Abstract
In an electric motor, a springy disk with internal projections is used to position the iron stator plates of an electric motor by engagement with a soft material of the electric motor bearing support part. The disk is thus fixed with plates of the stator to align the stator plates with the support tube. The disk can be held between an end plate of the stator and the iron plates by windings of the motor. The disk can have tabs or ribs to align the plates properly or can have a pole configuration similar to the plates themselves. Indexing ribs can be located between the disks and the support plate.
