A motor magnet fixing device includes two press rings, a plurality of magnets and locking members. A least one of the two press rings has its annular surface disposed with a plurality of projecting members spaced apart equidistantly. Each projecting member is axially bored with a fixing hole, having its opposite sides respectively formed with an engage recess. The magnets are clamped between the two press rings and respectively engaged between the adjacent projecting members of the two press rings. Each magnet has its opposite ends respectively formed with an engage projection to be engaged in the engage recesses of the projecting members of the press rings. The locking members are respectively inserted in the fixing holes of the projecting members of the press rings to combine the press rings together and fix the magnets between the press rings.
