Claims30
An actuator, comprising:
- a stator comprising at least one yoke;
- at least one permanent magnet, wherein the at least one permanent magnet is coupled to the stator;
- at least one rotor, the rotor comprises at least one coil winding, wherein the rotor is moving within the magnetic field(s) generated by the permanent magnets, wherein the at least one rotor is above the stator;
- at least one appendage, wherein the at least one appendage is coupled to the rotor;
- a spring element, wherein the spring element is coupled between the rotor and the stator,
- a second stator, wherein the second stator is over the at least one rotor;
- and
- a support connecting the stator and the second stator, wherein the support is configured to limit a range of rotation of the at least one rotor.
