The Design of a Permanent Magnet Motor for a Direct Drive Fan Application

By Lowell Christensen, Consultant | Lowell Christensen LLC

In this case study we will compare two types of permanent magnet brushless motors for a medium size overhead fan used in agricultural types of applications. The comparison will be done on the magnetic circuit portion of the motors only so the only volumes and weights compared will be the magnetic circuit parts including the magnet, back iron, lamination and copper wire.
