When is it "necessary" to choose a 1-phase 220V Servo Drive?
In the early stages of a project, if you meet any three or more of the following criteria, a 1-phase 220V Servo Drive is often the optimal solution, not a compromise:
- Only 220V single-phase power is available on-site.
- Equipment power is concentrated in the low to medium power range.
- Control cabinet space is limited, requiring a compact solution.
- OEM equipment, emphasizing cost control and batch consistency.
- Export equipment, requiring compatibility with overseas common power environments.
- Do not want to introduce three-phase power distribution, transformers, or additional approvals.
Procurement Decision Comparison: 1 Phase 220V vs 3 Phase 380V Servo Drive
| Decision-making dimensions | 1 Phase 220V Servo Drive | 3 Phase 380V Servo Drive |
|---|---|---|
| Power supply conditions | Single-phase 220V sufficient | Three-phase 380V required |
| Project start-up costs | Low power (no power distribution modification required) | Higher |
| Power compatibility | Small to medium power | Medium-high / High power |
| Control cabinet size | Smaller and more compact | Larger |
| OEM friendliness | Very high power | Medium |
| Multi-axis expansion | Feasible (bus support) | More advantageous |
| Typical applications | Standalone device / Modular system | Production line / Heavy-duty equipment |
| Procurement decision cycle | Short | Longer |
