Radial flux permanent magnet electric motor​

A question that arises, in the search for the best fitting electric motor Is the choice between a radial flux or axial flux motor. Flux refers to the magnetic flux in electric motors. ‘Radial’ or ‘axial’ originates from the direction in which the permanent magnets impose the magnetic field.

A critical difference between the radial and axial flux electric motor is the amount of permanent magnet material that is used for a given performance.

An axial flux motor generally has a higher torque density than a radial flux motor however the axial flux motor generally uses significantly more permanent magnet material.

Another difference between the axial and radial flux motor is manufacturability and ease of construction. The radial flux motor benefits from a far more straightforward construction. This translates into an easier installation and a benefit in cost when it comes to the mechanical construction.

When considering the integration of a radial flux permanent magnet motor in your application be aware of your working conditions. As these will determine your torque and speed requirements, cooling principle and choice of the drive.
