Rotational transformer for a tape recorder

摘要

A rotational transformer for a rotational transducer in a tape recorder includes a stator piece having a first ring-shaped magnetic core and a stator winding associated therewith. A rotor piece includes a second ring-shaped magnetic core coaxially located with the first ring-shaped magnetic core, a rotor winding and a coil carrier formed of a nonmagnetic material. The carrier is inserted into a ring-shaped recess formed in the second core. The coil carrier is constructed with at least one slot into which wire of the rotor winding is emplaced. The slot is of a width adopted to the size of the wire of the rotor winding.
