Abstract
A protect-control device capable of limiting current for reducing noise resulting from switchover of a motor includes a motor coil set, a driving unit, a sensing unit and a control unit. The motor coil set constitutes a motor. The driving unit is electrically connected to the motor coil and provides a driving level to pass through the motor coil for driving the motor. The sensing unit is electrically connected to the motor coil set, provides a preset reference level, detects the driving level, compares the driving level to the preset reference level and outputs identifying signal. The control signal is electrically connected to the driving unit, the sensing unit and a Hall component, adjusts the driving level based on the identifying signal for driving unit output maintaining a basic duty cycle.
