    Abstract: A magnetic field generator includes a plurality of magnets on support members disposed opposite to each other across a gap. The plurality of magnets include: first magnets having a magnetization direction orthogonal to a support surface of each of the support members; and second magnets having a magnetization direction parallel to the support surface, and form a Halbach magnet array. Either of the first magnets or the second magnets has a first dimension orthogonal to the support surface which is smaller than a first dimension of the other of the first magnets or the second magnets, either of the first magnets or the second magnets being formed into a recessed shape as viewed from a side of the gap.

    Abstract: A rotor having a plurality of wind turbine blades, a generator to be driven by rotation of the rotor, a pitch angle controller for controlling a pitch angle of the wind turbine blades according to a speed of a generator, and a comparing and selecting section are provided. When the voltage of the utility grid is a predetermined value or less, the pitch angle controller controls the pitch angle so that the wind turbine blades do not move to a fine side. Further, the comparing and selecting section compares a temporary pitch angle command value determined based on the speed of the generator with a previous value of a pitch angle command value, and when the temporary pitch angle command value is a command for controlling the wind turbine blades closer to the fine side than the previous value, outputs the previous value as a current pitch angle command value.
