Worried about whether rewinding a motor will degrade its efficiency? Well rewind away. Findings from a study by the Electrical Apparatus Service Association conclude that motors can be rewound multiple times with no loss of efficiency, so long as it's done carefully and operators follow standard procedures. The study examined 50 to 300 hp electric motors with ratings of 1,800 and 3,600 rpm.
Determining the quantities and location of sensors in an Internet of Things application requires a thorough problem statement and a clear vision of success, an expert will tell engineers at the upcoming Design & Manufacturing Show in Minneapolis.
