Abstract:
1. A variable reluctance resolver comprising: a rotor; a circular stator core provided with a plurality of salient poles; a circular insulator insulating the stator core; a stator coil wound to the salient poles of the stator core via the insulator and having end portions; a base formed together with the circular insulator at a radially outside location of the circular insulator and extending away from the circular insulator; terminal pins that are arranged on the base and are connected with the end portions of the stator coil; and a cover that is mounted to the base and covers the terminal pins so that the terminal pins are not exposed to the outside, wherein the base and the cover form a hollow portion therebetween, and the hollow portion is filled with a non-conductive material as a filler, the hollow portion faces the stator coil and includes an opening disposed between the terminal pins and the stator coil, leads of the stator coil are extended into an inside of the hollow portion through the opening and connected to the terminal pins, the terminal pins and the leads of the stator coil, which are connected to the terminal pins, are sealed in the filler of the non-conductive material in the hollow portion, and an end surface of the filler of the non-conductive material in the hollow portion is positioned at the opening.
