摘要： A motor control apparatus includes a sensing module, a phase modulating module, a duty cycle modulating module and a driving module. The sensing module detects a motor to generate a sensing signal. The phase modulating module receives the sensing signal and generates a phase modulation signal in accordance with the sensing signal. The duty cycle modulating module receives the phase modulation signal and generates a duty cycle modulation signal in accordance with the phase modulation signal. The driving module receives the duty cycle modulation signal and generates a motor control signal for controlling the motor in accordance with the duty cycle modulation signal.

摘要： A motor control apparatus and a motor control method determine whether the motor is in a back-pressure area so as to provide different rotation-speed control signals. When the fan is in the low duty cycle, a first circuit loop is switched on, so that the fan has more accurate rotation speed. When the fan is in the high duty cycle, a second circuit loop is switched on, so that the rotation speed of fan does not be limited to a constant rotation-speed as the fan enters the back-pressure area. Thus, the fan has larger airflow quantity and higher airflow pressure.

摘要： A modularized control circuit with a signal-capturing function for a fan motor is disclosed. The modularized control circuit includes a driven circuit and a microcontroller integrated circuit. The driven circuit is electrically connected to the fan motor to produce at least one analog driven voltage signal, thus driving the fan motor. The microcontroller integrated circuit is electrically connected to the driven circuit and includes a signal-capturing module, a control unit, and a driven signal generator. The signal-capturing module receives an external pulse signal to produce a cycle-capturing signal. The control unit is connected to the signal-capturing module and receives the cycle-capturing signal to produce a control signal. The driven signal generator is connected to the control unit to receive the control signal, thus producing a plurality of switch driven signals for controlling the driven circuit.
