The Mitsubishi AC servo motor HG-SR702B belongs to the MELSERVO-J4 HG-SR series, designed for medium-inertia applications requiring accurate positioning and stable torque performance.
This 7kW servo motor is suitable for CNC machines, injection molding equipment, robotics systems, conveyors, and heavy-duty automation equipment.
Key specifications include:
The integrated absolute encoder provides accurate feedback without battery backup, supporting stable positioning and improved machine performance.
Industrial automation systems require motors that can maintain accuracy under continuous operation. The Mitsubishi HG-SR702B delivers several advantages for high-performance motion applications.
With 33.4 Nm continuous torque and 100 Nm peak torque, this Mitsubishi servo motor supports demanding mechanical loads.
Typical applications include:
The IP67-rated housing protects the motor from dust and water exposure, making it suitable for industrial environments where reliability is essential.
The straight shaft with brake design also helps maintain position stability when equipment stops or requires vertical-axis control.
The HG-SR702B works with Mitsubishi MR-J4 servo amplifiers, providing functions such as:
This compatibility allows you to upgrade or replace existing Mitsubishi motion systems without major modifications.
