🤝 Strengthening global partnerships through trust and performance!

We were pleased to welcome our long-term strategic partner from Malaysia to our facility, where they reviewed the testing process of their ordered Permanent Magnet Generators (PMGs). ⚙️

During the visit, our engineering team demonstrated:
✔ Full load performance testing
✔ Insulation & voltage withstand verification
✔ System matching with wind power configurations

Impressed by the stability and quality of our PMGs, the customer confirmed a follow-up order on-site and officially signed a long-term cooperation agreement with us. 🌍

Same 3kw Big Different
Wind turbines have different rated wind speeds, and blade size is the decisive factor in determining a turbine’s power output.

Direct-drive permanent magnet generator (3-phase AC PM), with wind rotor directly driving the generator – no gearbox. Wind pressure automatic yaw protection + electromagnetic brake protection ensure safety in high winds.

🟢Key Advantages

Low start‑up & wide range : 3m/s start, 4-25m/s working, withstands 50m/s

High output : Up to 4,095 kWh/year /s

Durable & weather‑resistant : IP54, -25℃ to 55℃, fiberglass blades

Flexible voltage : DC48V – DC380V options
