)の成形時間が長くなって、製造効率が悪くなった。[Problem to be solved by the invention] However, in the conventional electric motor housing structure,
As described above, since the control circuit board 1f (44) and the electronic components (45) are molded in a bare state, their entire surfaces come into direct contact with the molten synthetic resin at high temperature and high pressure. For this reason, when electronic components (45) with low heat and pressure resistance such as electrolytic capacitors, glass tube fuses, glass-sealed diodes, or Zener diodes are used, their characteristics may change due to the heat and pressure during molding. Not only was there a risk of deterioration, but there was also a possibility that the lead wire of the electronic component (45) would be disconnected from the control circuit board (44). Therefore, in the conventional housing structure, in order to avoid such characteristic deterioration or wire breakage, it is necessary to set the molding temperature and resin injection pressure low.
), the molding time became longer and manufacturing efficiency deteriorated.

回路基板(44)から断線したりする可能性があった。Moreover, the molding material of the housing (1) and the electronic component (4)
5) and the control circuit board (44) have different coefficients of thermal expansion and contraction. Therefore, during molding and operation, stress caused by the difference in thermal expansion or contraction causes the electronic parts (45) and There was a possibility that the control circuit board (44) would be deformed and destroyed, or that the lead wire of the electronic component (45) would be disconnected from the control circuit board (44).

ある。[Means for Solving the Problems] In order to solve the above problems, the housing structure of the electric motor of the present invention mounts electronic components on a control circuit board, and coats the electronic components and the control circuit board with an elastic protective film. The control circuit board and electronic components are molded together with the stator core and windings using a synthetic resin material.

Furthermore, since the molding temperature and resin injection pressure can be set higher than in the past, the housing can be molded efficiently in a short time. Furthermore, stress caused by differential thermal expansion or contraction during molding or operation is absorbed and alleviated by the elasticity of the protective film, thereby preventing destruction and disconnection of electronic components and control circuit boards.
