Abstract: PURPOSE: A back electromotive force detecting circuit is provided to simplify a hardware and detect back electromotive force exactly by using an inverter circuit, a stator coil, a plurality of sampling/hold circuit, and a plurality of control switches. CONSTITUTION: An inverter circuit comprises a plurality of upper driving transistor, a plurality of lower driving transistor, and a diode. The inverter circuit is switched by switching signals. One side terminal of a stator coil is connected to the contact point of the upper driving transistor and the lower driving transistor, and the other side terminal of the stator coil is connected to a neutral point. The back electromotive force detecting circuit comprises a sampling/hold circuit and a plurality of control switch.
