, its 22-bit encoder (resolution: 4194304 pulses/rev) provides precise position feedback, ensuring consistent product placement. In labeling equipment, the motor's high-speed capability up to 6000 rpm enables fast line speeds without sacrificing accuracy.
Installation & Setup Guidance
Mount the HG-KR053 securely on a rigid surface to minimize vibration. Ensure proper alignment with the driven load to avoid excessive bearing stress. Connect the 22-bit encoder cable carefully, following Mitsubishi's wiring diagrams. Verify that the ambient temperature stays within 0 to 40°C (32 to 104°F) and humidity between 10% to 80% RH (non-condensing). Use only in indoor environments free from corrosive gases, inflammable gases, oil mist, or dust.
Maintenance & Reliability
Inspect the motor periodically for dust accumulation on the totally-enclosed natural cooling system. Check the shaft seal for wear if operating in dusty environments. The IP65 rating protects against dust and moderate water exposure, but avoid direct water jets. Store the motor in a temperature range of -15 to 70°C (5 to 158°F) and humidity of 10% to 90% RH (non-condensing) when not in use.
Compatibility & Integration
The HG-KR053 integrates with Mitsubishi MELSERVO servo drives and controllers. Its 22-bit encoder supports both absolute position and incremental systems, simplifying integration into new or existing motion control networks. Verify drive compatibility with your specific controller model before ordering.
Selection Guide & Purchasing Advice
Before purchasing, confirm that the HG-KR053's rated torque of 0.16 Nm and maximum torque of 0.56 Nm meet your application requirements. Ensure the load-to-motor inertia ratio does not exceed 17 times. Contact SpareTechPLC for current availability and lifecycle status.
