The rotor (5) includes magnet modules (52a, 52b, 52c) arranged in an annular shape with a rotary shaft as a center. Each magnet module includes a base (6) formed of a magnetic material, and two rotor magnets (7, 8) having poles different from each other and provided with a gap therebetween in the rotation direction of the rotary shaft on an outer circumferential surface of the base. The abutting rotor magnets of two magnet modules adjacent in the rotation direction have the same pole and are in close contact with each other.

摘要： In a related-art resolver, a front and a back of a stator core (3) cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator (2) including: a stator core (3) formed of electromagnetic steel sheets, which have teeth (3a), and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor (1) arranged to be opposed to the resolver stator (2), in which the stator core (3) has marks (3b) which enable distinction of a rolling direction of the stator core (3) and distinction of a front and a back of the stator core.

摘要： The rectifying device (100) converts high-frequency power input from an input terminal (5) into direct current power and outputs the direct current power from an output terminal (6). The rectifying device (100) includes a rectifier (1) that converts the high-frequency power into the direct current power, and an impedance changer (4) having one end connected to a connection point of the rectifier (1) and the output terminal (6) and the other end to which reference voltage is applied such that impedance varies while having a negative correlation with respect to an absolute value of voltage of the direct current power. When the absolute value of the voltage of the direct current power is greater than a predetermined value that is lower than reverse withstand voltage of the rectifying element included in the rectifier (1), the impedance of the impedance changer (4) as viewed from the rectifier (1) is a value regarded as corresponding to a short circuit.
