Latest Patents
Ikumi Satoh's latest patents include innovative designs for an electromagnetic actuator for a valve stem and a motor-operated valve. The electromagnetic actuator features a stator core with concentrated coils wound around salient poles, positioned outside a nonmagnetic tubular member. This design allows for the rotor to drive a threaded operating shaft, facilitating the reciprocal movement of an objective member. Furthermore, the actuator incorporates permanently magnetized pole-pairs along the stator’s salient poles, enabling it to operate as a pulse motor through the alternating excitation of coils.
The motor-operated valve, on the other hand, comprises a stator external to a nonmagnetic tubular member, which allows fluid flow. It includes stator coils and permanent magnets arranged in a regular pitch. The rotor, supported within the tubular member, contains induction teeth that align with the permanent magnet's pole-pairs, ensuring precise control. Additional mechanisms are incorporated to convert the rotor's rotation into linear movement for valve operations.
