PROBLEM TO BE SOLVED: To provide a single-phase brushless motor that implements high efficiency and the like.SOLUTION: The single-phase brushless motor includes: a plurality of coils 3b configured in a single phase; a sensor 5 for detecting a magnetic pole change with rotation of a rotor 2; and an energization mechanism 4 for driving the rotor 2 at a predetermined rotational speed. The energization mechanism 4 can switch between rectangular wave energization in which an applied voltage applied to the coils 3b represents a rectangular waveform and pseudo sinusoidal wave energization in which the applied voltage represents a pseudo sinusoidal waveform. The switching between the rectangular wave energization and the pseudo sinusoidal wave energization is performed by gradually changing the waveforms. |
