Mitsubishi M80 Tool Spindle Motor HG-JR153

🔧 Mitsubishi HG-JR153 – Description

The HG-JR153 is a Mitsubishi Electric HG-JR Series AC servo motor used in CNC machine tool feed axes and industrial automation systems. It is a medium-capacity, low-inertia rotary servo motor designed for high-speed positioning, fast acceleration, and precise motion control.

It is commonly used for ball screw driven CNC axes (X, Y, Z) rather than spindle rotation.

• Shaft type: Straight shaft (standard coupling use)
• Cooling: Natural / fan-assisted depending on variant

⚙️ Functional Characteristics

• Designed for high-frequency start/stop motion
• Optimized for:
  • Fast acceleration/deceleration
  • Smooth low-speed control
  • High-precision positioning
• Works with Mitsubishi MR-J4 servo amplifiers

🏭 Typical Applications

The HG-JR153 is widely used in:

• CNC machining center feed axes (X/Y/Z)
• High-speed automation equipment
• Packaging and assembly machines
• Pick-and-place systems
• Industrial robotics (light–medium load)

⚠️ Important Note

• ❌ Not a spindle motor (SJ series is for spindles)
• ❌ Not a linear motor (LM series is for direct-drive axes)
• ✅ It is a rotary axis servo motor for precise motion control

⚡ Summary

The HG-JR153 is:

• A 1.5 kW CNC servo motor
• Medium-power, low-inertia high-speed axis motor
• Equipped with a high-resolution 22-bit encoder
• Designed for fast and precise machine axis movement
