Abstract
The utility model discloses a kind of built-in impeller auxiliary heat dissipation towing machine, comprise the main shaft be arranged between front end cover and rear side housing, stator, rotor, described rotor comprises driving surface and spoke, and described spoke becomes impeller shape, and described driving surface and described spoke are permanent-magnet material.The utility model rotor drives elevator knee-action, the rotor of towing machine must positive and negatively rotate, the spoke of rotor equals the positive and negative rotation of blower fan, like this, at the air extractor vent of the front and rear cover of towing machine, one side air-breathing will be formed while the effect of exhaust alternating movement, ceaselessly the air outside towing machine is taken in towing machine, reach air-cooled effect, traction function is normally worked for a long time, and the aging of towing machine can also be delayed, extend the life-span of towing machine.
Description
Technical field
The utility model relates to a kind of lift appliance, is specifically related to a kind of built-in impeller auxiliary heat dissipation towing machine.
Background technology
Towing machine is the drive element of elevator, is also one of core component.Existing permanent-magnet synchronous variable frequency dragging engine efficiency is high, energy-conservation, sound is low, environmental protection, is unanimously approved by people.But towing machine operationally, can generate heat, frequently use, cal val is larger.The rotor material permanent magnet of towing machine and the change of stator material enamel wire Dou Hui Yin Wendu and change performance, briefly, efficiency and the temperature of towing machine are inversely proportional to, and temperature is higher, and efficiency is lower.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of built-in impeller auxiliary heat dissipation towing machine, spoke is processed into impeller shape, when towing machine rotates, produce air-flow, by the pore on end cap, the thermal current in towing machine can be mutual with the cold airflow outside towing machine, reaches the effect reducing towing machine temperature.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of built-in impeller auxiliary heat dissipation towing machine, comprise the main shaft be arranged between front end cover and rear side housing, stator, rotor, described rotor comprises driving surface and spoke, and described spoke becomes impeller shape.
Further, described driving surface and described spoke are permanent-magnet material.
The beneficial effects of the utility model are:
The utility model rotor drives elevator knee-action, the rotor of towing machine must positive and negatively rotate, the spoke of rotor equals the positive and negative rotation of blower fan, like this, at the air extractor vent of the front and rear cover of towing machine, one side air-breathing will be formed while the effect of exhaust alternating movement, ceaselessly the air outside towing machine is taken in towing machine, reach air-cooled effect, traction function is normally worked for a long time, and the aging of towing machine can also be delayed, extend the life-span of towing machine.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
