Key features

The ironless stator design eliminates cogging torque, allowing the generator to start easily at low rotational speeds and maximize energy capture from weak wind conditions.

Without iron-core hysteresis and eddy current losses, the generator delivers high power conversion efficiency, making it ideal for renewable energy applications.

Equipped with high-performance rare earth permanent magnets and a multi-pole rotor, the generator provides high power density and stable electrical output.

Designed for direct-drive systems without a gearbox, reducing mechanical losses while improving overall reliability and operating efficiency.

The brushless construction minimizes wear parts, reducing maintenance costs and ensuring long service life.

The coreless structure minimizes vibration and torque ripple, resulting in quieter operation suitable for residential and commercial environments.

The axial flux structure offers an excellent power-to-weight ratio, making installation easier while saving installation space.

The ironless design reduces heat generation during operation, improving efficiency and extending component lifespan.

Available from 0.5kW to 50kW with customizable voltage, speed, shaft configuration and mounting dimensions for different renewable energy systems.

Suitable for vertical axis wind turbines, horizontal wind turbines, hydro generators, diesel hybrid systems, and other low-speed renewable energy projects.

Product Q&A

Q:What are the advantages of a coreless axial flux generator?

The coreless design reduces cogging torque, improves startup performance, minimizes iron losses, and delivers higher efficiency at low rotational speeds.

Q:Why is a low start torque important?

Lower start torque allows the wind turbine to begin rotating in lighter winds, increasing annual energy generation and improving overall system performance.

Q:Is this generator suitable for direct-drive wind turbines?

Yes. It is compatible with both vertical-axis (VAWT) and horizontal-axis (HAWT) wind turbines, especially low-speed renewable energy applications.

Q:What voltage options are available?

We offer customized voltage options based on customer requirements, including 24V, 48V, 96V, 120V, 220V, and 380V.

Q:Is OEM or ODM service available?

Yes. We support OEM and ODM services, including customized logos, dimensions, shaft types, flange designs, winding specifications, and packaging.
