83 The figure below shows a simplified rotor and stator for a dc motor. The mean path length of the stator is 50 cm, and its cross-sectional area is 12 cm². The mean path length of the rotor is 5 cm, and its cross-sectional area also may be assumed to be 12 cm². Each air gap between the rotor and the stator is 0.05 cm wide, and the crass-sectional area of each air gap (including fringing) is 14 cm². The iron of the core has a relative permeability of 2000, and there are 200 turns of wire on the core. If the current in the wire is adjusted to be 1 A, what will the resulting flux density in the air gaps be?

Answer rating: 100% (QA)

To find the flux density B in the air gaps of the DC motor we can use the formula BorNI where B is t... View the full answer
