Title: Innovations of Junichi Asama
Introduction
Junichi Asama is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of electric motors and actuators, holding a total of 2 patents. His work focuses on enhancing the efficiency and functionality of motor control systems.
Latest Patents
Asama's latest patents include an innovative electric motor and a control device, as well as a motor control system. In his electric motor design, a magnetic bearing generates an electromagnetic force between multiple permanent magnets and a coil, which supports the rotation shaft in an axis line direction. This design allows the rotation shaft to be inclined with a rotation center line, utilizing the bearing side as a fulcrum. An electronic control device regulates the current flowing to the coil, ensuring that the rotation shaft aligns with the rotation center line due to the supporting force generated by the electromagnetic interaction. This results in a freely rotatable shaft supported by both a magnetic bearing and a traditional bearing.
Additionally, Asama has developed an inchworm actuator that can move a movable body relative to a stationary body. This actuator selectively prioritizes either displacement speed or resolution based on usage conditions. The inchworm actuator features a movable body supported between first and second guides made of magnetic material. It incorporates a voice coil motor, supported by first and second support legs, which also consist of magnetic material and magnetic field-forming coils. The toggle mechanisms convert the displacement input from the voice coil motor, transmitting the resultant displacement to the support legs.
