摘要： A low-cost magnetic encoder that facilitates generating sinusoidal magnetic flux is provided. First and second permanent magnet arrays each include a plurality of permanent magnets arranged such that magnetic poles having the same polarity face each other, and magnetic yokes disposed on side surfaces of the plurality of permanent magnets. The permanent magnets and the magnetic yokes are arranged side by side at a predetermined pitch in the moving direction of a magnetic piece array. First and second magnetic detectors corresponding to the first and second permanent magnet arrays are disposed in a positional relationship allowing detection of leakage magnetic flux generated when the permanent magnet arrays and the magnetic piece array are displaced with respect to each other.

摘要： A rotational-linear motion converter includes a cylindrical magnet rotor, a linear rail, a teeth row, and a magnet row. The magnet rotor includes a magnet row magnetized in a radial direction of the magnet rotor. The rail includes a plurality of projecting portions and recessed portions. The teeth row includes teeth and allows a magnetic flux flowing from the magnet row of the magnet rotor to pass between the magnet rotor and the rail. The magnet row includes magnets and is magnetized in an extending direction of the rail in order to align the magnetic flux flowing from the magnet row of the magnet rotor toward the projecting portions and the recessed portions of the rail. In the magnet row magnetized in the extending direction of the rail, the same polarity faces of adjacent magnets oppose each other in the extending direction of the rail.
摘要翻译：旋转线性运动转换器包括圆柱形磁体转子，直线轨道，齿排和磁体排。磁体转子包括沿磁体转子的径向磁化的磁铁列。轨道包括多个突出部分和凹陷部分。齿排包括齿，并且允许从磁体转子的磁铁排流动的磁通在磁体转子和轨道之间通过。磁体列包括磁体，并且在轨道的延伸方向上被磁化，以便将从磁体转子的磁体列流动的磁通量朝向突出部分和轨道的凹陷部分对准。在沿轨道的延伸方向被磁化的磁铁列中，相邻磁体的相同极性面在轨道的延伸方向上彼此相对。
