Determine the power output from a Dc motor that draws an armature current of 20A from a 230V supply. Rotor diameter and length = 0.2m. Flux density = 0.5T. Armature winding has 200 conductors with 2 parallel paths. Resistance of armature is 0.5 ohms? I am having trouble figuring out how to use these values of conductors, parallel paths etc to get to a solution.
