Latest Patents
One of Sekiguchi's latest patents is a Permanent Magnet Motor. This motor comprises a permanent magnet and an armature featuring multiple winding grooves that face the permanent magnet, separated by an air gap. The armature also includes auxiliary grooves on its magnetic pole surface, which generate cogging torque vectors that are strategically deviated from those produced by the winding grooves. This design enhances the efficiency and performance of the motor.
Another significant patent is an Absolute Encoder. This device features tracks arranged side-by-side on a magnetic drum, where absolute patterns of circulatory random sequence codes are recorded. An additional track generates sinewaves in synchronism with the reading of these absolute patterns, allowing for a precise combination of coarse and fine positional values. The encoder's design ensures that the magnetic resistive elements are connected in a way that prevents circuit crossing, enhancing reliability.
