Spindle rotor electric motor for positioning and linear drive - with motor housing displaced axially along spindle upon its rotation

摘要

The spindle rotor electric motor has a motor housing (3) enclosing a stator winding (2) supported by the spindle (9) by axially spaced bearings (8) at both ends. The motor housing is displaced axially along the spindle (9) upon rotation of the latter. The armature (15) of the electric motor pref. incorporates spindle washers (13) at each end. USE - For precision positioning and linear drive in machine tool, handling appts. or ind. robot etc.
