PROBLEM TO BE SOLVED: To provide a brushless motor capable of suppressing torque ripple in a rotor.SOLUTION: A brushless motor 18 for rotating a rotor 27 by supplying a current to coils U1, U2, V1, V2, W1, W2 includes a drive circuit 37 for switching and executing first energization control for starting energization to the coils U1, U2, V1, V2, W1, W2 at first timing and continuing the energization over a first period to control a rotational frequency of the rotor 27 and second energization control for starting energization to the coils U1, U2, V1, V2, W1, W2 at second timing advanced from the first timing by an electric angle and continuing the energization over a second period longer than the first period to control the rotational frequency of the rotor 27. |
