Description
The Mitsubishi HG354 is a model from the HG series AC servo motor family, used in CNC systems such as MDS-E / MDS-EM / MDS-EJ drive units.
🔧 HG354 Servo Motor Overview
- Series: Mitsubishi HG AC servo motor family
- Type: High-power CNC feed-axis servo motor
- Power class: ~3.5 kW
- Use case: Heavy-duty CNC motion (large cutting loads, high inertia axes)
⚙️ Key Technical Characteristics
Typical HG354 specifications:
- Rated output: 3.5 kW
- Rated torque: ~11.1 N·m
- Stall torque: ~22 N·m (approx.)
- Maximum torque: ~57 N·m
- Rated speed: 3000 rpm
- Voltage: 200V AC
- Encoder: High-resolution absolute encoder (CNC feedback system)
- Protection: IP67
- Large frame size (heavy-duty motor body)
- Designed for high rigidity + high torque + high inertia loads
🏭 Typical Applications
- Large CNC machining centers
- Heavy milling machines
- High-load X/Y/Z feed axes
- Turning centers with strong cutting forces
- Industrial automation with large inertia systems
📊 Position in HG family
HG354 is the top-end standard HG motor class:
- Stronger than HG204 / HG224 / HG154 / HG104 / HG75 / HG54
- Used when maximum torque and rigidity are required
- Typically paired with higher-capacity MDS-E / EM drives (160-class systems)
📌 Simple Meaning
HG354 =
Mitsubishi HG-series 3.5 kW AC servo motor used for heavy-duty CNC feed-axis control with very high torque and rigidity.
