Description of the Invention: [Technical Field] The present invention relates to an improvement of an electromagnetic brake, in particular, an electromagnetic coil of an electromagnetic brake has magnetic lines of force concentrated in a magnetic working area to maximize magnetic attraction efficiency And does not affect the function of other parts. [Prior Art] A commonly used electromagnetic brake is equipped with an electromagnetic coil in the brake device, and the electromagnetic attraction is generated by the electromagnetic coil as the braking force of the pressing spring. When the power is lost, the braking force of the brake is generated by the restoring force of the spring. As shown in the fifth figure, the electromagnetic brake 70 is provided with a fixing seat 71. The groove 73 N ' of the one end bushing of the fixing seat 71 can accommodate an electromagnetic coil 74. The electromagnetic coil 74 is surrounded by an enameled wire. As a ring-like appearance, when the magnetic force generated when the electromagnetic coil 74 is energized generates a magnetic effect in addition to the movable friction plate 75, the electromagnetic coil % causes a magnetic force effect on the transmission shaft 76 placed in the ring. % of the drive shaft • When the magnetic effect occurs, the parts mounted on the drive shaft 76 will be damaged and affect the service life. For example, the bearing, the magnetic force, the line 8 will hinder the operation of the bearing and reduce the speed of the drive shaft 76. And the iron dust generated during the mechanical operation will be absorbed by the transmission shaft 76. If the iron dust enters the bearing, the service life of the bearing will be affected; The magnetic force generated by the magnetic coil 74 is not all applied to the movable friction plate 75, and the electromagnetic coil 74 partially generates a magnetic coil to the drive shaft 76, so that the magnetic attraction force generated to the movable friction plate 75 is lowered. Brake structure, due to the lack of structural design of the electromagnetic coil, resulting in
