| Zusammenfassung: | A detection control system comprises a sensing unit, a control module and a driving module. The detection control system applies to a motor which includes a rotor and a stator. The sensing unit electrically connects to the motor to sense a first and a second magnetic pole of the rotor cross a chip set between the rotor and the stator, and a third magnetic pole converts to a forth magnetic pole of the stator to generate a sensing signal. The detection unit of the control module detects a kickback voltage value generated from which a first current value converts to a second current value to calculate a minimum current value to generate a detection signal. A time counter unit accepts the sensing and the detection signal to calculate a first and a second time, and a discharging time. The driving module drives the rotor by accepting a control signal the control unit generates by controlling a transition time. |
