Flux density calculation in transformer
WebCalculate the flux density in tesla for a 200µWb flux through an area of 5 x 10-4 sq. m. arrow_forward An iron core has a cross-sectional area of 10-3 square meter and mean circumference of 1 meter. The relative permeability of the material is 500 and the number of turns is 200. Determine the current required to set up a flux of 0.001 weber. WebIdeal Transformer. Because we are dealing with balanced 3-phase motors we can achieve considerable simplification by developing single-phase models, it being understood that any calculations using the equivalent circuit (e.g. torque or power) will yield ‘per phase’ values which will be multiplied by three to give the total torque or power.
