Abstract
A magnetic resolver includes a stator core made of magnetic material, coils, and a rotor. The stator core has a base plate and protrusions formed integrally with the base plate so as to protrude from a surface of the base plate in the thickness direction. The coils are provided around the respective protrusions. The rotor is disposed so as to face the surface of the base plate with the coils interposed therebetween. The overlapping area between the rotor and each of the protrusions changes with a change in a rotation angle of the rotor relative to the stator core. The stator core has through-holes that pass through the base plate and the respective protrusions in the thickness direction.
