The difference between axial flux permanent magnet machine and radial flux one

[madeza]

hi electrical partners...
what´s the difference between an axial flux permanent magnet machine AFPM (disc type rotor) and a radial flux permanent machine (cylindrical rotor)

thanks

Re: the diference

Hi,

In one case the magnet axes (N/S) are oriented towards the stator, and in the other case they are perpendicular. I think that the latter is more common in motors designed for high speed operation (combined with reluctance torque), and the former for low speed/high torque.

Re: the diference

Hi Friend,


In Axial Flux motors, the flux is produced axially along the axis of the rotor as the name indicates.

In Radial Flux motors, the flux is produced radially along the sideways of the rotor as the name indicates.
