Mitsubishi HG-SR702J 7kW Brushless Servo Motor IP67

Mitsubishi HG-SR702J Brushless Servo Motor for Medium-Capacity Tasks

Product Introduction

The Mitsubishi HG-SR702J comes from the reliable HG Series and handles medium-capacity applications with ease. This brushless servo motor delivers 7 kW output power, making it suitable for demanding industrial tasks. Additionally, its medium inertia design provides a perfect balance between fast response and stable load handling. You can use this motor in environments where dust or water exposure is a concern.

Technical Specifications

The Mitsubishi HG-SR702J operates on a 200VAC power class. Its rated speed is 2000 rpm, while the maximum speed reaches 3000 rpm. For torque delivery, this model provides consistent performance across its speed range.

• Rated Current: 26A

• Maximum Current: 83A

• Encoder Type: 22-Bit Absolute Encoder

• Inertia Level: Medium Inertia

• Oil Seal: Included

• IP Rating: IP67

• Motor Type: Brushless

Furthermore, the 22-bit absolute encoder gives you detailed position feedback. Specifically, this encoder improves accuracy during complex motion sequences. Therefore, the HG-SR702J suits applications like CNC machines and robotic arms.

Environmental and Protection Features

This servo motor includes an IP67 protection rating. As a result, it resists dust ingress and withstands temporary water immersion. Moreover, the unit comes with an oil seal, which adds extra protection against lubricants in industrial settings.

The operating temperature range is 0 to 40 degrees Celsius. For storage, you can keep the motor safely between -15 to 70 degrees Celsius. These parameters make the Mitsubishi HG-SR702J reliable in workshops and factory floors.

Installation Guidelines

First, mount the Mitsubishi HG-SR702J on a rigid base to avoid vibrations. Next, connect the power cables according to the 26A rated current. Use appropriate gauge wires for peak loads up to 83A. Then, wire the 22-bit absolute encoder to your controller for precise feedback. For instance, shield the encoder cables to prevent electrical noise interference.

Additionally, ensure the motor has enough airflow around it. Although the IP67 rating allows some exposure, keeping the unit dry extends its service life. Finally, test the motor at 2000 rpm before increasing to maximum speed.

Frequently Asked Questions (FAQ)

1. Can the HG-SR702J operate in a washdown environment?
Yes, its IP67 rating allows temporary water exposure, but avoid high-pressure jets directly at the seals.

2. Is the 22-bit encoder compatible with all Mitsubishi drivers?
The encoder works best with Mitsubishi's J4 and J5 series drivers. Check your driver's manual for absolute encoder support.

3. What happens if the motor exceeds 40 degrees Celsius?
The HG-SR702J may reduce output power or trigger thermal shutdown. Always keep the operating temperature within 0 to 40°C.

4. Why does this model include an oil seal?
The oil seal prevents lubricant from entering the motor housing. This feature is essential for gearbox-coupled applications.

5. Can I use this motor without a brake?
Yes, the Mitsubishi HG-SR702J does not have a built-in brake. For holding applications, add an external brake unit.
