Latest Patents

Eri Kishimoto holds a patent for a "Driving apparatus for sensorless fan motor." This invention features a back electromotive force (BEMF) detection circuit that generates a rotation detection signal. This signal indicates a comparison result between electromotive force voltages that occur at the terminals of multiple coils and an intermediate-point voltage. The rotor position detection circuit generates a signal indicating a stopped rotor position. Additionally, an internal start-up synchronization signal generating unit produces a predetermined-frequency forced synchronization signal. Upon receiving a fan motor start-up instruction, a driving signal synthesizing circuit generates a driving control signal based on the rotor position detection signal. This innovative approach allows for a sensorless driving operation to start based on the rotation detection signal when back electromotive force voltage occurs.
