Mitsubishi Electric HG-JR3534B: Precision Engineered for High-Performance Industrial Automation

In the rapidly evolving landscape of industrial automation, the demand for servo motors that deliver an optimal balance of power, precision, and reliability has never been greater. Mitsubishi Electric, a globally recognized leader in automation technology, addresses these demanding requirements with the HG-JR3534B, a low-inertia, medium-capacity servomotor engineered to excel in 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, integrated safety features, and exceptional durability. As an integral part of the high-performance MELSERVO-J4 series ecosystem, the HG-JR3534B is crafted for applications where rapid cycling, precise positioning, and consistent operation under strenuous conditions are paramount.

The HG-JR3534B is particularly suited for dynamic and demanding applications. Its performance characteristics make it an excellent fit for high-speed packaging machinery, advanced material handling systems, precision printing presses, automated assembly robots, and food processing equipment

. In these environments, the motor's ability to deliver rapid acceleration and deceleration, maintain precise positioning under variable loads, and provide consistent torque is critical for shortening cycle times, enhancing throughput, and maximizing overall equipment effectiveness (OEE). The inclusion of a built-in electromagnetic brake further enhances its suitability for applications involving vertical axes or where safe, secure stopping is a necessity

Core Design and Operational Philosophy: Low Inertia for Superior Dynamics

The "low inertia" characteristic of the HG-JR3534B's rotor is a fundamental aspect of its design philosophy. A low-inertia rotor possesses minimal resistance to changes in its rotational speed, allowing it to accelerate and decelerate with remarkable agility. This design principle yields significant operational advantages that are critical in modern manufacturing:

• Optimized Cycle Times: The motor's rapid acceleration and deceleration capabilities directly translate into a higher number of operational cycles per minute, significantly boosting machine throughput and productivity. This is essential for applications like pick-and-place robots and high-speed packaging lines.

• Minimized Settling Time: The HG-JR3534B can reach its target position more quickly and with minimal overshoot or vibration, leading to faster completion of critical move-and-stop cycles. This high responsiveness contributes to higher production speeds and improved product quality.

• Reduced Mechanical Stress: The swift and controlled movements help to reduce unnecessary dwell times and shuddering, which in turn minimizes wear and tear on the broader mechanical system, such as belts, gears, and linear guides. This leads to increased machine longevity and lower long-term maintenance costs.

Exceptional Performance and Robust Construction

The HG-JR3534B is built to deliver consistent, powerful performance in the most challenging industrial environments. With a rated output of 3.5 kW and a rated speed of 3000 rpm, it offers a robust foundation for various high-demand drive tasks

. This motor operates on a 400V power supply, making it suitable for industrial settings with higher voltage infrastructure, ensuring efficient power delivery and reduced current draw

.

Its torque capabilities are a standout feature, with a rated torque of 10.5 Nm and a maximum instantaneous torque that soars to an impressive 32 Nm

. This high peak torque, approximately 300% of the rated value, 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 is engineered into its core. 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, where moisture, dust, and corrosive cleaning agents are a constant challenge.

Furthermore, the model is equipped with a built-in electromagnetic brake

. This is a critical safety and holding feature for vertical axes or applications requiring secure stopping to prevent unintended movement in the event of a power loss, thereby 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-JR3534B incorporates a 17-bit absolute encoder with a resolution of 131,072 pulses per revolution

. This exceptionally fine feedback allows the accompanying MR-J4 series 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-JR3534B 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, 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-JR3534B 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.
