Construction Features

This series motors employ compact structure popurlar in the world with compactand attracive appearance.Cooling ribs shall be distributed on the inner and outersurface of the frame and end shield.

The stators adopt extermal presure assembly onstructions and ar of Class F insulation,Stators coils are would with insulating fat copper wire,Tthe whole windings are vacumpressure-impreanated to make them possess highest electrical performance. mechanica strenoth,insultion property,moisture resistance and thermo-stabilityThe rotors are of squirel cage structure.After high precision balancing verification,the motors can run smoothly with smal vibration.High-oltage terminal boxes ar seal structure with a large terminal compartment within which postion of cable heads are lef.Theterminal boxes generally locate on the rightside of the motors.The bearing structure shal be selected accordin to diferent output and peed.For frame size H355560 and 4,6, 8p motors, roling bearing shal be provided.For frame sizeH50560 and 2o motors .sleeve bearig shal e provided .For rolin bearing, atachments having the use to replenish the lubricating grease without stoping the motor are set up atboth ends of the bearin.attachments havin the use to repienish orease perodicaly.Sleeve earina. Which is end shield sohere sleeve bearina.s oressure fed ubrication form.oil inaself-lubrcation and combined type ubrication The lubrication form sha! be selected by userPressure feed lubrication form shal be provided f the user has no sneciarequirment,)，The measures to prevent shaft current from generating are taken at the same time.Motors can be equipped with a earing temperature detector to detect bearing temperature and also with a stator temperature detector and an ant-condensation heating deviceon customers request.

The flameproof structures are adopted with the barrel configuration,plain and axial labyrinth etc.
