Abstract
Official abstract text for this publication.
Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a rotor for use in a motor, said method comprising the steps of: (a) forming a core to define a plurality of arcuately spaced apart magnet-receiving slots; (b) inserting a plurality of magnets into corresponding ones of the slots; and (c) deforming the core along each of the slots to define a securement portion that extends along and projects radially into the corresponding slot to engage the respective magnet and thereby secure the respective magnet in the slot. 2. The method as claimed in claim 1 , step (a) including the steps of punching a plurality of laminations and stacking the laminations. 3. The method as claimed in claim 2 , step (c) including the step of stamping a selected number of the laminations so that the securement portion has a total axial extent that is less than the core axial height.
