Title: Minoru Kitabayashi: Innovator in Brushless Motor Technology
Introduction
Minoru Kitabayashi is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of motor technology, particularly in the development of brushless motors. With a total of 8 patents to his name, Kitabayashi's innovations have had a lasting impact on the industry.
Latest Patents
One of his latest patents is for a brushless motor, which features a rotary shaft of a rotor that includes a magnet with multiple magnetic poles arranged at equal intervals on its outer circumference. This design supports the rotary shaft at both ends by bearings. The inner ring of one bearing is externally fitted to the rotary shaft and held immovable in the axial direction. The outer ring of the bearing is loosely fitted into the support hole and positioned with belleville springs, allowing the rotary shaft and rotor to move axially within a movement amount of not greater than 2 mm.
Another notable patent is for a brushless DC motor. In this design, a bridge is provided between two permanent magnets in the rotor, conforming to the tooth opening angle of the stator. This configuration allows a magnetic flux for a reluctance torque to pass through the inner side of the permanent magnet. The opening angle of each rib on both sides of the permanent magnet is set to be equal to or smaller than the teeth interval opening angle, which increases the reluctance of the rib against the magnetic flux in a circumferential direction and prevents leakage of the magnetic flux from the permanent magnet.
