Title:
RESIN MOLDED TYPE MOTOR
Document Type and Number:
Japanese Patent JPS5783136
Kind Code:
A
Abstract:
PURPOSE:To enable a dielectric resistance test between a stator coil and a stator core, and to improve a cooling effect by forming a through-hole in the axial direction to a section having small magnetic flux density of the core and exposing the surface of the core into the through-hole even after molding with resin. CONSTITUTION:The through-hole 5 penetrating in the axial direction is shaped previously to a corner section, etc. having small magnetic flux density of the stator core 4. When the stator coil 7 and the stator core 4 are integrally molded with resin 8, a hole 13 is formed to the through-hole 5 section so that the core 4 is exposed, and the coil and the core are molded. Accordingly, the dielectric resistance test between the stator core 4 and the stator coil 7 can be executed even after molding, and cooling is also improved.
