Embodiment Construction

[0014] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0015] The air-cooled motor shown in the accompanying drawings includes a front end cover 1, a housing 2, and a rear end cover 3; the front end cover 1 includes a front cover body 1.1, a flange 1.4, and ribs 1.3; the ribs 1.3 are arc-shaped plates, The number is an odd number within 3 to 15 (in this embodiment, the number is 11), and the middle part of the front end cover body 1.1 is provided with a bearing hole; The rib plate 1.3 around the bearing hole of the cover body 1.1 is connected together; the rib plate 1.3 forms a cooling air duct with the right end face of the front cover body 1.1 and the left end face of the flange 1.4, and the number of cooling air ducts is the same as that of the rib plate 1.3; On the section passing through the central axis of the bearing hole of the front end cover body 1.1, the closer the cooling air ch...

Abstract

The invention discloses an air-cooled motor, comprising a front end cover, a housing and a rear end cover; the front end cover includes a front end cover body, a flange and a plurality of rib plates;the middle of the front end cover body is provided with a bearing hole; the flange and the front end cover body face each other in axially spaced manner and are connected together through the multiplerib plates evenly distributed around the bearing hole of the front end cover body; cooling air passages are formed between the rib plates and the right end face of the front end cover body and left end face of the flange; an air guide hood is axially connected to the inner end face of the rear end cover; the rib plates are arc plates; the air guide hood is a frustum-shaped member having streamlined vertical section, with the large diameter end facing right and the small diameter end facing left. The air-cooled motor is further characterized in that the number of the rib plates is an odd number of from 3 to 15; on the section passing by the center axis of the bearing hole of the front end cover body, the closer the cooling air passages, formed between the rib plates and the right end faceof the front end cover body and left end face of the flange, to the center axis of the bearing hole of the front end cover body, the larger its axial size. The air-cooled motor has high cold air speedand good heat-dissipating and cooling effects.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor. Background technique [0002] Ordinary motors generate a certain amount of heat during operation. If the heat cannot be discharged in time, it will accumulate and become harmful until it affects the service life of the motor. Cooling measures have been taken in the prior art. The structure is that the left and rear end covers of the motor are provided with axial through holes, and the cold air is sucked into the motor from the ventilation holes provided on the rear end cover wall, and the flow direction of the cold air is from From right to left, until it flows out from the ventilation hole provided on the front cover wall, the cold air takes away part of the heat and has a cooling effect. However, in the prior art, less cold air enters the motor, the flow speed is not fast, the heat taken away is limited, and the cooling effect is limited. For the motor with a large cal...
