Abstract
The utility model provides a box-type positive-pressure synchronous motor. The motor comprises a stator, end caps, wind shields, bearings, a cooler, an AC exciter, an exciter armature, a rotary rectification disc, a rotor, a purge pipe, a positive pressure control device and a support. The cooler is located above the support. The end caps are connected to the left and the right ends of the support. The stator is under the cooler. The wind shields are fixed on two sides of the stator, and the bearings are fixedly installed at the centers of the end caps on two sides. The end caps, the cooler and the support form a box-type structure of the motor together. The exciter armature is on the left side of the bearing on the right end of the motor. The AC exciter is on the upper end of the exciter armature. The rotary rectification disc is on the left side of the exciter armature. The motor is good in sealing performance and easy to install, transport and maintain.
Description
Technical field
The utility model relates to a kind of large-sized low-speed positive pressure type brushless exciting synchronous motor, particularly a kind of box positive pressure type synchronous motor.
Background technology
Large-sized low-speed positive pressure type brushless exciting synchronous motor tradition adopts seat formula structure, installation pattern is IM7315, is made up of parts such as cooler, outer cover, base plate, end cover, exciter, axle perforations, exists parts junction more, leakage rate is larger, installs, transports the shortcomings such as inconvenient.Synchronous motor when maintenance, need to be by stator same time, close to winch to and exceed base plate plane, then rotor could be extracted out, maintenance very trouble and cost higher.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing property better, is convenient to the box positive pressure type synchronous motor of installing, transporting and safeguard.
To achieve these goals, box positive pressure type synchronous motor of the present utility model comprises stator, end cap, deep bead, bearing, cooler, AC exciter, armature of exciter, rotating rectifier dish, rotor, purge pipeline, positive pressure control device and support, cooler is positioned at support top, end cap is connected in two ends, support left and right, stator is positioned at cooler below, deep bead is fixed on stator both sides, bearing is fixedly installed in end cap center, both sides, described end cap, cooler and support have formed the case structure of box positive pressure type synchronous motor jointly, armature of exciter is positioned at the left side of motor right-hand member bearing, AC exciter is positioned at the upper end of armature of exciter, rotating rectifier dish is positioned at armature of exciter left side.
Described purging pipeline is motor base positive pressure ventilation pipe layout.
Described end cap is integral end cap.
The outside weld seam of described box positive pressure type synchronous motor is all taked full weld.
The construction bolt hole that leaks outside in described stator is all blind hole.
Than prior art, the utility model has reduced the structure such as outer cover, end cover, and end cap is integral end cap, thereby has reduced the bound fraction between each parts, is more prone to sealing,
Reduce leakage rate, be conducive to the pressurize of positive Medium-voltage Motor, also improved degree of protection simultaneously; AC exciter and rotating rectifier dish are positioned at bearing inner side, have shortened axial length, and whole motor is compacter, easy transportation and installation; The utility model entirety is case structure, and rotor can directly be extracted out, convenient maintenance, and reduced hoisting weight, save the cost of overhaul.
