摘要: A driving device of a multi-phase motor having plurality coils is provided. The includes back electromotive force (BEMF) detecting comparator connected to one the compare BEMF generated in end with midpoint voltage and generate detection signal, when starts be driven; an initial state unit configured detect rotation based on signal hall signal.
