Mitsubishi HG-KR Servo Motor
The Mitsubishi HG-KR Servo Motor is the low-inertia, high-response permanent magnet synchronous servo motor designed as the standard pairing for the MR-J4 and MR-J5 servo amplifiers in high-speed positioning and high-cycle-rate applications. The HG-KR series covers 50 W to 7 kW and is characterised by a low rotor inertia ratio — typically 5× lower than medium-inertia equivalents — which produces the high servo bandwidth and fast settling time required by pick-and-place, high-speed packaging, and electronic assembly machine applications. The HG-KR73 (750 W) is the most widely deployed member of the HG-KR family, with a rated torque of 2.39 N·m, maximum speed of 6,000 rpm, and the 22-bit absolute encoder that is standard across the Mitsubishi MELSERVO HG motor range.
The HG-KR is designed for direct compatibility with MR-J4 and MR-J5 amplifiers using Mitsubishi's high-flex MR-JCCBL cable — a single hybrid cable carrying encoder feedback, motor power, and brake signals that eliminates the need for separate motor, encoder, and brake cables, reducing installation wiring cost by up to 40% in multi-axis machine cabinet builds. IP65 ingress protection rating (IP67 option for shaft seal) makes the HG-KR suitable for installation in the dusty and humid Saudi manufacturing environments found in food processing, cement packaging, and chemical production facilities. The motor's continuous operating temperature range of -20°C to +80°C ambient with Class F winding insulation ensures long service life in the extreme Saudi summer ambient conditions found in un-air-conditioned machine rooms.
The HG-KR is the standard servo motor specified alongside MR-J4 amplifiers in Saudi Arabia's precision manufacturing and packaging machine installations. Saudi pharmaceutical packaging machine builders under SFDA regulation specify HG-KR motors for blister pack forming, indexing, and sealing axes, where the absolute encoder eliminates reference-run requirements at machine restart after power loss — critical for GMP compliance. Vision 2030 industrial robot assembly cells in Saudi auto parts manufacturing facilities use HG-KR motors on robotic arm axes, where low inertia enables rapid acceleration/deceleration for short cycle-time assembly tasks. Ma'aden's aluminium fabrication machinery at Ras Al-Khair uses HG-KR drives on CNC forming centre axes.
Razz Middle East maintains stock of HG-KR motors from 50 W to 3 kW (including HG-KR13, HG-KR23, HG-KR43, HG-KR73, HG-KR153) and the matching MR-JCCBL hybrid cables in standard lengths (3 m, 5 m, 10 m) at our Riyadh warehouse. Motor sizing calculations, inertia analysis, and thermal derating studies for Saudi ambient conditions are provided free of charge with project quotation. SAR pricing for motor + amplifier + cable packages is available within 4 hours.

Key Features & Benefits
- Low rotor inertia (5× lower than medium-inertia series) delivers high servo bandwidth and fast settling time for pick-and-place, high-speed packaging, and assembly machine applications.
- 22-bit absolute encoder eliminates reference-run requirements at machine restart after power loss, meeting GMP compliance requirements in Saudi pharmaceutical facilities.
- IP65 rated enclosure (IP67 shaft seal option) protects against dust and moisture in Saudi food processing, cement, and chemical manufacturing environments.
- MR-JCCBL single hybrid cable combines motor power, encoder, and brake signals in one cable, reducing multi-axis machine cabinet wiring cost by up to 40%.
- Class F winding insulation with -20°C to +80°C operating range ensures long motor service life in un-air-conditioned Saudi machine rooms during summer peak ambient temperatures.
- Direct mechanical compatibility with MR-J4 and MR-J5 amplifiers via standard connector and cable interface simplifies axis replacement and maintenance on Saudi production floors.
Industrial Applications in Saudi Arabia
- Saudi pharmaceutical packaging blister pack forming, indexing, and sealing machine axes, where absolute encoder eliminates reference-run requirements for SFDA GMP compliance after power loss.
- High-speed pick-and-place robot arm axes in Saudi electronics assembly and Vision 2030 industrial robot cells, where low inertia enables short cycle time and high throughput.
- Precision CNC forming centre axes at Ma'aden aluminium fabrication facilities at Ras Al-Khair, where low inertia and high bandwidth deliver tight positional accuracy.
- Food portioning and weighing machine servo axes in Saudi FMCG factories, where IP65 protection enables washdown cleaning in food safety zone machine areas.
- Automated inspection and testing machine axes in Saudi quality assurance laboratories, where 22-bit encoder resolution provides sub-micron position feedback for measurement consistency.
