Abstract:
    This means consists of a digital processor, a driving IC circuit, a mini-motor and a photo-switch. First, defines the frequency and the driving time of impulse width modulation (IWM) and regulates the IWM occupied-empty ratio of the driving signal. Second, decides that if the time meets the practical need; if no, continuing to regulate; otherwise, using the reverse direction brake. Re-regulates the occupied-empty ratio and decides the impulse number of the reverse direction brake. Then defines whether the reverse direction brake meets the practical need. The method of motor driving and braking can raise the integrated feature of this product and the coherence of the match between components.
