Mitsubishi Electric HG-SR301J HG-SR Series AC Servo Motor

Description

Designed for high-inertia motion control applications, the HG-SR301J is a medium-capacity industrial AC servo motor manufactured by Mitsubishi Electric as part of the HG-SR Series. Operating with a rated output power of 3.0 kW and a nominal rotation speed of 1000 r/min, this motor provides reliable torque control and high positioning accuracy when paired with compatible MELSERVO servo amplifiers.

The HG-SR301J is equipped with an integrated oil seal (designated by the "J" suffix) to safeguard internal components from fluid entry in demanding industrial environments. Built with a robust physical architecture, it is engineered to withstand substantial mechanical stress, featuring specified vibration resistance along multiple axes to maintain performance stability during continuous high-load cycles.

Features

• 3.0 kW rated output power suitable for heavy-load industrial machinery.
• Rated rotation speed of 1000 r/min optimized for high-torque, low-speed applications.
• Integrated shaft oil seal provides protective sealing against oil and industrial fluids.
• Rugged environmental tolerance, with vibration resistance rated up to 24.5 m/s2 in the X-axis and 29.4 m/s2 in the Y-axis.
• Natural cooling system design suitable for closed cabinet integration.

Applications

• Automated material handling and heavy-load conveyor systems.
• Metal forming, bending, and cutting machinery.
• Industrial printing, binding, and packaging systems.
• Multi-axis gantry robots and heavy positioning stages.

Installation Guidelines

Prior to mounting, ensure the installation area is clean, dry, and free from corrosive gases or excessive oil mist. The motor must be secured to a rigid mounting base to prevent operational resonance and misalignment with the load. For models configured with an oil seal, inspect the shaft sealing surface regularly and apply suitable lubricant as required by standard maintenance schedules.

When routing power and encoder cables, maintain the specified bending radius and avoid putting excessive tension on the connectors. Ensure the motor frame is grounded according to local electrical codes to prevent electrical noise interference with the drive amplifier feedback loop.
