BRUSHLESS RESOLVER AND ITS CONSTRUCTING METHOD

摘要

A brushless resolver (10) comprises exciting signal transmitting means for transmitting a resolver exciting signal from the stator (3) side to the rotor (4) side in a noncontact way and a resolver part (7) for modulating the resolver exciting signal according to the angle of rotation to be detected. The resolver part (7) also serves as exciting signal transmitting means. The resolver part (7) is constituted of a pair of a rotor (4) composed of a rotor iron core (43) having slots and wrapped with a rotor winding (44) and a stator (3) composed of a stator iron core (33) having slots and wrapped with a stator winding (34). The manufacturing cost can be lowered, and an arbitrary shaft multiple angle such as a shift multiple angle 1 can be set up.
