The invention discloses a single-phase permanent-magnet synchronous motor magnetic field orientation control method and a permanent-magnet synchronous motor system. The magnetic field orientation control method comprises the following steps of determining a position of a rotor magnetic pole corresponding to a peak value of a counter electromotive force of a stator winding; detecting a peak value of a stator current flowing through the stator winding; detecting a position of a rotor magnetic pole corresponding to the peak value of the stator current; according to the position of the rotor magnetic pole corresponding to the peak value of the stator current and the position of the rotor magnetic pole corresponding to the peak value of the counter electromotive force of the stator winding, adjusting a trigger angle used for triggering a conduction switch device. Through determining the position of the rotor magnetic pole corresponding to the counter electromotive force peak value of the stator winding in advance, the position of the rotor magnetic pole corresponding to the counter electromotive force peak value fit the position of the rotor magnetic pole corresponding to the stator current peak value through control so that magnetic field orientation control is realized.
