Procedure For Selecting And Evaluating A Special Purpose Motor.
MetadataShow full item record
During recent years, there has been considerable interest in motors. This interest has stemmed from what appears to be an increase in motor problems. As a result of this, along with the need for machinery reliability, manufacturers and users are starting to evaluate the motor's overall performance. In a petroleum or petrochemical facility, the department responsible for motor reliability often consists of mechanical engineers who may have had little or no formal training in motor construction or design. In order to evaluate and troubleshoot motor problems however, their construction features must be understood. In order to understand even the simplest of motor problems, it is important that one have knowledge of the various manufacturing and construction features which make up a motor. Only in this manner can an engineer decide on proper methods of repair, and whether or not they may be in contradiction with the basic design or construction principles. The components and construction features of induction motors are described and a technical tabulation is presented which, when completed by the manufacturer, can be used to evaluate the new motor. In process manufacturing tests normally specified to increase the reliability of motors are also described in detail.
