を樹脂でモールドする。BACKGROUND OF THE INVENTION A conventional resin molded motor will be described below. As shown in FIGS. 4 and 5, a protector storage section 12 is provided in the connector 11, and the protector 4 is placed therein.
The protector storage section 12 is designed to prevent the protector 4 from deforming.
After covering with a lid 13, the entire stator core including the coils is molded with resin.

問題点を有していた。Problems to be Solved by the Invention However, in the conventional configuration described above, since the protector is covered with the connector housing and the lid, an air layer exists around the protector without being filled with resin, which deteriorates the temperature sensitivity of the protector. When the temperature suddenly rises, such as when the motor locks up, the temperature of the bearing exceeds the set temperature of the protector, causing problems such as abnormal bearing noise. However, when the set temperature of the protector is lowered, there is a problem in that the protector operates even under normal usage conditions.
