Abstract
Disclosed is a resolver, which includes a stator having at least one excitation coil and at least one output coil, and a rotor disposed at a center space in the stator with a predetermined gap from the stator, the rotor rotating based on a rotary shaft to change a gap permeance with respect to the stator, wherein a thickness (tr) of the rotor and a thickness (ts) of the stator satisfies the equation: tr−ts≥0.7 [mm], thereby efficiently offsetting an influence caused by an assembly error, which is commonly generated when assembling a resolver, improving the measurement precision, facilitating a resolver designing work and reducing manufacture costs.
