[Problem] The invention provides a unidirectionally-energized brushless DC motor including an AC voltage output winding, and the brushless DC motor simultaneously exerts a motor function of being able to continuously obtain a constant torque and a power generation function of being able to obtain a continuous electromotive force. [Solving Means] The brushless DC motor includes a disk 5 that is attached to a frame 3, a plurality of plate-like permanent magnets 6 that are disposed on the disk 5 at equal intervals around the disk 5, magnetic cores 70(A) that are fixed to the frame 3 according to the plurality of permanent magnets 6, windings 71(A) each of which is wound around the magnetic core 70(A) and to which DC power is supplied, a predetermined number of magnetic cores 70(B) that are fixed to the frame 3, and windings 71(B) each of which is wound around the magnetic core 70(B) and connected to a power consumption device. The permanent magnets 6 are located such that an angle formed by a straight line passing through the center of the disk 5 and the center of the permanent magnet 6 and a normal line in the center of a magnetic pole plane of the permanent magnet 6 ranges from 0° to 60°.
