Influence of material quality on the magnetic and mechanical properties of steel sheet for salient pole electrical machines

Abstract Different steel qualities have been investigated for their suitability as pole sheets in synchronous machines with salient poles, which are applied in hydro-electric power stations. The European standard EN 10265: 1995 on magnetic materials—specification for steel sheet and strip with specified mechanical properties and magnetic permeability—served as a guideline. Attention is devoted to the measurement of DC magnetic properties of the material. A survey on the mechanical and magnetic properties of the examined material qualities (hot rolled and cold rolled materials) is given.
