In this example there are three electromagnetic circuits

connected at a common point. Each electromagnetic

circuit is split in the center, thereby permitting the permanent

magnet rotor to move in the middle of the

induced magnetic field. Most BLDC motors have a

three-phase winding topology with star connection. A

motor with this topology is driven by energizing 2

phases at a time. The static alignment shown in

Figure 2, is that which would be realized by creating an

electric current flow from terminal A to B, noted as path

1 on the schematic in Figure
