A ceiling fan motor with a double-cooling-air-path structure relates to the technical field of ceiling fan motors, overcomes the technical defects that a motor of an industrial ceiling fan is damagedand the like, and comprises a rotor assembly and a stator assembly, the rotor assembly comprises a rotor shell, a rotor body, an upper end cover and a lower end cover; air inlet holes are annularly arrayed in the upper end cover, vent holes are annularly arrayed in the hub, and air outlet holes are annularly arrayed in the lower end cover; the air inlet holes, the vent holes and the air outlet holes form a cooling air main path; an upper end cover groove is formed in the inner side surface of the upper end cover; a circular ring is arranged on the winding insulating plate; a gap between the groove of the upper end cover and the circular ring, a groove path on the stator core and a gap between the hub and the lower end cover form a cooling air bypass. Drip water is blocked by the circular ring and cannot enter the
