Abstract
A primary for a linear drive motor has first and second stacks, each with inner and outer teeth and a bearing mount. A magnet is disposed between the first and second stacks, and a coil wrapped is between the first and second stacks. A bearing is operatively mounted to at least one of the bearing mounts of the first and second stacks. The outer teeth of the first and second stacks may have a projection comprising the bearing mount. The bearing mount may be embedded within the stacks. The stacks may be assembled in a housing and the housing may have a first bearing outboard of the first stack, a second bearing outboard of the second stack, and a third bearing in staggered relationship with the first and second bearings across the housing in an arrangement bilaterally symmetric about an axis transverse to the direction of travel.
