A brushless motor (18) which supplies currents to coils (U1, U2, V1, V2, W1, and W2) and rotates a rotor (27), the brushless motor comprising a control apparatus (37) which switches and selectively executes: first energization control to start energization to the coils (U1, U2, V1, V2, W1, and W2) at first timing, and to continue the energization for a first period to control the rotation number of the rotor (27); and second energization control to start energization to the coils (U1, U2, V1, V2, W1, and W2) at second timing advanced by an electric angle with respect to the first timing, and to continue the energization for a second period longer than the first period to control the rotation number of the rotor (27).
