The flame-proof type electromagnetic braking three-phase asynchronous motor comprises a main motor casing, a front end cap and a back end cap, which are both connected with the main motor casing, and a back cover, an electromagnetic brake is installed in the back cover, and the main motor casing, the front end cap and the back end cap are connected with flame-proof adjoining planes, the back end cap is connected with the brake disc of the electromagnetic brake through an adjoining plane, and the main shaft of the motor is connected with the back cover through an adjoining plane.
Description
Technical field
The utility model relates to a kind of threephase asynchronous, a kind of specifically flame-proof type electromagnetic braking threephase asynchronous.
Background technology
In recent years, market is growing to the demand of the flame-proof type threephase asynchronous that has braking function, and the special requirement motor can be accomplished quick parking, accurately location and frequent starting in actual motion.
The utility model content
The purpose of this utility model provides a kind of flame-proof type electromagnetic braking threephase asynchronous, substitutes existing motor commonly used, realizes stopping fast, the accurate function of location and frequent starting.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of flame-proof type electromagnetic braking threephase asynchronous, comprise main case, the front end housing that is connected with main case and rear end cap, the bonnet that is connected with rear end cap, connect terminal box on the main case, at the inner electromagnetic brake of installing of bonnet, main case is connected by flameproof joint with front end housing, rear end cap, and rear end cap is connected by explosion-proof composition surface with the brake disc of electromagnetic brake, and electric machine main shaft is connected by flameproof joint with bonnet.
This motor is that a flameproof motor adds a SDZ type electromagnetism electricity loss brake and combines, and explosion-proof performance meets the regulation of GB3836.1-2000 " explosive gas atmosphere electrical installation part 1: general requirement ", GB3836.2-2000 " explosive gas atmosphere electrical installation part 1: flame-proof type " d " ".
The electromagnetism electricity loss brake mainly contains main parts size such as excitation part, brake disc spline housing and forms.The excitation part is installed on the rear end cap by mounting screw, adjusts corresponding air gap to setting, oppositely screws out hollow bolt, holds out against the excitation part.Spline housing links to each other with power transmission shaft by key, and brake disc and spline housing pass through spline engagement.When coil blackout, under the effect of spring force, brake disc and armature, rear end cap end face produce frictional force, give power transmission shaft by the spline housing transmission, make the axle braking.Behind coil electricity, under the electromagnetic force effect, armature is attracted to yoke, and brake disc is unclamped, and the power transmission shaft braking is removed.The function of rectifier is to provide direct voltage for brake coil.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
