Description

Technical Field

[0001] The utility model relates to the technical field of stator wire bar size detection, in particular to a stator wire bar size detection device for a molded transposed winding permanent magnet synchronous motor. Background Art

[0002] The stator wire bar is any half of the entire coil, each with a coil side and a corresponding end, which together form a complete coil. The stator wire bar is composed of multiple copper wires and main insulation, and connecting joints are provided at both ends of the wire bar. The so-called wire bar transposition is that the multiple wire strands inside the wire bar are cross-transposed in the straight section of the wire bar. By changing the spatial position of the wire, the magnetic flux of the cross-linked wire strands is made as balanced as possible to generate basically equal induced potentials to eliminate the internal circulation in the wire bar and reduce the wire bar loss. The existing synchronous motor stator wire bar needs to be tested for size during processing to facilitate the next step of processing, and the existing detection cannot be used synchronously for larger stator wire bars. For this reason, we propose a stator wire bar size detection device for a formed transposed winding permanent magnet synchronous motor. Utility Model Content
