In the figure, (1) is a stator, (8) is a stator, (1) K resin (3) and an excitation coil fixed by K. 1 (4) is a pair of pre-lits (b) formed concentrically in the circumferential direction to block magnetic flux, and a specific friction surface that is divided.

) is an armature (7) having a magnetic flux blocking slit which is arranged in the axial direction of the rotor (4) with a gap g therebetween and is formed to face the middle part of the slit (b) of the rotor (4).
) is a leaf spring whose one end is attached to the armature (6) with a rivet (8) and the other end is attached to the boss (9) with a rivet (to), supporting the armature (6) so that it can move in the axial direction. .

When the armature (6) is deenergized, the armature (6) is opposed to the rotor (4) by the leaf spring (7), and is rotated by the rotational force transmitted to the pulley via the bell (not shown). Only the rotor (4) is rotating, and the armature (6
) is a stationary MK. Next, when the excitation coil (2) is energized, a magnetic flux Φ is generated in the magnetic path shown by the dotted line, and the armature (
6) is attracted to the pointer (4) against the elastic force of the leaf spring (7). Therefore, the rotating rotor (4)K also rotates the armature (6), thereby rotating the load through a rotating shaft (not shown).

どの磁気回路部の断面積、１：１
を小さくして軽量化した場合に顕著に現われる。In this way, a device having a friction surface of 1 to - has the characteristic that the magnetic flux reciprocates twice, so the attractive force is doubled and the device is made smaller. However, since the magnetic flux Φ is a complicated flow, it does not work effectively at all, and the magnetic flux Φ that works effectively on
In addition to this, a leakage magnetic flux φ shown by a dashed line is generated. This leakage magnetic flux φ includes φ1 that flows outside the friction surface of the rotor (4) and the armature (6), and φ1 that flows outside the friction surface of the rotor (4) and the armature (6) without flowing to the rotor (4) side. There are two types: φ2, which flows only to the armature (6), and φ3, which flows to the space outside the armature (6). This becomes noticeable when the weight is reduced by reducing the 1:1 cross-sectional area of the magnetic circuit parts such as the rotor (4) and stator (1).
しかしいづれも磁束は励磁コイル（２）を中心にして流
れるためｉ−夕（４）の摩擦面一にはすべての磁束が流
れ込んでいる。However, in both cases, the magnetic flux flows centered around the excitation coil (2), so all of the magnetic flux flows into the friction surface of the coil (4).

磁率をμ０とすると吸引力は、１ｇｍ−８
Ｐ−一酉一
となり面積Ｓよりも磁束密度Ｂｓｌ高める方が吸引力が
太き（なることがわかる。Here, if the area of the friction surface is 8, and the magnetic flux density tBgs and magnetic permeability of the friction surface is μ0, the attractive force is 1 gm-8 P-1, and the attractive force is larger when the magnetic flux density Bsl is higher than the area S ( I know what will happen.

同一としたのに対し、摩擦面一〜−警擦面−の６０〜８
０％の面積とすることによって磁束密度Ｂｇを高め、吸
引力を増加する。Therefore, due to the influence of the leakage magnetic flux, the magnetic flux density Bg decreases in the friction (on the wheel (b)), so the attractive force also decreases.
While the friction surface is the same, the friction surface is 60 to 8.
By setting the area to 0%, the magnetic flux density Bg is increased and the attractive force is increased.
このように摩擦面一〜−の面積を小さくすることによっ

伝達力を増大することができる。By reducing the area of the friction surfaces 1 to - in this way, the overall outer diameter becomes smaller, making it possible to downsize the device and increase the transmission force.

In the electromagnetic coupling device according to the invention, a pair of slits are formed concentrically in the circumferential direction on the friction surface of the rotor, and a circumferential slit is formed in the armature in the center of the pair of slits. It is divided and formed by the slit of the armature and the opposing part of the slit of the armature, and the area of all the other friction surfaces is smaller than the area of the innermost friction surface among the nine friction surfaces, improving the suction force and making it compact. can do.
