る。Next, the operation will be explained. When energized, the voltage applied to the stator coil 10 causes the cylindrical rotor 11 provided with the permanent magnets 12 to rotate, and the °ζ flywheel 2 to rotate. During a power outage, current is generated in the stator coil 10 due to the rotation of the cylindrical loaf 11 as the flywheel 2 rotates due to inertia. In other words, the generator-motor section 8 applies rotational force to the flywheel 2 when energized, and during a power outage, the rotational force of the flywheel 2 is converted into electrical energy, which is then used to supply power from the stator coil 1° to an external load. Acts as a generator motor section.
