Mitsubishi Electric HG-JR3534 Servomotor for Dynamic and Demanding Applications

Mitsubishi Electric HG-JR3534: Engineered for High-Performance Automation and Precision Control

In the demanding world of industrial automation, where precision, reliability, and dynamic performance are paramount, the selection of core components like servo motors directly dictates the efficiency and capability of the entire system. Mitsubishi Electric, a global leader in industrial automation and control systems, addresses these high-stakes requirements with the HG-JR3534, a low-inertia, medium-to-large capacity servomotor. This model is engineered to deliver a powerful and highly responsive motion solution, making it an ideal choice for a wide array of high-performance machinery. As a key component of the sophisticated MELSERVO-J4 series ecosystem, the HG-JR3534 is designed for applications that demand robust power, exceptional control fidelity, and the ability to perform high-frequency operations seamlessly.

The HG-JR3534 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, and automated assembly robots. In these environments, the motor's ability to deliver rapid acceleration and deceleration, maintain precise positioning, and provide consistent torque is critical for shortening cycle times, enhancing throughput, and maximizing overall equipment effectiveness (OEE).

Core Design and Operational Philosophy: Low Inertia for Superior Dynamics

The "low inertia" characteristic of the HG-JR3534'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.

• Minimized Settling Time: The HG-JR3534 can reach its target position more quickly and with minimal overshoot or vibration, leading to faster completion of critical move-and-stop cycles and contributing to higher production speeds.

• 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, leading to increased machine longevity and lower long-term maintenance costs.

Exceptional Performance and Robust Construction

The HG-JR3534 is built to deliver consistent, powerful performance in 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. Furthermore, the model is designed without a built-in electromagnetic brake (as indicated by the model number suffix), which is a configuration aimed at applications where external braking is used or where holding torque is not a critical requirement

.

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.

Precision Control through High-Resolution Feedback

At the heart of the servomotor's precision is its high-resolution absolute encoder. The HG-JR3534 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-JR3534 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.

• Support for Multiple Control Modes: The system supports position control, speed control, and torque control, offering flexibility for complex applications

• .

Energy Efficiency and Operational Reliability

In an era focused on sustainable and cost-effective manufacturing, the HG-JR3534 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.
