20kW Axial Flux Direct Drive Permanent Magnet Generator 380V 200rpm Low Speed

20kW Axial Flux Direct Drive Permanent Magnet Generator 380V 200rpm Low Speed

This 20kW axial flux direct drive permanent magnet generator uses a pancake style rotor to deliver high torque at just 200rpm without a gearbox. The gearless construction removes mechanical loss and wear, making this permanent magnetic generator the reliable heart of small wind turbines and low-head hydro systems.

Key Features

• Axial flux pancake design delivers high torque density in a short axial length
• Direct drive gearless operation at 200rpm low speed with no gearbox loss
• NdFeB neodymium magnets for stable generation from variable renewable input
• 96% efficiency across the operating speed range
• IP54 protection for outdoor turbine and generator house installation

Technical Specifications

Structure & Design

Rotor and stator assemblies are manufactured with CNC precision and balanced to low vibration grades. The generator housing is available in foot-mounted or flange-mounted versions to match the turbine or engine drivetrain.

Applications

Designed for 5-25kW small wind turbines, low-head hydro turbines and tidal current generators where low speed direct drive generation is required.

Quality & Warranty

CE and ISO9001 certified with full factory test report and 3-year warranty. OEM/ODM customization is available for voltage, frequency, speed and shaft dimensions.
