Vibration Analysis of Vertically Mounted Motor of the Diamond Polishing Machine

Abstract

The most precious ornamental parts consist of diamonds of different verities. These diamonds are the special stones which are polished to their final forms and shines. To polish these stones to premium quality, diamond polishing machines are being used in diamond polishing industries. In general these machines having horizontal grinding wheel that attached to a vertically mounted shaft in induction motor assembly. The polishing of these diamonds is really crucial. Any small amount of vibration leads to create scratches on the surface of the diamond. There are many causes that produce vibration in motor that include critical speed, mechanical unbalance, different mechanical effects, electrical effects and also affected by external sources. To get highest quality of diamond from diamond polishing machine, these causes must be nullify or reduced to a particular limit. The main aim is to find the causes of vibration in vertically mounted diamond polishing motor. By using different techniques to this project it is possible to reach towards the root of the cause and minimize the adverse effects appearing in the motor. CAD software and FEA packages are used to model and simulate results of vertically mounted diamond polishing motor for vibration studies.
