A power generator (1, 1a, 1c, 1d) according to an embodiment includes a rotor shaft (170, 170a, 170c, 170d), a slip ring (15), a detecting shaft (180), and a position sensor (16, 16c, 16d). The rotor shaft (170, 170a, 170c, 170d) through which wires from a propeller (130, 130_2, 130_3) are inserted rotates with the propelled (130, 130_2, 130_3). The slip ring (15) is coupled to the rotor shaft (170, 170a, 170c, 170d) at one end. The detecting shaft (180) is provided at the other end of the slip ring (15) and rotates along with the rotor shaft (170, 170a, 170c, 170d). The position sensor (16, 16c, 16d) detects the rotational position of the detecting shaft (180), thereby detecting the rotational position of the propeller (130, 130_2, 130_3). |
