Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, for the utility model discloses an embodiment, including casing 1, casing 1 both ends are connected respectively and are provided with silence ring 2 and rear end cap 3, evenly are provided with exhaust hole 201 on the

silence ring

2, and 2 another end connections of silence ring are provided with front end housing 4, and casing 1 is inside to be provided with stator module 5 and

rotor subassembly

6, and 6 outsides of rotor subassembly still are provided with rotary encoder, and rotary encoder makes with rear end cap 3 as an organic whole, is provided with breather pipe 7 on the rear end cap 3, breather pipe 7 and the inside intercommunication of casing 1. The motor during operation, stator module 5 and rotor subassembly 6 can produce the heat usually, are connected breather pipe 7 and outside air supply, and inside gaseous continuously carrying casing 1, cooling stator module 5 and rotor subassembly 6, later gaseous from exhaust hole 201 discharge to casing 1 outside to the realization is to the cooling of motor, guarantees that the motor works steadily for a long time.

In this embodiment, to some powerful motors, the heat that its produced will be very big to it is provided with supplementary breather pipe 8 to lie in breather pipe 7 one side on rear end cover 3, and supplementary breather pipe 8 is connected with outside air supply simultaneously, ventilates to casing 1 inside simultaneously through breather pipe 7 and supplementary breather pipe 8, thereby improves radiating effect, makes high-power motor can normally work continuously.

In this embodiment, in order to make the airflow inside the casing 1 flow uniformly, the fan 9 is disposed on the rotating shaft 601 of the rotor assembly 6, and the rotating shaft 601 drives the fan 9 to rotate when rotating, so that the air inside the casing 1 can reach every position uniformly, thereby improving the cooling effect.

In this embodiment, because the gas is discharged from the gas discharge holes 201, there is a great noise, so that the size of the gas discharge holes 201 is gradually reduced from the inner side to the outer side of the mute ring 2 to design, the noise of the discharged gas can be effectively reduced, and meanwhile, in order to control the gas outflow state, the mute ring 2 is designed to include an inner ring 202 and an outer ring 203, so that the outer ring 203 and the inner ring 202 can rotate relatively, the gas discharge holes 201 are correspondingly arranged on the inner ring 202 and the outer ring 203, when the gas in the casing 1 does not need to be discharged to the outside, only the outer ring 203 needs to be rotated, so that the gas discharge holes 201 on the outer ring 203 and the gas discharge holes 201 on the inner ring 202 are separated, and the gas discharge holes 201 can be blocked; when it is required to discharge the air inside the cabinet 1 to the outside, the outer ring 203 is rotated such that the exhaust holes 201 of the outer ring 203 communicate with the exhaust holes 201 of the inner ring 202, so that the air is discharged to the outside through the exhaust holes 201.

In this embodiment, the fan 9 is located at the exhaust hole 201, and the air inside the casing 1 can be rapidly and uniformly exhausted from the exhaust hole 201 by the action of the fan 9.

In this embodiment, all be provided with visor 10 on breather pipe 7 and the supplementary breather pipe 8, when not using, visor 10 can protect breather pipe 7 and supplementary breather pipe 8, avoids impurity to enter into inside casing 1 simultaneously.

In actual operation, at first install breather pipe 7 and supplementary breather pipe 8 on rear end cap 3, be connected outside air supply with breather pipe 7 and supplementary breather pipe 8, in order to improve refrigerated effect, can select nitrogen gas as the cooling gas, nitrogen gas lets in to casing 1 inside through breather pipe 7 and supplementary breather pipe 8, pivot 601 drives fan 9 and rotates, make nitrogen gas can reach casing 1 inside any place uniformly, because the temperature of nitrogen gas is very low, can rotate outer ring 203, make exhaust hole 201 present the occlusive state, make nitrogen gas circulate in casing 1 inside, need not to discharge from exhaust hole 201, and then accomplish the cooling to the motor, make the motor can work for a long time steadily.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
