Linear actuator or drive used in e.g. machine tool, based on motor and threaded drive spindle, has rotor implemented as spindle nut of threaded drive unit

摘要

Rotor is implemented as the spindle nut of a threaded drive unit. A recirculating ball unit is employed with a synchronous electrical motor. The rotor (1) is supported by a bearing (6) against a machine component with respect to which, the spindle (5) can be moved.
