초록

In an embodiment, an actuator includes a plurality of stator windings adapted to produce a first stator magnetic field that translates along a stator axis, and to produce a second stator magnetic field that rotates around the stator axis. In addition, the actuator includes a rotor, coupled to a shaft, and positioned within a central stator channel. The rotor is adapted to produce a first rotor magnetic field that translates along a shaft axis and to produce a second rotor magnetic field that rotates around the shaft axis. An actuator system includes an a...

청구항

1. A method for controlling an actuator that includes a stator, a rotor, and a shaft, the method comprising: providing first actuator inputs to produce a first translating magnetic field in the stator and a second translating magnetic field in the rotor;providing second actuator inputs to produce a first rotating magnetic field in the stator and a second rotating magnetic field in the rotor;receiving feedback signals that indicate actual translation and actual rotation;when an evaluation of the feedback signals indicates that a desired translation has no...
