Effects of Manufacturing Processes on Core Losses of Electrical Machines

Manufacturing processes such as cutting, welding and shrink fitting are known to degrade the magnetic properties of electrical sheet during manufacturing machines. These effects often neglected at design stage lead large errors in simulated measured core losses machine. This article studies comparative impact different on stator a typical industrial motor. Both simulations measurements indicate significant losses. A dummy blocked rotor test setup is used measure As result processes, increased by 23% studied machine rated condition. The effect was higher lower flux levels. Finally, it shown that inclusion significantly improved simulation accuracy quantification segregation also presented for
