Yutaka Saito is a notable inventor based in Takatsuki, Japan. He is recognized for his innovative contributions to the field of miniature motors. His work has led to the development of a unique coreless motor design that showcases his engineering prowess.

Latest Patents

Saito holds a patent for a coreless motor, which features a miniature design where the coil of the rotor is wound in a hollow cylindrical shape. This rotor is rotatable within an air gap between a cylindrical permanent magnet and a cup-shaped yoke. The yoke is designed with pole-pitch zones of alternate polarity. The winding is progressively wound to create axially re-entrant bends, forming an inner and outer layer of wire. Each convolution of the winding is angularly related, allowing it to pass through pole-pitch zones of different polarity. The construction results in a thin cylindrical two-ply design, with one end edge having insulation removed to expose a conductive surface. This innovative design is complemented by a pair of brushes made from resilient spring metal, which provide localized axial contact with the exposed conductive surfaces.
