AFPM Generator Technology and How it Works

Where traditional Radial Flux Permanent Magnets (RFPM) orient the magnetic flux outward from the shaft of the turbine, the Axial Flux Permanent Magnet (AFPM) technology works by orienting the magnetic flux along the axis of the turbine shaft.

In our AFPM generators, a coil is wrapped around a specially designed disc at the centre axis. Magnetic discs then rotate on the sides of the coiled disc and generate electricity, consistent with Faraday\'s Law. This kind of power generating technology is therefore ideal for wind power generation because its initial operation torque (cut-in speed) is lower than the current Radial Flux Permanent Magnet (RFPM) method.

AFPM power generation is classified into two configurations, the inner type and outer type. In the inner type configuration, only the magnetic disk rotates while the generator housing remains fixed. In the outer type configuration, the whole generator body rotates by fixing the magnetic disk to the body.
