Latest Patents

Fukumoto holds a patent for a motor-driving apparatus. The invention aims to accurately and reliably detect the rotational positions of a rotor, even in the presence of noise overlapping inductor voltage. The motor-driving device operates by supplying predetermined drive signals to stator coils corresponding to each phase of a DC brushless motor. It includes a drive-signal-generating unit that creates drive signals by switching direct current power based on a pulse-control signal. Additionally, a control-signal-generator unit generates the pulse-control signal, which intermittently controls the drive-signal-generating unit. This setup allows for the detection of the rotor's rotational position and velocity based on inductor voltage obtained from the stator coils during specific periods.
