Embodiment Construction
[0021] figure 1 For the working principle diagram of the resolver, the primary excitation winding of the resolver (R 1 -R 2 ) and two-phase quadrature secondary pole induction winding (S 1 -S 3 is the first secondary induction winding, S 2 -S 4 For the second secondary induction winding) on the stator side. On the rotor side are the winding coils that are flux coupled to the primary and secondary windings. When the resolver rotor rotates synchronously with the motor, an AC excitation voltage is applied to the primary excitation winding, and an induced electromotive force will be generated in the secondary output winding, which is the product of the excitation and the sine and cosine of the rotor rotation angle. The input and output relationship of the resolver is as follows:
[0022] (1),
[0023] (2),
[0024] (3),
[0025] In the formula: - the maximum amplitude of the excitation...
