Plastic encapsulated electrodynamic apparatus

摘要

Method and apparatus for forming an electrodynamic device such as a motor or generator. The device is formed with an encapsulation structure which is developed by insert molding. A rigid pressed powder stator core and stator backiron subassembly with associated stator core windings is formed. This subassembly is the insert for an insert molding procedure developing an encapsulation structure which mechanically supports the stator structure; provides mechanical support and improved heat dissipation and incorporates integrally formed bearing mounts. With the procedure, substantially lower device costs are realized.
