Latest Patents
Ogata holds a patent for an inverter control apparatus designed to control the command frequency and command voltage supplied to an inverter. This apparatus is capable of providing AC power of a desired frequency to an induction motor. It operates by receiving a requested rotational speed of the motor and detecting the actual rotational speed through the frequency of a fluctuation component of the drive current. The difference between the requested and actual speeds, known as the slip amount, is used to adjust the command frequency. Additionally, the command voltage is set based on the minimum monitored drive current, allowing the apparatus to maintain low power consumption while compensating for slip ratios to keep the motor speed at the target level.
