Electrical output generating devices and driven electrical devices having tape wound core laminate rotor or stator elements. The tape wound core portions enhance magnetic flux and may be shaped and cut to receive magnet and/or flux conducting portions in corresponding stator or rotor portions of devices. The devices can include cooling features integral with the stator and/or rotor portions and superconducting elements. The tape wound core portions can be contained in housings and/or be impregnated with adhesive or other bonding so as to maintain shape and to protect the tape wound core portions during operation of the device. In some variations, the housings can include features for simplifying the adhesive/bonding process.
