This guide explores several HG-Series modules, including their specifications, performance parameters, and common features such as Rated Torque, Operating Voltage, Output Power Capacity, Protection Ratings, and Speed.

HG-JR534K
The HG-JR534K is a high-performance AC brushless rotary servo motor with a 500W (0.5kW) rated output and a 22-bit encoder for precise position control. It operates at a rated torque of 1.6 Nm and 3000 RPM speed with a 400V AC class power supply. The motor features an IP67 protection rating and a 90×90 mm flange mount with MS-type connectors. It includes an oil seal for extended durability and operates within 0°C to 40°C.

HG-KR053
This module is known for its precision, featuring a rated speed of 3000 RPM and a maximum speed of 6000 RPM with a 0.05kW rated power. It has a rated torque of 0.16 Nm and a max torque of 0.56 Nm. With a rated current of 0.9 A and max current of 3.2 A, it provides excellent power efficiency. It uses a 22-bit encoder (resolution: 4194304 pulses/rev) and is ideal for precision motion applications.

HG-SR102K
With a rated power of 1 kW and a torque of 4.7 Nm (max: 14.3 Nm), the HG-SR102K supports heavy-duty industrial applications. It operates at 2000 RPM rated and up to 3000 RPM max. Featuring a straight shaft, IP67 rating, and a 22-bit absolute/incremental encoder, it suits moisture-prone and dusty environments.

HG-MR43K
Rated for 0.4 kW output, this module offers 1.3 Nm max torque and 2.6 A output current at 3000 RPM. It comes with a keyway shaft, flange mount, and a 22-bit encoder. The HG-MR43K has an IP65 protection rating, making it durable for demanding environments.

HG-KR73B
This 0.75kW rotary servo motor features a straight shaft with electromagnetic brake, 22-bit encoder, and operates at 3000 RPM (max 6000 RPM). It uses 4.8 A rated current on a 200V AC power supply. With a 2.4 Nm rated torque and 1.37 kg.cm^2 inertia, it supports dynamic control tasks.

HG-MR23
The HG-MR23 is a compact, high-precision servo motor rated at 0.2 kW. It delivers 0.64 Nm rated torque and 1.9 Nm max torque at a speed of 3000 RPM (max 6000 RPM). With 0.0865 kg.cm^2 inertia and a straight shaft, it is protected by an IP65 rating and suited for limited space installations.

Common Features of the Mitsubishi HG-Series

Optimal Temperature: Operates between 0°C and +40°C across all modules (e.g., HG-MR43K, HG-KR73B, HG-SR102K), ideal for standard industrial environments.

Operating Voltage: Most motors operate at 200V AC, standard for industrial applications (e.g., HG-JR534K, HG-KR13B, HG-SR102BK).

Rated Speed: Typically 3000 RPM, balancing performance, torque, and efficiency (e.g., HG-KR23B, HG-KR43B, HG-KR73, HG-SR102).

Torque: Ranges from 2.4 Nm to 8.4 Nm depending on application needs. Offers both nominal and max torque ratings for varied load requirements (e.g., HG-KR13B, HG-MR43K).

Protection Class: Modules are either IP65 or IP67 rated. IP65 modules like HG-MR43K and HG-KR053 are dustproof and water-resistant. IP67 modules like HG-JR534K and HG-SR102 offer enhanced protection.

Output Power Capacity: Ranges between 0.5kW and 0.75kW across modules (e.g., HG-KR13, HG-JR534K, HG-SR102), balancing power and energy efficiency.

Conclusion

The Mitsubishi HG-Series stands out for combining precise control, power efficiency, and durable design across its servo motor range.
