What are the effects of non-conformity of machined parts on the quality level of motors?

Machined Parts Are The Foundation Of The Physical Space Structure Of Motor Products. If There Are Deviations In The Machining Of These Parts, The Quality Of The Motor Will Be Reduced. In Serious Cases, The Motor Will Be Able To Operate Normally.

(1) Uneven Air Gap Bore Cleaning Quality Problems Caused By The Non-Concentricity Of The Machine Base. The Coaxiality Requirement Between The Two Ends Of The Machine Base The Stator Core Is A Key Issue That Must Be Guaranteed In The Processing Technology. In Addition To The Non-Concentricity Problem, Similar Problems Will Also Occur When The End Face Of The Machine Base Is Straight With The Center Line, But The Fault Location Is Different Due To Different Reasons.

(2) Uneven Air Gap Bore Sweeping Quality Problems Caused By Rotor Misalignment. The Rotor Is A Component Composed Of A Shaft An Iron Core. In Addition To The Cooperative Relationship Between The Two, Both Use The Center Holes At Both Ends Of The Shaft As The Processing Reference During The Machining Process. Because The Shaft Machining Requires Multiple Processing Steps, The Rotor Surface Turning Is Another Process, During Repeated Processing, If The Processing Reference Is Damaged, The Center Hole Itself Is Well Processed, It Will Cause The Cylindrical Surface To Be Eccentric During The Processing. Therefore, During The Machining Process, The Center Hole Itself The Processing Subsequent Protection Are The Key Points Of The Mechanical Processing Of The Motor Rotor Part.

(3) The Motor Performance Parameters Do Meet The Requirements Due To The Non-Compliance Of The Rotor Outer Diameter. For Asynchronous Motor Products, The Air Gap Between The Stator The Rotor Directly Affects The Current Loss Of The Motor. When The Outer Diameter Of The Rotor Core Is Too Small, The Motor Air Gap Will Be Larger Than The Designed Value, Resulting In A Decrease In The Stator Harmonic Leakage Reactance The Rotor Harmonic Leakage Reactance, The Total Leakage Reactance Of The Motor Will Decrease Accordingly, Thus Increasing The Starting Current. At The Same Time, It Also Leads To An Increase In The Air Gap Magnetomotive Force No-Load Current, A Decrease In The Power Factor, An Increase In The Stator Current Stator Copper Loss, A Decrease In Power, An Increase In Temperature Rise.
