STATOR

The stator for a brushless DC motor is a laminated steel core with coils of magnet wire embedded and connected in one, two or more phases so that by sequentially exciting these phase winding, a rotating electromagnetic field can be generated. Since both iron and copper losses in the brushless DC motor take place in the stator, generated heat is easily transferred to the surroundings. A motor with an inner rotor is better in this regard due to the larger stator area in contact with the mounting surfaces.

ROTORS

In all continuous rotation brushless DC motors, the permanent magnetic field is on the rotor. The windings supplying the rotating electromagnetic field are in the stator. The rotor can be designed inside of the stator, as in a conventional motor, or outside of the stator. The inner rotor design is generally used in incremental motion application where low inertia and fast response are required. The outer rotor configuration provides a more rigid structure for the permanent magnets and has higher inertia. It is used in high speed applications where a stiff structure is required to counter the centrifugal forces acting on the permanent magnets, in velocity loop applications where the additional rotor inertia is desired for velocity stabilization, or when the additional inertia is insignificant relative to the total inertia as in a memory disk drive.
