Latest Patents

One of Junichi Nagai's latest patents is an electric motor with an air-cooling system. This design includes a covering member that encases the outer periphery of a stator core, enhancing the cooling efficiency of the motor's air-cooling system. The covering member is securely fixed to the stator, creating a cavity that is in fluidic communication with air passages formed directly in the stator core. When a blower unit mounted on the motor operates, ambient air surrounding the motor is drawn into the cavity. The air then flows from the cavity into the air passages, effectively absorbing heat generated in the stator from the outer peripheral surface of the stator core and the tubular wall surfaces of the air passages. Finally, the heated air is discharged from the air passages out of the motor.

Another notable patent is the method and device for producing a squirrel-cage rotor for an induction motor. This innovation further showcases Nagai's expertise in enhancing motor design and functionality.
