Buying Guide
What to consider when choosing a 380V three-phase generator
Voltage compatibility, output power, and efficiency are primary factors. Ensure the generator’s three-phase output aligns with your load requirements and that the device can operate at your typical rotor speeds if used with wind or hydro setups.
- Voltage and phase: Confirm 380V three-phase output and any dual-voltage capability (e.g., 220V/380V) for versatility.
- Speed and torque: Low-speed PMGs are ideal for turbine-driven systems but require proper matching to rotor speed and load.
- Construction and durability: Die-cast housings, corrosion resistance, and bearing quality influence longevity in harsh environments.
- Control interface: Some models include DC drive motors, precision couplings, or VFD options for speed control and testing accuracy.
- Maintenance and ease of use: Look for gearless designs with straightforward operation and minimal maintenance requirements.
How to compare models clearly
Use side-by-side checks on power rating, voltage range, start-up torque, and the intended application. If you plan wind or water turbine use, prioritize low-speed designs with robust mechanical construction. For lab testing or QA, a dedicated test bench PMG with a dependable DC drive system can provide repeatable results.
