dc machines cores
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?).

If the rotor has a commutator, the currents in the rotor windings are not dc, and the core must be laminated. If the rotor has slip rings, the currents are almost dc.
