PURPOSE:To provide a commutatorless motor driving method for an electric- powered vehicle in which phase current does not decrease at the time of switching the conducting phase of a stator winding. CONSTITUTION:In the commutatorless motor driving method for motor vehicle wherein conduction and interruption of stator winding are performed based on the rotational position and rotational speed of rotor, conduction and interruption timings are advanced at first and then conduction start timing is further advanced by an interval tau1 ahead of thus advanced conduction start timing whereas interruption timing is delayed by an interval tau2 behind thus advanced interruption timing. |
