No. 3-135143) is provided. In this method, a cylindrical rotating cylinder is fixedly mounted on a rotating shaft connected to a receiving roller or the like, and an electromagnet formed by winding a coil around a disk-shaped body is disposed inside the rotating cylinder. A magnetic pole portion on the outer periphery of the electromagnet is opposed to the rotating cylinder with a small gap, and the inner peripheral portion is rotatably supported on a fixed support member via a slip ring to supply electricity to the winding. Conduction is possible.

Accordingly, the moment of inertia of the rotary cylinder increases by the amount of the electromagnet, and the load applied to the receiving roller increases. In order to reduce the load, energization to the electromagnet is cut off, and the electromagnet section and the rotary cylinder section are separated to reduce the moment of inertia of the rotating section.

磁石を回転体の軸方向に移動させる調整機構により前記
間隙を調整するように構成したことを特徴としている。According to the present invention, in order to solve the above-mentioned problems, a disk-shaped rotating plate made of an electric conductor is fixed to a fixed shaft interlocked with a receiving roller, and the shaft of the rotating shaft is fixed. A permanent magnet fixed to a supporting member movable in a direction is opposed to the rotating plate with a small gap, and a rotating body is positioned in a magnetic field of the permanent magnet. The gap is adjusted by an adjusting mechanism that moves the gap in the axial direction of the rotating body.

荷抵抗となる。When the rotating plate is rotated within the magnetic flux of the permanent magnet which is connected to and supported by the receiving roller made of an electric conductor, the rotating plate cuts off the magnetic flux, thereby generating an eddy current in the rotating plate. When the eddy current cuts the magnetic force line from the permanent magnet at right angles, an electromagnetic force acts on the rotating plate in a direction opposite to the rotating direction of the rotating shaft, and this electromagnetic force becomes a braking force of the rotating shaft, that is, a load resistance.

簡単な手法で施行できる。Therefore, unlike the prior art, no electric energy is used, so that energy can be saved and installation and operating costs can be reduced by simplifying the apparatus. The adjustment of the electromagnetic force, that is, the load resistance, can be performed by a simple method of changing the gap between the permanent magnet and the rotating plate by the adjusting member.
