The poles of a DC generator are laminated to
- reduce eddy current losses.
- reduce flux losses.
- reduce hysteresis losses.
Explanation from PART66Online
The poles and magnetic circuit are built from thin insulated laminations to break up the paths available to circulating eddy currents induced by the changing flux, greatly reducing eddy-current heating losses. Hysteresis loss depends on core material, not lamination, and lamination does not reduce useful flux.
