生じがちであった。However, according to this conventional method, the coil may be damaged when the embedded hole of the temperature sensor is formed, and the shape of the hole is difficult to be constant, so that the position and orientation of the sensor may be different. There was a tendency for considerable variations to occur.

とによって達成される。According to the present invention, such an object is to insert a dummy simulating the shape of a temperature sensor into a coil having a winding on a core, and to leave the dummy inserted. A method of embedding a temperature sensor in a coil of an electric motor, comprising: shaping the coil in a state; and embedding a temperature sensor in a hole formed by extracting the dummy. To be done.

に基づいて本発明の構成を詳細に説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

により、図１Ａに示したような中間製品３が得られる。FIG. 1 is a process diagram for embedding a temperature sensor according to the present invention. By winding the conductor wire around the teeth 2 of the stator core 1 formed by stacking the electromagnetic steel sheets shown in FIG. 2, the intermediate product 3 as shown in FIG. 1A is obtained.

で、コイル４の外周に樹脂モールドを施すことになる。In this state, since the outer shape of the coil 4 wound around the stator core 1 is not uniform, that is, the coil 4 is thick and thick, the stator core 1 cannot be housed inside the electric motor. Therefore, the coil 4 wound around the stator core 1 is press-shaped by a mold or the like to have a desired shape, and then the outer periphery of the coil 4 is resin-molded.

ダミー５を容易に挿入することが可能である。In the present invention, in a state before press shaping, that is, in the state of the intermediate product shown in FIG.
It is supposed to be pushed into the gap of the coil 4 in advance (FIG. 1B). At this time, since the coil 4 is relatively loosely wound and has a gap, it is possible to easily insert the dummy 5 in the mounting position of the temperature sensor of the coil 4.

で、コイル４が損傷を受けずに済む。If the dummy 5 is removed after shaping the coil 4 with the dummy 5 inserted and applying the resin mold 4a, a hole 6 for embedding the temperature sensor will be formed therein ( Figure 1C). At the time of shaping the coil 4, the dummy 5 is formed of a synthetic resin material, so that the coil 4 is not damaged.
