Abstract

PURPOSE:To ensure a stable rotation of a rotary shaft, by press-bonding the 2nd wheel to the 1st wheel to connect them into a body by the function of a permanent magnet and an electromagnet. CONSTITUTION:The current is flowed to the coil of an electromagnet 6, and the 2nd flywheel 2 is moved toward an arrow (a) by the magnetic sucking force of the magnet 6 to be press-bonded to the 1st flywheel 1. Under such conditions, a rotary shaft 3 is turned by a driving motor 4. Thus both flywheels 1 and 2 turn in a body to ensure a stable rotation with a large moment of rotation. After this, the backward current is flowed to the coil of the magnet 6, and thus the magnet 6 and a permanent magnet 5 repel each other. As a result, the 2nd flywheel 2 is moved toward an arrow (b) to separate from the wheel 1. Thus a rotary shaft 3 turns with only the wheel 1 to reduce the moment of inertia, and rise is secured up to a prescribed rotational frequency in a short time.
