Mitsubishi Motors AC Servo HG-KR053D 50W 3K RPM with D-CUT SHAFT
HG-KR053DDescription
The HG-KR053D is a compact, low-inertia AC brushless rotary servo motor engineered for high-precision, small-scale industrial motion control applications. With a 50W (0.05kW) rated output, it delivers reliable performance in a lightweight, space-efficient form factor (40mm × 40mm flange). The motor features a D-cut flat shaft for secure coupling, a built-in 22-bit absolute encoder (4,194,304 pulses/rev) for ultra-precise position feedback, and IP65 environmental protection for dust and water resistance. Designed for seamless integration with standard servo drives, it operates on a 200V AC class power supply and utilizes natural cooling for maintenance-free operation. Ideal for dynamic positioning, rapid acceleration/deceleration, and high-accuracy motion tasks.
HG-KR053D Key Features
Ultra-Low Inertia Design: Minimizes mechanical response time, enabling fast acceleration, deceleration, and precise dynamic control.
High-Resolution Absolute Encoder: 22-bit (4.19M pulses/rev) for exceptional positioning accuracy and zero loss of position on power-up.
High Torque-to-Weight Ratio: Rated torque of 0.16Nm and peak torque of 0.56Nm (350% of rated) for superior load handling.
Wide Speed Range: Rated speed of 3,000 rpm with a maximum speed of 6,000 rpm for flexible operation.
IP65 Environmental Protection: Fully sealed housing (except shaft end) for complete dust protection and resistance to low-pressure water jets.
Compact & Lightweight: 40×40mm flange size and only 0.34kg weight for easy integration into space-constrained designs.
D-Cut Shaft: Precision-machined flat shaft ensures reliable, backlash-free connection to pulleys, gears, or lead screws.
Class B (130°C) Insulation: High thermal resistance for reliable operation in demanding industrial environments.
Natural Cooling: Maintenance-free, fan-less design for quiet operation and reduced system complexity.
Robust Electrical Performance: Rated current of 0.9A and maximum current of 3.2A for stable, efficient power delivery.
HG-KR053D Materials & Applications
Materials
Frame & Flange: High-strength aluminum alloy with corrosion-resistant electro-coating for lightweight rigidity.
Shaft: Hardened, precision-ground alloy steel with D-cut flat finish for high wear resistance and torque transmission.
Stator: High-grade silicon steel laminations with Class B (130°C) insulated copper windings for efficient energy conversion.
Rotor: Permanent magnet (neodymium-iron-boron) for high magnetic flux density and stable torque output.
Encoder: Built-in 22-bit absolute optical encoder with sealed protective housing.
Connector: 4-pin rectangular industrial-grade power/signal connector for secure, vibration-resistant wiring.
Seals: Nitrile rubber (NBR) shaft seals for IP65 protection against dust and moisture.
Medical Devices: Laboratory automation, diagnostic equipment, and high-precision surgical robots.
Optical & Imaging Systems: Camera positioning, lens control, and precision scanning mechanisms.
Test & Measurement: High-speed data acquisition, dynamic test stands, and calibration equipment.
