取扱いが煩わしい等の欠点がある。 For this reason, the distance between the frequency power generation coil and the stator yoke plate is large, and the magnetic resistance increases.
The power generation output of the frequency power generation coil is low. Furthermore, when the frequency power generation coil is opposed to a frequency power generation magnet provided separately from the rotor magnet that opposes the stator coil, the frequency power generation coil is located above the stator coil, so there is a risk that the rotor magnet will be affected. There is. Furthermore, since the printed board for the frequency power generation coil is mounted on the stator coil, it is necessary to extract the power generation output from this printed board to the mounting surface of the stator coil using two enamelled wires, which makes handling the enameled wires cumbersome. There are drawbacks such as.
