Claims

[Scope of utility model registration request]

(1) In an electromagnetic brake that mechanically controls a movable body to be in a released state or a restrained state by a given electric signal, the fixed side friction plate that constitutes the electromagnetic brake is attached to the frame of the machine, etc. to which the electromagnetic brake is attached. Due to electrical continuity between the insulated first detection terminal connected to the fixed friction plate and the second detection terminal connected to the frame, the electromagnetic brake is released after the release delay time has elapsed. and a restraint condition after a restraint delay time has elapsed, and the detection signals of these two states are made to coincide with the ON/OFF timing of power from actuators installed separately on the movable body.

(2) The electromagnetic brake according to claim (1) of the utility model registration claim, characterized in that an insulator is attached to the fixed seat.

(3) The electromagnetic brake according to claim (1) of the utility model registration, characterized in that the fixed seat is an insulator.

(4) The electromagnetic brake according to claim (1) of the utility model registration, characterized in that the fixed side friction plate support is an insulator.
