Motor

The utility model relates to a motor, it includes frame, stator core, rotor core, forced cooling fan, and stator core sets up at rotor core outsidely, and the one end outside of frame is equipped withthe forced cooling fan, still includes air intake and air outlet, the air intake sets up the one end at the frame, and the air intake is connected with the air outlet of forced cooling fan, the air outlet sets up the other end at the frame, and the circle surface is equipped with the ventilation groove in the frame with stator core phase -match department, rotor core is equipped with axial through's ventilation hole. The utility model discloses because set up forced cooling fan and business turn over wind gap at the frame, partly amount of wind passes through from the groove that ventilates between frame and stator core, takes away the heat that stator core and winding overhang produced, partly amount of wind passes through from the ventilation hole on the rotor core, takes away the heatthat rotor core and windin
