摘要： A rotor (68) includes a circular rotor core (66), a plurality of θ magnets (28), and ring-shaped Z magnets (60). The rotor core (66) has a plurality of magnet holding sections formed radially with a rotating shaft as the center.

摘要： Ein linearer Schrittmotor dient zur Verschiebung eines Läufers parallel zu einem Stator mit N Schritten. Der Stator hat (N+2) Statorpolschuhe die von einem Rückschlußelement umschlossen und jeweils gleich weit von benachbarten Statorpolschuhen entfernt sind. Weiterhin ist mindestens eine Spule zwischen zwei Statorpolschuhen angeordnet. Der Läufer wird vom Stator umschlossen und hat einen parallel zum Stator magnetisierten Permanentmagneten, der zwischen zwei Läuferpolschuhen angeordnet ist. Der Läufer nimmt innerhalb des Stators durch die Reluktanzkräfte stabile Ruhepositionen ein, bei denen die Statorpolschuhe den Läuferpolschuhen gegenüber liegen. Durch Bestromung der Spulen mit einem kurzen Stromimpuls kann der Läufer innerhalb des Stators zwischen den verschiedenen stabilen Ruhepositionen verschoben werden.

摘要： 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), whilst 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.
摘要翻译：轴向通量电动机组件（10）包括交替布置的第一和第二盘（20a，20b）的堆叠，使得存在允许每个盘（20a，20b）之间旋转的间隙。第一盘（20a）安装在可旋转的轴（40）上，而第二盘（20b）固定就位。第一和第二盘（20a，20b）各自包括布置在盘（20a，20b）的表面上的磁性材料的扇区（200），在每个扇区（200）之间的是径向延伸的导体（202），传导电流的导电路径（201）。第一和第二盘（20a，20b）上的磁性材料的扇区（200）以恒定的角度间距排列，但第一盘上的磁性材料扇区的节距可以与第一盘上的磁性材料扇区的节距相同或不同第二张碟片。当电流在导体（202）中流动时，磁通在轴向延伸的磁通路径（220）中垂直于磁盘（20a，20b）的面延伸，使得考虑第一磁盘独立于第二磁盘在一个轴向延伸的磁通路径（220）中的磁通量沿与其每一侧上紧邻的磁通路径（220）中的磁通量方向相反的方向延伸，并且由磁通返回部分（30 ）设置在组件（10）的每个端部处的磁性材料。总通量是第一盘（一个或多个）和第二盘（一个或多个）的通量的超位置。该组件（10）还包括开关电路（50），该开关电路用于使在第一盘（20a）或第二盘（20b）中的一个中的导电路径（201）中流动的电流的方向相应于其旋转相对于第一盘或第二盘中的另一个以这种方式实现第一盘的连续旋转。

摘要： A movable member is moved in a preset direction in a linear motor. Acharacteristic-changeposition-detecting unit detects a position where the magnetic characteristic of the magnets has abruptly changed. The position detected is used as an origin-setting reference position. A reference position for the absolute position of the magnetic linear encoder is set based on the reference position.
