ABSTRACT:
In a VR-type resolver which is used in combination with a motor to detect the rotation position of the motor, the teeth number of a rotor of the resolver is reduced over the teeth number of a rotor of the motor. Also, the shape of the teeth of the resolver rotor is simplified into a curved shape such as a sine wave shape. Further, in another type of VR-type resolver, the number of the magnetic poles of the stator with respect to the number of the teeth of the rotor is set as a number being capable of satisfying not only the condition that it is a multiple of the phase number N and an even number but also the condition that it is a number which can be calculated according to one of the following expressions (1) and (2), that is,
