The invention relates to a permanent magnetic traction motor, to be specific, relates to a high speed train totally enclosed type permanent magnetic traction motor, which is used to solve the problems of the conventional totally enclosed type permanent magnetic motors such as poor cooling effect and inability of controlling internal even temperature rising of motor. The technical scheme provided by the invention is that a base is provided with axial air vents; end covers are provided with internal air ducts, which are connected with the base in a sealed manner, and the end covers, the internal air ducts, and the base air vents are used to form cooling wind paths in an encircled manner; the end covers are provided with cooling air inlet holes, and the outer sides are provided with cooling air outlet holes; two ends of a rotating shaft are fixedly provided with sealing discs, which are disposed between the end covers and the base, and are connected with the end covers in a sealed manner, and blades are fixedly disposed on the sealing discs between the cooling air outlet holes and the cooling air inlet holes; and self-circulation sectors are fixedly disposed on permanent magnet baffle plate clamping rings. The high speed train totally enclosed type permanent magnetic traction motor is advantageous in that 1, the three wind paths are used for the independent temperature control of the integral body of the motor; 2, the internal temperature rising of the motor is controlled in a balanced manner, and the overhigh temperature rising or the uneven temperature rising of the motor is prevented; 3, the independent cooling wind paths are designed for bearings, and then failure caused by the overhigh temperature of the bearings caused by thermal radiation and heat conduction is prevented.
