Core Loss Tester

Material inspection can be very useful where strict quality standards are maintained. It saves a lot of processing cost since lossy material is inspected before it goes to production level. Stack testing is one of the oldest and widely used method for electrical stack testing. Ferrites India Make Core Loss Tester adhere to ASTM, IEC and IS standards and provide accurate results. S30 and S30S Series: Stacks built with punched laminations can have lot of quality issues. Even though the lamination material is tested in sheet format before any process, that alone is not sufficient to guarantee good quality stators. Wear and tear of the punch, bad welding, bad insulating coating in annealing add to the magnetic losses in the stator. It is always advisable to test the stator core in it’s final format before winding to ensure good quality throughout the production batch.
