Zusammenfassung:The invention relates to a wet-type friction braking permanent magnet motor which comprises a permanent magnet motor, a braking mechanism, a hydraulic system monitoring device and a braking torque monitoring device. An outer tooth hollow shaft of the braking mechanism is connected onto a fixed shaft in a sleeving mode and rotates and axially moves along with a permanent magnet motor shaft; a motor end cover of the permanent magnet motor is used as an end cover of the braking mechanism and is directly and fixedly connected with a shell-inner gear ring, a shell-oil cylinder and the braking mechanism end cover of the braking mechanism; an inner tooth friction plate set is embedded in outer teeth of the outer tooth hollow shaft; and an outer tooth friction plate set is embedded in inner teeth of the shell-inner gear ring. According to the wet-type friction braking permanent magnet motor provided by the invention, long-time operation and safe braking of a belt conveyor driven by the wet-type friction braking perma
