Description
Technical field:
The utility model relates to a kind of threephase asynchronous, is applicable to that the main transmission of elevator driving, electrically operated valve, metal cutting machinery, woodworking machinery, textile machine, rubber chemicals machinery, printing machinery, metal forming machinery, deceleration machinery and various types of lathes of hoisting equipment and accessory drives etc. need fast, in the various machineries of accurate stopping.
Background technology:
The generation that a lot of threephase asynchronouses of use cause the accident easily under some mine at present, price is also somewhat expensive, useful life is also shorter, structure is more complicated also, and manufacturing cost is burnt in the condition lower coil of high load capacity easily also than higher, and the torque of motor is not high, performance is poor, and operating efficiency is not high, is unfavorable for the popularization in market.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, a kind of threephase asynchronous that cost is low is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of threephase asynchronous; comprise housing; the enclosure interior center is provided with horizontally set and through the main shaft of housing; housing left end and right-hand member all are connected with end cap; described housing top links to each other with terminal box; described housing center is provided with main shaft; main shaft mainly is exactly for outputting power; described main shaft links to each other with rotor; and described rotor is positioned at described main shaft top; the rotor top is provided with stator; described stator is fixed on the described inner walls, and all by being bolted on the housing, the bolt at two ends, the described left and right sides all is positioned at the upper end-face edge position of described left and right sides end cap to described left and right sides end cap; right-hand member end cap right side is equipped with fan by main shaft; fan has thermolysis, guarantees the normal operation of motor, and described fan is surrounded by fan housing; fan housing links to each other with described housing, and fan housing has the effect when dust and protection.
The utlity model has following advantage: the torque of motor output is big, and power is strong, low cost of manufacture, and long service life, structure are very simple, and high efficiency, price are also very cheap, can turn round under the condition of high load capacity, are beneficial to the popularization in market.
Description of drawings:
