Latest Patents

Kota Sei holds a patent for a motor control device and method. This control device calculates a voltage command value for an inverter by executing feedback control that ensures the current value of a three-phase motor follows a specified current command value. The device includes a compensation calculator that calculates a correction voltage to compensate for torque ripple in the motor. This correction voltage is a sine wave that is in antiphase with the torque ripple, achieved by combining a real part and an imaginary part that share the same frequency. The compensation calculator determines the amplitudes of the cosine and sine wave components based on the current command value and the motor's rotation speed. This innovative solution addresses the challenges associated with torque ripple, improving the overall efficiency of motor control systems.
