The brushless linear rotary transformer has the advantages of simple and reliable structure, which can be applied to measure the angular displacement and the angular velocity in multiple turns. | ||||||

| 196 | Axial flux motor and generator assemblies | US13133325 | 2009-12-16 | US08922093B2 | 2014-12-30 | Timothy Richard Crocker |
| An axial flux motor assembly (10) comprises a stack of first and second discs (20a, 20b) arranged alternately such that there is a gap allowing rotation between each disc (20a, 20b). The first disc (20a) is mounted on a rotatable shaft (40), while the second disc (20b) is fixed in position. The first and second discs (20a, 20b) each comprise sectors (200) of magnetic material arranged on a face of the disc (20a, 20b), between each of which sectors (200) is a radially-extending conductor (202) of a conductive path (201) for conducting electric current. The sectors (200) of magnetic material on the first and second discs (20a, 20b) are arranged at a constant angular pitch, but the pitch of the sectors of magnetic material on the first disc may or may not be the same as those on the second disc. When electric current flows in the conductors (202), magnetic flux runs perpendicular to the faces of the discs (20a, 20b) in axially-extending flux paths (220), such that, considering the first disc(s) independently of the second disc(s), the magnetic flux in one axially-extending flux path (220) runs in an opposite direction to that in the immediately-adjacent flux paths (220) on each side of it, and is returned by flux return portions (30) of magnetic material provided at each end of the assembly (10). The total flux is the super-position of the flux of the first disc(s) and the second disc(s). The assembly (10) further comprises switching circuitry (50) for reversing the direction of current flowing in the conductive path (201) in one of the first disc (20a) or the second disc (20b) in correspondence to rotation thereof relative to the other of the first disc or the second disc in such a way as to effect continuous rotation of the first disc. | ||||||

| A rotor is rotatable on an axis within a stator. The rotor and stator each have facing coupled magnetic fields formed by electric coils positioned to produce axial force and radial magnetic filed. Stacked laminations are positioned to extend along the length of the rotor axis and the planes of the laminations lie parallel to the axis. There are several lamination packs arranged around both the rotor and the stator so as to shape the inter-engaging magnetic fields for maximum coupling across the rotor/stator airgap with minimum eddy current losses in the laminations. In this way, electric power is transmitted across a rotating coupling without rubbing or other wear contact to provide a long life. | ||||||
