Brushless electric motor yoke producing method, involves withdrawing fingers from cup via passages during displacement of disk to withdrawal position while support is spaced from cup

摘要

The method involves introducing fingers (73) in a cup (15) and in each of multiple introduction passages (31), axially supporting magnets (17) on the fingers, and fixing the magnets on a lateral wall (23) of the cup. The fingers are withdrawn from the cup via the passages during displacement of a disk (71) to a withdrawal position while a support (91) is spaced from the cup. An independent claim is also included for a device to produce a yoke of an electric motor.
