PURPOSE:To make a decision that a motor has stepped out when an output signal from a counter-electromotive force detector deviates from a specific conduction switching range. CONSTITUTION:The driver for brushless motor comprises motor driving coils 1-3 for a plurality of phases, a plurality of driving transistors 4-9 mounted on the driving coils 1-3, a circuit 10 for sequentially transmitting conduction switching signals for the driving coils 1-3 to the driving transistors 4-9, and a counter-electromotive force detector 11 for the driving coils 1-3. |
