When the power is turned on, the stator winding 4 and the excitation winding 14 are energized, the fixed core 13 is energized, and the movable core 1
2 and the pressing member 11 are sucked against the elastic force of the first elastic body 17. Therefore, the pressing force on the braking surface 6a against the brake plate 9 disappears, and the rotor shaft 7 and the brake plate 9 rapidly start rotating, and at the same time drive the load directly connected or connected to the rotor shaft 7. Furthermore, when the operation switch of the electric motor 1 is opened, the stator winding 4 and the excitation winding 14 are de-energized, the fixed iron core 13 is deenergized, and the elastic body 17 is deenergized.
The elastic force acts on the brake plate 9 via the movable iron core 12 and the pressing member 11. The brake plate 9 is guided by the spline portion 7a, moves toward the braking surface 6a, and is pressed against the braking surface 6a, and the braking torque generated at that time rapidly brakes the brake plate 9 and the rotor shaft 7. 7 and prevent load ellipse.

う欠点があつた。 The conventional electromagnetic brake device is constructed and operates as described above, but in particular, the spline portion 7a of the rotor shaft 7 and the spline portion 9a of the brake plate 9 mesh with each other through the top gap A and the back gap B. As a result, the brake plate 9 swings relative to the rotor shaft 7 during rotation of the rotor shaft 7, producing abnormal noise, and the respective spline portions 7a and 9a wear out prematurely.
