Silicon steel sheet, mainly used for the iron core in motor, generator and transformer, is the indispensable soft magnetic material for electricity, electronics and military industry. The fabrication technique and product quality of silicon steel sheet is one of important demonstrations to measure special steel production and technology development of a country. Iron loss is a key indicator for the quality of silicon steel sheet. An ARM7-based automatic measurement system for the iron loss of single silicon steel sheet is presented in this paper. It is discussed from both theory and practical application how to measure the iron loss of single silicon steel sheet with different thickness and density under the condition of different magnetic flux density. Finally, the main components of the system: excitation circuit, power supply and software design are introduced.
