る。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings regarding a linear electromagnetic brake. 1 and 2 show the principle of the linear electromagnetic brake according to the present invention, where 1 is an excitation coil, 2 is a yoke, 3 is an armature, 4 is a friction lining, 5 is a return spring, and 6 is an armature. The holder 7 is a drive pin.
The excitation coil 1 is wound around a yoke 2, and the yoke 2 is fixed in a U-shape with two parallel lines connected at one end and open at the other end. The armature 3 is suspended between two parallel linear portions of the yoke 2 in a bridging manner. Friction lining 4 is armature 3
It is fixed to the part corresponding to the yoke 2 of. The drive pin 7 slidably supports the armature 3 and is fixed to the armature holder 6.
The armature holder 6 is connected to an external moving body. The return spring 5 quickly releases the armature 3 from the yoke when the brake is released. In the above configuration, when a linear motion from the outside is transmitted to the armature holder 6 as shown by arrow a, when current is passed through the excitation coil 1, the yoke 2 is magnetized and the magnetic flux φ is transferred from the yoke 2 to the armature. Return via 3. Due to the action of this magnetic flux φ, the armature 3 overcomes the tension of the return spring 5 and is attracted to the yoke 2, the friction lining 4 is attracted to the yoke 2, and the friction force F=Pμ(P : suction force, μ : friction coefficient between the yoke and friction lining) is generated, which decelerates, brakes, and stops external linear motion. Next, when the current in the excitation coil 1 is cut off, the magnetic flux φ disappears, and the armature 3 is moved to the yoke 2 by the tension of the return spring 5.
, the armature 3 can move in a straight line.

は直線運動が可能となる。 An embodiment based on the above basic principle will be described with reference to FIGS. 3 to 5. In each figure, members that are the same as or equivalent to those shown in FIGS. 1 and 2 are designated by the same reference numerals. When implementing the above basic principle, it is necessary to guide the armature 3 so that it moves linearly while maintaining a constant distance from the yoke 2. In this embodiment, a guide bar 8 is provided parallel to the yoke 2. , the armature holder 6 is slidably fitted to the guide bar 8 via a guide metal 9. Additionally, mounting legs 10 are provided at both ends of the parallel portion of the yoke 2 to secure the entire device. Furthermore, the drive tie rod 11 is fixed to the armature holder 6 to transmit linear motion from the outside. The operation of this embodiment configured as described above is basically based on the principle described above, and when linear motion is transmitted from the drive tie rod 11 to the armature holder 6, the armature holder 6 moves toward the guide bar. The armature 3 moves linearly along the yoke 2 while keeping a constant distance therebetween. At this time, when the exciting coil 1 is excited, the armature 3 overcomes the tension of the return spring 5 and is attracted to the yoke 2, and the friction lining 4 is attracted to the yoke 2 to brake the movement of the drive tie rod 11. Next, when the current in the excitation coil 1 is cut off, the armature 3 separates from the yoke 2 and the drive tie rod 11
is capable of linear motion.

として動作する。 Although the electromagnetic brake has been described above, it can also be used as an electromagnetic clutch. In other words, if the yoke 2 is not fixed but is movable in a linear direction and connected to another object, when the yoke 2 is excited, the linear movement from the outside will be caused by the armature 3→
The friction is transmitted from the friction lining 4 to the yoke 2 and operates as a clutch.
