Brushless electrical machine includes permanent magnet rotor which is adhered to assembled carrier body, closing gaps left during assembly

摘要

The carrier body (18) is assembled from parts including a cylindrical main body (19) and a tubular ring section (20). This ring is pushed axially onto the carrier body, in a circumferential region (29) lying below the magnet ring (13). It approaches the radial shoulder (21) closely, leaving an axial gap (25). Between the magnet ring and support body there is an annular gap (23). Introduction of adhesive (24) fills and closes the gaps. An Independent claim is included for the corresponding method of manufacture.
