Axial and Radial flux permanent magnet machines – What is the difference?

Electrical machines can be classified into two categories - radial and axial flux machines. Radial flux machines are more common and are in use for long time. Though axial flux machines are not that new, their use has been increased only during the past two decades. The difference as their names imply is that in axial flux the magnetic flux direction is parallel to the machine rotation axis whereas in radial flux machines, the magnetic flux direction is radial.
