why are laminated rotor cores used in dc machines (with dc current in the rotor) when there is no possibility of eddy current (or is there?).
Click For Summary
SUMMARY
Laminated rotor cores are essential in DC machines to mitigate eddy currents, particularly when the rotor features a commutator. Despite the presence of DC current in the rotor windings, the alternating nature of the currents necessitates the use of laminated cores to enhance efficiency and reduce losses. In configurations with slip rings, the currents approach DC, yet lamination remains beneficial for optimal performance.
