Description
The Mitsubishi HG46 is a model from the HG series AC servo motors, but unlike HG54, HG75, HG104, etc., it is an older / less common variant designation used in early Mitsubishi CNC servo systems and documentation.
š§ HG46 Servo Motor Overview
- Series: Mitsubishi HG AC servo motor family
- Type: Low-power feed-axis servo motor
- Typical class: ~0.4 kW range (approx.) depending on system generation
- Use case: Light CNC feed axes (small X/Y positioning, tool movement, auxiliary axes)
āļø General Characteristics
While exact values can vary depending on the CNC generation (MDS-E / older controllers), HG46 motors generally share:
- Compact frame size (smaller than HG54)
- Low inertia rotor for fast response
- High-resolution encoder (for CNC positioning feedback)
- 200V AC servo system compatibility
- Designed for precision rather than torque-heavy cutting loads
š Typical Applications
- Small CNC machine feed axes
- Tool changers / auxiliary mechanisms
- Lightweight positioning systems
- Older Mitsubishi CNC machining centers
š Important Note (very important in practice)
HG46 is not part of the commonly used modern HG naming sequence like:
HG54 ā HG75 ā HG104 ā HG154 ā HG204 ā HG224 ā HG354
So in real maintenance situations:
- HG46 is often legacy / discontinued equivalent class
- It is usually replaced by HG54 or nearest compatible motor, depending on torque and mounting
š Simple Meaning
HG46 =
Early-generation Mitsubishi HG-series low-power servo motor used for light CNC axis control (legacy class, roughly around 0.4 kW range).
