The utility model discloses a manual release type large-torque electromagnetic brake which comprises a micro switch assembly and a handle assembly. The micro switch assembly consists of a first micro switch, a second micro switch and a detecting head, wherein the first micro switch and the second micro switch are mounted on two side faces of a stator shell body, and the detecting head is mounted on an armature; the top end of the detecting head is in contact with contacts of the first micro switch and the second micro switch respectively; the bottom end of the detecting head passes through the stator shell body and is matched with the armature in a threaded manner; and a first rotor and a second rotor are arranged between the armature and a stopping plate, and friction sheets are arranged on the first rotor and the second rotor. According to the manual release type large-torque electromagnetic brake, the mounting space is reduced through reducing the volume of the brake, the requirements of assembling can be met in a manner that equipment only provides a smaller mounting space, and the large torque is realized in a manner that a double structure is adopted in a limited space; and the working state of the brake is fed back to a system by using two sets of micro switches, and the wear states of the friction sheets are monitored, thus the automatic remote monitoring in special environments is realized.
