The invention relates to the technical field of electromagnetic brakes, in particular to an electromagnetic brake with an independent coil. The electromagnetic brake comprises a magnet yoke, the coil, an armature, a brake spring, a brake disc and an end cover. The magnet yoke is of a split structure and comprises a magnet yoke body around which the coil is wound, a magnet yoke outer ring arranged on the outer side of the magnet yoke body, and a magnet yoke end body used for connecting the magnet yoke body and the magnet yoke outer ring. The magnet yoke outer ring is provided with a through hole used for containing the magnet yoke body, and the magnet yoke outer ring is fixedly connected to the end cover through an adjusting bolt. The magnet yoke end body is detachably installed on the end face of the side, away from the end cover, of the magnet yoke outer ring. The magnet yoke is designed into the split structure, and the magnet yoke can be independently detached so that the coil can be conveniently taken out from the interior of the electromagnetic brake for replacement and maintenance; and meanwhile, it can be guaranteed that during maintaining, the size of an air gap of the electromagnetic brake is kept unchangeable, adjustment does not need to be conducted again after maintenance, and the maintaining speed is greatly increased.
