Latest Patents

Zhou Xiao's latest patents include a motor drive controller and a motor drive control method. The motor drive controller is designed to enable a locking energization operation while preventing an increase in temperature of a coil. This controller features a motor drive section that selectively energizes coils with multiple phases of a motor, along with a locking energization control section. This section performs a locking energization operation when the motor is started or restarted, holding the rotor of the motor in a position corresponding to the coil where the lock current flows. Additionally, the locking energization control section switches the locking energization pattern for applying the lock current in the coil, ensuring optimal performance during operation.

The motor drive control device includes a control circuit unit that outputs a drive control signal for advance-angle control of the motor. It also features a motor driving unit that outputs a drive signal to the motor based on the control signal, and a current detecting circuit that detects a voltage value corresponding to the motor's drive current. The control circuit unit detects the cross-timing between the detected voltage value and reference voltage values, performing advance-angle control to adjust the phase of the drive current accordingly.
