Electric motor or converter with air gap winding and process for its manufacture

摘要

A slotless stator for an electromechanical transducer, said stator including a stator shell (30) and a pre-formed, at least partially rigid, self-supporting winding structure having active segments and end-turns (40), is produced by a method that comprises depositing insulated wire on a support, adhesively affixing at least active wire segments portions to the support surface or previously deposited wires, with the active wire segments arranged in predetermined, substantially fixed positions with respect to each other, encapsulating and securely attaching the winding structure to the stator shell, and combining the completed stator with a structure including at least one permanent magnet mounted for movement relative to the stator. In a preferred embodiment, the self-supporting winding structure is removed from the support surface prior to insertion in the stator shell. IMAGE
