Latest Patents

Yamamura's latest patents include a phase adjustment method, a correction value calculation device, a motor control device, an electric actuator product, and an electric power steering device. The phase adjustment method is designed for a rotation angle sensor that detects the rotation angle of a rotor in a brushless motor. This method involves measuring the first and second rotation speeds when the motor is driven with the same torque command current in both clockwise and counterclockwise directions. It calculates a correction value to adjust the phase of the rotation angle sensor, thereby minimizing the rotation speed difference between the two measurements.

Another notable patent is the calibration method for a rotation angle calculation device. This method allows the rotation angle calculation device to calculate a rotation angle based on sensor detection signals and transmit this data to a calibration device. The calibration device then measures the actual rotation angle and compares it with the transmitted data to acquire calibration data, ensuring accurate rotation angle calculations.
