Winding fixing structure of a rotary transformer-type resolver

摘要

A rotation angle sensor and a method of winding a rotation angle sensor involve a single electrical wire that is wound from a rotor transformer (12) to a magnetic rotor (14). The magnetic rotor (14) is axially spaced on a shaft (11) from the rotor transformer (12). A notch (19) is formed in a wall of a bobbin (13) of the rotor transformer (12) to permit the wire to pass from the rotor transformer (12) to the magnetic rotor (14). The ends (22a, 22b) of the single wire (22) are electrically connected together at a junction, and the junction is fixed to the rotor transformer (12) with resin.
