Claims

[Scope of Claim for Utility Model Registration] 1. A power generation section consisting of a rotor consisting of a permanent magnet for power generation fitted and attached to a rotating shaft, a fixed magnetic pole and yoke around which a coil is wound, and a power generation section located on one side of the power generation section. , a permanent magnet for position detection fixed on a rotor yoke fitted and fixed to the rotating shaft, and a printed circuit board opposite to the permanent magnet for position detection and provided on the opposite side of the power generation section of the rotor yoke. a rectifier consisting of a detection section consisting of a position detection element, and an electronic switch and an amplifier that switch the AC output voltage of each coil of the power generation section based on the output of this detection section to obtain an output voltage proportional to the rotation speed of the rotating shaft. What is claimed is: 1. A speedometer generator comprising: a magnetic shield plate that rotates together with the rotating shaft; and a magnetic shield plate that rotates together with the rotating shaft is inserted between the power generating section and the detecting section. 2. The speedometer according to claim 1, wherein the magnetic shield plate is made of a magnetic material, and the permanent magnet for position detection is fixed to the side surface of the magnetic shield plate on the detection part side.
