With a total of 8 patents to his name, Mori's innovations have had a lasting impact on the industry.
Latest Patents
One of Mori's latest patents is for a brushless DC motor. This invention features a bridge that conforms to the tooth opening angle of the stator, positioned between two permanent magnets in the rotor. This design 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 and equal to or larger than half of that angle. This configuration increases the reluctance of the rib against the magnetic flux in a circumferential direction, effectively preventing leakage of the magnetic flux from the permanent magnet.
Another notable patent is for an electric power steering apparatus. This system includes a torque sensor that detects the steering torque applied to the steering wheel and a steering assist motor that is driven to rotate based on the detected torque. The motor operates under field weakening control in high-speed rotation areas. It is a brushless motor that comprises a rotor with multiple permanent magnets fixed in recesses within the rotor core. This innovative design allows for a steer-assisting force to be achieved during high-speed steering.
