Electrical Steel Material Testing
Epstein Testing: Electrical steel is measured for core loss and permeability using a Brockhaus MPG 200 automated test system Epstein test frames, multiple Tesla and frequency inputs based on ASTM A717 test method.
Single Sheet Testing (SST): Each coil of electrical steel is measured for NLL (no load losses) and permeability using a modern SST. This equipment is capable of measuring domain refined electrical steel.
Franklin Testing: A unique method of testing single strips of flat rolled electrical steel for surface insulation resistance under pre-determined voltage, temperature and pressure conditions.
Dimensional Testing: Each coil of electrical steel is measured for variations in material thickness and width based on ASTM A971 test method.
Assembled Core Electrical Testing
Assembled Core Electrical Testing: All assembled SLFM and DG cores are 100% tested on automated Yokogawa precision power analyzers to customer specifications guaranteeing that NLL (no load losses) are met.
Special Electrical Product Testing: Upon request, assembled SLFM and DG core can also be tested for insulation resistance and sound over a wide range of flux densities and frequencies. Detailed test reports and curve graphs may be provided.
All dimensional specifications are confirmed using digital measurement equipment.
First piece and PPAP inspection: Layout inspection and/or functional verification to customer engineered performance specification may be made available upon request.
