Abstract
The utility model discloses a ventilation cooling system of a three-phase asynchronous motor, which is mounted on the three-phase asynchronous motor. The motor comprises an engine base, a front end cover and a rear end cover. A stator is mounted inside the engine base, a motor shaft is arranged in the center inside the engine base and a rotor is fixed on the motor shaft, wherein the slot combination ratio of the stator to the rotor is 48:36; a plurality of arc radiating holes are uniformly arranged in the rear end cover by surrounding the motor shaft; the front of the front end cover is uniformly provided with a plurality of air holes and the side of the front end cover is provided with a ventilation duct; and the inner surface of the engine base is provided with a plurality of ventilating slots. The cooling system has the beneficial effects that the radiating effect is good, a material consumption problem caused by a radiating fin and a noise problem caused by a fan can be avoided, the noise is reduced to great extent in the running process of the motor, and compared with similar motors, the structure is more compact and the volume is decreased considerably.
Description
Technical field
The utility model relates to a kind of threephase asynchronous, particularly a kind of aeration radiation system that is applied to the frequency control threephase asynchronous of lift facility.
Background technology
The heat radiation of high-speed electric expreess locomotive generally is to add fin on the housing of motor at present, utilizes fin to carry out the heat energy that motor rotation produces is distributed; Simultaneously, also there is considerable manufacturing enterprise to adopt the form that installs fan additional to carry out to motor radiating.
For the radiating mode that adopts fin, increase several cooling fins at the housing of motor, can increase the weight of whole motor, consumptive material is also more relatively, in face of present national resources reality more and more in short supply, also is that national development is not advocated obviously.
And install the radiating mode of fan additional for employing, because fan can produce very big noise in the process of running, be unsuitable for using particular environment such as places such as residential block, elevator.In addition, set up the physical dimension that motor also can increase whole motor.
The utility model content
The purpose of this utility model provides the aeration radiation system of threephase asynchronous, at motor itself cooling system is set, and can solve problems such as the cost that adopts fin, fan to carry out radiating mode to bring, noise, consumptive material.
The purpose of this utility model is to be achieved through the following technical solutions:
The aeration radiation system of threephase asynchronous is installed on the threephase asynchronous, and described motor comprises support, front end housing, rear end cap, in base inner stator is installed, and base inner central authorities are provided with motor shaft, fixed rotor on motor shaft; Wherein the groove mixing ratio of stator and rotor is 48: 36, evenly is provided with the multilayer louvre around motor shaft on the described rear end cap, and described louvre is an arc; The front of described front end housing evenly is provided with some ventilation holes, and is provided with air duct in the side of front end housing; The inner surface of described support is provided with some ventilation slots.
The beneficial effects of the utility model are, have better heat radiating effect, the noise problem that can avoid consumptive material problem that fin brings and fan to bring, motor noise in the process of running reduces significantly, and compact more than similar electric machine structure, volume greatly reduces.
