His work focuses on improving the efficiency and assembly processes of electric motors, showcasing his expertise and innovative spirit.
Latest Patents
One of Sumi's latest patents is a method of assembling a stator for an electric motor. This method involves dividing the stator into a pole portion and a yoke portion, with a winding on the insulated pole portion. The yoke portion is forcibly enlarged outwardly, allowing the tip ends of the projections of the pole portion to fit into the recesses of the yoke portion. The design ensures that the opposing surfaces of each recess are parallel, and the bottom surface is aligned with the outer peripheral surface of the yoke portion. This innovative approach reduces the press-fitting load during assembly, facilitating the construction of large-sized stator iron cores and enhancing the output of electric motors.
Another significant patent by Sumi is a method of making a resin-molded motor. This motor consists of a rotor and a laminated stator with axially and radially extending slots that define pole pieces. The resin material is molded within the slots for insulation and bonding, while a cylindrical resin shroud is positioned at each end of the stator. The design includes a steel sheet bracket that supports the rotor and ensures the windings are properly connected for power supply. This innovative construction method enhances the durability and performance of the motor.
