Core losses design parameters

The steel of laminations plays a very significant role in determining the heating and the power factor of a motor. See Section 1.6.2A(iv). A better design with a judicious choice of flux density, steel of laminations and its thickness are essential design parameters for a motor to limit the core losses to a low level. 

Table 4. Nucleosynthesis results for 15 massive star models computed up to silicon ignition (Langer Henkel 1995). The symbols have the following meanings Mi is the initial stellar mass, and Z the metallicity. asc is the semiconvective mixing parameter, with asc = 0 corresponding to the Ledoux criterion, asc = oo to the Schwarzschild criterion for convection. Mf is the final stellar mass, Mco the final CO-core mass and Mrem is the assumed remnant mass. Me and Mo are the total mass of carbon and oxygen ejected by stellar wind mass loss and by the supernova explosion (initially present amounts are not subtracted). The values /13. .. /is designate production factors for 13C, 14N, 170, and lsO, and AY/ AZ is the ratio of the net yields of helium to metals.
