COMMUTATING ROTARY TRANSFORMER

摘要

Commutating rotary transformer having a primary section which rotates with the head assembly and a stationary secondary section which is mounted adjacent to the primary section. The primary section has a plurality of arcuately disposed windings wound on radially extending magnetic core segments, the number of windings and core segments corresponding to the number of heads. The secondary section has an arcuately disposed winding wound on a radially extending magnetic core segment which is disposed to be aligned successively with different ones of the primary core segments as the primary section rotates, whereby the signals from different ones of the rotating transducer heads are successively coupled to the stationary secondary winding.
