Absolute position information of electric motors or rotating mechanical parts used in some
industrial applications is critical. This information can be measured either digitally using an …

Resolvers as position sensors need a high frequency AC excitation voltage, and the induced
voltage in their 2-phase perpendicular windings are amplitude modulated (AM) signals. For …

Axial flux variable reluctance (AFVR) resolvers have substantial benefits that make them
suitable for motion control drives. However, they suffer from insufficient accuracy, especially …

Among position sensors, resolvers are superior from reliability point of view. However,
obtaining lower output voltage harmonics and simple manufacturing process is a challenge …

Linear variable reluctance (LVR) resolvers have substantial benefits that make them suitable
for linear motion control drives. The optimal design of LVR resolvers needs an accurate …

The stator-PM machine concept has been practiced on the recently proposed stator-PM
