Mitsubishi Electric HG-JR2034B 400V Servo Motor for High-Frequency and High-Acceleration Applications

Mitsubishi Electric HG-JR2034B: Engineering Excellence for High-Performance Automation

In the competitive landscape of industrial automation, the demand for servo motors that deliver a perfect synergy of power, precision, and reliability is ever-increasing. Mitsubishi Electric, a global leader in automation technology, meets this challenge with the HG-JR2034B, a low-inertia, medium-capacity servomotor engineered to excel in the most demanding high-frequency and high-acceleration applications. This model is not merely a component; it is a sophisticated motion solution designed to empower a wide array of industrial machinery with its robust performance and advanced features. As a key component of the high-performance MELSERVO-J4 series ecosystem, the HG-JR2034B is crafted for applications where rapid cycling, precise positioning, and consistent operation under strenuous conditions are paramount

.

The HG-JR2034B is particularly suited for dynamic applications such as high-speed packaging machinery, advanced assembly robots, precision printing presses, and automated material handling systems

. Its design philosophy centers on providing the mechanical power and control fidelity necessary to shorten cycle times, enhance throughput, and maximize overall equipment effectiveness (OEE), thereby offering a significant return on investment for machine builders and end-users alike.

Core Design and Operational Philosophy: Low Inertia for Superior Dynamics

The "low inertia" characteristic of the HG-JR2034B's rotor is fundamental to its exceptional performance profile. A low-inertia rotor possesses minimal resistance to changes in rotational speed, allowing it to accelerate and decelerate with remarkable agility

. This design principle yields significant operational advantages that are critical in modern manufacturing:

• Minimized Settling Time: The motor can reach its target position more quickly and with minimal overshoot or vibration, leading to faster completion of critical move-and-stop cycles. This directly contributes to higher production speeds and improved product quality.

• Optimized Cycle Times: The ability to perform rapid acceleration and deceleration translates directly into a higher number of operational cycles per minute, boosting machine throughput and productivity.

• Reduced Load on the Servo Amplifier: The lower torque requirement for acceleration allows for optimal synergy with its matched MR-J4 series servo amplifier, ensuring a stable, efficient, and responsive system

• .

Exceptional Performance and Robust Construction

The HG-JR2034B is built to deliver consistent, powerful performance. With a rated output of 2.0 kW and a rated speed of 3000 rpm, it offers a robust foundation for various high-demand drive tasks

. Its torque capabilities are a standout feature, with a rated torque of 6.37 Nm and a maximum instantaneous torque that soars to an impressive 19.1 Nm. This high peak torque provides a substantial reserve for overcoming instantaneous load shocks, driving through momentary resistance, or handling sudden changes in material density without losing positional accuracy or stalling.

Durability in harsh industrial environments is a key design consideration. The motor boasts a high IP67 protection rating

. This signifies that it is completely dust-tight and can withstand immersion in water up to 1 meter for 30 minutes. This makes it exceptionally suitable for applications that require frequent washdowns with high-pressure jets, such as in food and beverage, pharmaceutical, and chemical manufacturing. Furthermore, the model is equipped with a built-in electromagnetic brake

, a critical safety and holding feature for vertical axes or applications requiring secure stopping to prevent unintended movement, enhancing both operational safety and machine reliability.

Precision Control through High-Resolution Feedback

At the heart of the servomotor's precision is its high-resolution absolute encoder. The HG-JR2034B incorporates a 17-bit absolute encoder with a resolution of 131,072 pulses per revolution

. This exceptionally fine feedback allows the accompanying MR-J4 servo amplifier to exercise extremely precise control over the motor's position, velocity, and torque. The result is exceptionally smooth rotation even at very low speeds, elimination of cogging, and unparalleled positioning accuracy. This level of precision is vital for sensitive applications like precision machining, electronic component assembly, and high-quality printing.

Seamless System Integration and Advanced Intelligence

A standout feature of the HG-JR2034B is its role within the broader, intelligent MELSERVO-J4 system. When paired with an MR-J4 series servo amplifier, it forms a networked motion control solution that is greater than the sum of its parts

. This system supports a wide array of industry-standard field networks, including CC-Link IE Field, PROFINET, EtherCAT, and EtherNet/IP, ensuring easy and flexible integration into virtually any factory automation environment.

The system also incorporates advanced, intelligent functions that simplify setup and autonomously optimize performance:

• Advanced Vibration Suppression Control II: This sophisticated feature automatically identifies the frequency of machine vibration and applies intelligent filters to suppress it

• . This is crucial for systems with long arms or flexible components, as it drastically reduces settling time, improves positioning accuracy, and prevents mechanical wear.

• One-Touch Tuning: This function greatly simplifies the commissioning process by allowing the servo amplifier to automatically configure the optimal gain parameters for the connected mechanical system

• . This significantly reduces setup time and lowers the requirement for expert servo tuning knowledge, making high performance more accessible.

• Real-Time Autotuning: The system continuously monitors the load condition and dynamically adjusts the servo gains in real-time to maintain optimal performance, ensuring consistent and stable operation even as machine characteristics change over time due to wear or varying payloads

• .

Energy Efficiency and Operational Reliability

In an era focused on sustainable and cost-effective manufacturing, the HG-JR2034B addresses energy efficiency through its high-performance electromagnetic design. This design minimizes electrical losses and converts more input power into useful mechanical work

. This not only reduces operational electricity costs but also lowers thermal stress on the motor windings and components, contributing to its long-term reliability and service life. The use of an absolute encoder eliminates the need for backup batteries to maintain positional data after a power cycle, simplifying maintenance, reducing lifetime costs, and removing a potential point of failure.
